Optimizing battery run time and battery life Faulty setting

Question: Optimizing battery run time and battery life Faulty setting

On windows 7 this mode on Energy management software limits the charge percentage to 60% on Z580 But the charging doesnot stop it keeps charging and discharing to keep the level stable at 60%. Does that not void the whole point of running this mode?

Preferred Solution: Optimizing battery run time and battery life Faulty setting

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Optimizing battery run time and battery life Faulty setting

Welcome to the forum toxicdevil.

The Energy Management for Win 7 is behaving normally. There is a 5% range, for when the system will initiate the charging sequence. It should begin charging when the battery gets down to 55%, and stop at 60%. If your gauge does not stop charging at 60% (Plugged In, Not Charging) you could have a problem.

Also, I noticed in your other post, you had upgraded to Win 8.1.

EDITED: Here are the Energy Management drivers for the Z580 under Win 8.1:

Everyone knows that Li-Io batteriey life span is reduced if they are kept at 100% charge. Lenovo states this for various models and used to have for this particular reason a setting in the power manager for the W series (and several others) where one could adjust the maximum charge level. After 98 charge cycles, the 100Wh battery of a W540 is down to 37% capacity, leaving it running on battery only for a little over 1:30h. In a previous model or version of the power manager, I could specify whether I want to extend the life of my battery (I work mostly stationary) or whether I need it to charge to 100% as I have a business trip coming up. I'm up to date per Lenovo Sytem Update - but there es no setting to select the maximum charge level in the settings app. Where did that go? Thanks!  Some quotes from Lenovo:"Lenovo has included a battery 'Conservation Mode', which prolongs your battery longevity (how long the battery will tend to last before finally needing to be replaced ) by limiting charging to battery to 55% ~ 60% of the battery capacity rather than fully charging it to 100%.  The trade off is that the system will not run as many hours as would otherwise be possible with a 100% charge." "Keeping your battery charged to 100% all the time may reduce the lifespan of the battery.

Hey, I really need help. I'm having problems with my laptop. It's a dell inspiron 7559 and was bought around January. Recently I have seen that the battery has no longer been as hot as it used to be when I first started using it. Along with the sleeve on the tip of the screen power adapter (below the part where the adapter lights up) has started to come off, exposing the wires. The battery has continually dropped down its percentage rate ever since I bought it, and it won't go back up. It is currently at 0% battery life and it says when you highlight over the battery icon ( plugged in, not charging). It also happens to show the BIO setup when I start the computer and shows that the batteries wattage and type cannot be determined. In the BIOS setup, the ac adapter type is unknown. The battery has not been through any harsh conditions along with the laptop. I have tried removing the battery, starting up the computer with the ac adapter (which is 130 watts), then adding the battery back, and ac adapter, then turning it on, but it had no effects. If I remove my ac adapter while my computer is on ,it instantly turns off. If someone can support me with this issue, it would be gladly appreciated. Thanks.

It sounds likely the charge circuit on the mainboard is damaged.  Contact Dell to have the mainboard replaced under warranty.

I really do not have a preference to which OS that I use, either XP Pro or Vista Business (although have never used Vista before) but I am wondering if using one verse the other would help increase and stretch the battery life.  If all things being equal as far as functions, radios turned on, screen brightness and such, will one give me longer run times than the other? I have read a few entries and there seems to be more updates, revisions and features are being developed and put into Lenovo's management systems for Vista, so I am wondering if perhaps that would have any difference as well. One more thing, has there been any updates/upgrades since Feb or March that would make a difference in the run time of the battery life with either Vista, XP or any of the Lenovo management systems?  I ask because I read the review at notebookreview and I was shocked that they only got about 3 1/2 to 4 hours of use from the X300 and the T400 is getting over 6 1/2 hours and both machines are using 6 cell batteries. 

Answer:Does OS effect battery run time/life?

As a rule of the thumb, XP gives better battery life than Vista, at least on the machines that I've had both on which would include T42p, T43p, X61s (ultralight LCD) and T61p. Hope this helps.

Hi, Lenovo claims the X1 (4th gen) or X1 Yoga can last 11 hours on battery. Great numbers but I guess nobody experienced it.The best I can get is a top 5 hours making sure that the system is on power save mode and about 6 hours when the Battery saver is enabled on Windows 10. I had to install a program to switch to save mode every time the laptop is running on battery. If not I forget to switch to Power Save mode and the battery only last 2 hours. I also pay attention to background program that may eat CPU.Honestly, 6 hours of battery life is pretty good but not even close the 11 hours claimed by Lenovo. The new X1 will have 16 hours of battery life, it means 8 hours in reality.Here are my questions.How many hours do you get on your X1 4gen or X1 Yoga?What did you do to improve it?Any secret recipe?

I have a Lenovo Thinkpad X220 which is about 19 months old.  When at work, the computer is in a Lenovo docking station.  At the end of the day, it is removed and any further evening use is typically on the battery. Yesterday, the battery symbol in the tray at the bottom of the screen displayed a red X on it and indicated that there was an "error".  I presume from this that that battery is dead and needs to be replaced.  I am surprised by the comparatively short life of this battery. I was thinking that perhaps the use of the powered docking station played some role in shortening the battery's life.  For example, it may have repeatedly overcharged the battery. Is there a Power Manager setting that will reduce the likelihood that the battery is being overcharged while in the docking station?  In the future, is it feasible to simply remove the battery before inserting it into the docking station so that this won't continue to occur? Thank you. (I did a search of the community's knowledgebase, but didn't find anything on point.)  

Answer:Power Manager Setting To Preserve Battery Life When Using A Docking Station

Hi,
 
Welcome to Lenovo Community Forums!
 
I?m sorry to hear that battery of your Lenovo ThinkPad X220 had undergone wear and tear and has to be replaced.
 
Capacity of a battery declines as the battery ages, with the number of charge cycles and time at high temperature. Under average usage patterns your battery maintains approximately 70% of its power capacity after the first year of operation.
 
Most laptops today use lithium Ion (Li-ion) batteries. Overcharging Li-ion batteries is not a problem and does not affect the battery life span. These batteries have an internal circuit to stop the charging process at full charge. This is why the Li-ion batteries are more expensive. The only way for the Li-ion battery to overcharge is if the charging system malfunctions, and then the battery will heat up while in the charger. Older laptops use Nickel-cadmium (Ni-Cd) and Nickel Metal Hydride (Ni-MH) batteries. They require more maintenance than Lithium Ion batteries. They must be fully discharged and then fully recharged so that they don't lose battery life.
 
Refer this document to see the tips on how to increase the battery life.
 
Hope this provided enough clarity for your query!
 
Best regards,
Mithun.

Just a quick question. I have an A100-999, the cheapest of three laptops that I have but for me the best. I wasjust wondering where I could find out about average battery life for the long life battery I have just bought.

Answer:Satellie A100-999: What is the battery life time

Hi

Usually all information about the battery should be provided in the user manual which is preinstalled on the notebook.
It?s also very important to know, that the battery life time depends on the notebook usage.
Using heavy performance applications and additional devices like ODD will decrease the battery working time.
So in such case it?s not easy to say the exactly battery life time.
The notebook was delivered with the standard 4000mAh battery. If you want to use the notebook for a longer time you can buy a stronger battery.

Secondly as far as I know this notebook was delivered with a standard 2000mAh battery.

On the Toshiba page under Option & Accessories I have found a compatible battery pack 8 cell, 4300mAh part number: PA3420U-1BRS

This battery should support a longer life time as the battery 2000mAh.

By the way; such batteries you can purchase from the ASP in your country

I used to have an M2 which had a battery life of around 3hr 45. Last Jan I got an M3, and was surprised it was only 1hr 30 running just Word and a low memory music program. Closing the screen and running only the music program pushed it up to 1hr45. I'd assumed it was because it had a faster cpu etc. but two of my friends also had Toshibas and they thought it was a battery issue.
So what's the battery life of a 1.83GHZ M3 supposed to be?

Answer:Tecra M3: Question about Battery life time

Hi

According to the unit description the battery should run about 3hours.
But the battery working time depends from many different things and this is not a precise value. It???s very important how you use the notebook, which programs are running, how old the battery is, how many devices run together is, etc???
In this case generally it???s not easy to say if the battery has a fault or not.

I recently picked up a Spectre to test drive for a couple weeks. Overall, I like it a lot but there are a couple unpolished elements that bother me, especially that "Calculating" is always displayed instead of a time remaining estimate. A little bit after getting home from the store, I flipped the screen into tablet mode, and it caused unrecoverable screen tearing until force reboot. Next day, I updated Windows to latest build, hoping it'd solve the display driver issue (so far so good, fingers crossed). But after the update it seems to be stuck "Calculating" (if that is indeed what it's doing). Some other posts on this forum seem to suggest that HP removed the feature. Can I expect this to be patched in the future, or is there a workaround? Not looking for a third party application... as others have said, even just disappearing the "Calculating" would begrudingly satisfy me. I guess it's really an aesthetic gripe, yet it will never stop bothering me. Between this and the screen tearing, I'm on the fence whether to keep the device or return it and wait for a skylate macbook pro. If anyone could elucidate me to a known workaround, or confirmation from HP that this will be fixed, I would greatly appreciate it!

Hi,
I'm looking to buy a tablet PC - was having a look at the Portege M400 and Tecra T7 models. Although the battery life would be tolerable, I guess it would depend on how you've set up the computer and how you use it - and I would definitely prefer a safety margin of longer than 5 hours (3 on the tecra). Do these models have the option to swap a new battery pack in and out easily, or to install a second battery to expand the life?

thanks,
Jonathan

Anybody any idea about how long the 1812 LiOn battery of a HP R707 camera should last ?
What are the indications for such a battery to become 'end of live' ?

Yesterday , the battery apparently wouldn't load beyond 3.4 volt.
The camera stayed 'dead' ofcourse.
A second load-attempt gave me 4.3 volts.
And now the camera appears to be function as usual.

The R707 is about 2 years , I took about 4000 pictures up till now.

I thought the lead had come loose so I let it charge again and confirmed it had the charge icon. When I took out the lead 30 mins later it had even less charge.
I thought the phone might just be going screwy so I did a soft reset (held volume down and power until the screen went off, and then the phone vibrated and reset). When the phone came back to life, it had 100% power.

Should I leave the laptop always connected on the charger power cord, no matter if it has full battery or not? Should I always let the battery drop to 10% and then charge it up to 100% and then remove the cord? Or should I do that from time to time and not every day?

Despite the manufacturer's claim of 7 hours battery life on my Lenovo Ideapad 320S-14IKB - 81BN (S/N: MP1CHQTJ), I only get around 3-4 hours. This is with light usage, Reddit, a little bit of youtube etc. CPU usage was mostly around 0-5% the entire time. This was with the max CPU state in power settings reduced from 100% to 85%. However, I do have the screen at 100% brightness. As a different test, I tried doing (almost) nothing (apart from keeping the screen bright), and got 6 hours out of the battery. Is there a simple solution to increase this? It's only a 30 Wh battery (2 cell). Maybe in the future, a 60 Wh (4 cell?) one will come out for this model?

Hi guys,

I have a Satellite M105 and I think Im not getting good battery life out of it. I've had the machine for 1 month and I can get barely 1:50 mins on battery power, with minimum brightness and wifi on, just surfing the web and listening to mp3s. Is this the expected performance for this machine type?

It has a 1.8 Core Duo, 1 Gb RAM, 80 gb HD, x1300 ATI 14'' Any clues? I use the "long life" power saver scheme from Toshiba application. My battery wasn't affected by Toshiba voluntary exchange action.

Thanks

Answer:Satellite M105-SP381: short battery life time - about 1:50 mins

HI Juan,

Different parts of you notebook will use power at higher or lower rates. Generally any component with a mechanical action (your hard drive, optical drive, Floppy drive etc) will use somewhat more power than the CPU, RAM etc.

The effect of this is to drain the battery faster if the hard drive or optical drive is in use. So typically you would expect to get longer battery life if you were using an application such as Word or Excel where there is minimal hard drive activity unless you are constantly saving or loading documents.

In your case the playing of MP3 files will need to constantly load data from the hard drive (albeit cached to reduce the number of accesses) while you internet browsing is constantly writing pages to your Temporary Internet folder (as well as accessing your anti-virus database). All this hard drive activity will mean that the hard drive is never allowed to spin down and so will need to use battery power.

As long as you follow the usual recommendations for optimising your battery (allow it to discharge fully from time to time) I think the time you are actually getting is reasonable for the type of activity you are performing.

But I have disconnected the AC adaptor from the notebook and the little power pack icon appears in the task bar. Then I wait till the power goes down to 98-97 % and go with my cursor above the icon. Then the time displays in percent, hours and minutes.

Hi
Anyone had this issue?

My battery indicator (Windows and also the Toshiba PM) don't show the remaining battey life in minute but only in percentage.
is it correct or there are some strage settings in power setting menu?

Thanks

Answer:NB200 - Battery indicator shows only battery life in percentage

Mine does the same, thats just how it is in XP. But I believe the Vista power saver shows the remaining time.

I think you will need to download a battery utility from the Internet to display the remaining time.

My old T42 had an option to only start recharging the battery once it fell below a specifiable threshold - like 75%, using the battery maximizer tool. This reduces the number or cycles on the battery, and extends life if you frequently unplug your computer for only a few minutes at a time. I can't seem to find the same option in the lenovo energy management application. HAs anybody else seen, or know of a way to achieve this?

Hi,

Even though I don't own an IdeaPad, but still I'm certain such an option doesn't exist on these consumer note/netbooks, sorry.

Hope this answers your question.

Hi guys,I am very happy user of Lenovo T520. I have upgraded to Intel 520 SSD disk and ram to crucial 2x4GB DDR3 and laptop is performing very well ! When I bought my T520, I bought one replacement battery- 9 cell battery(laptop came with 6-cell). I have used it about 10-30 times only and kept it always only 80% charged in cool place(actually at room temperature 22C approx). After one year of no-usage I wanted to start using this replacement battery again. I am very disappointed and confused. I have inserted my 9-cell battery with only 20 charging cycles and it has very low capacity and runtime. Please help me?

Hey there,
Yes you read it correctly: I have just received mine, which I purchased because of battery life and overheating and fan noise issues on the Dell XPS 13 i7 7th gen. The 8th gen was supposed to have solved all the issues the previous version was plagued with...
Well... I unboxed it, loaded all of my softwares, installed all the WIndows updates, Dell drivers, you name it. Charged it and started using it. When I unplugged the power cord, first estimate was 4hrs on the Windows battery indicator. Then I installed BatteryBar to have a more reliable estimator. Same.
Later on, I discovered a very strong and very loud fan. Unsurprisingly, the underneath was burning hot.
Got the support team on the phone, whilst I was talking with them, the fan kicked in and I even could give them a glimpse of how loud that was over the phone.
Has any of the lucky owners of the XPS 13 i7 8th gen come across similar issues? 
Sometimes, I am just baffled by the world there is between the promise and the reality....

Answer:XPS 13 8th gen i7 16GB RAM QHD+ Battery Issues 4hrs battery life tops

A brand new system may have an unusually high level of background tasks running simultaneously, such as Windows and other applications checking for and downloading updates, Windows monitoring your usage to optimize technologies such as PreFetch for your usage patterns, etc.  You might want to conduct a battery test after things have settled in a bit more.  The QHD+ display takes 2-3 hours off of the expected battery life, but you should still get 7-8 hours under normal use.  Then again, if you're heavy on WiFi and max out display brightness, you'll get less than that.  The fact that the fans are kicking on also suggests there's an unusually high level of background activity running, so check Task Manager to see if you can find out what's responsible for that.

Hi There!Some Questions:1) Is the CPU of the Z510 on a socket so I could upgrade it?I saw a dissambling video, that looked like you could do that.And if one can do that: If you place a i7 on that board will the cooler be strong enough and is the battery able to keep up with the power needed from that i7?And if I'd go totally crazy and replace the i5 4200, upgrade that thing to 16gb ram and change the hard drive to an ssd: Will the battery just vaporize? SO: Is it possible to upgrade the 4cell battery installed in my z510? Thanks for your responses! Regards from Germany,Ruforion

My new X1 is great for crunching through data but the power consumption seems very high at idle or when I am doing simple tasks. I have BIOS version 1.27 (released 21/Oct/2011) and Power Manager 3.62 I have used Power Manager to set Power Use to "High energy savings". However, the power used is always >20W and usually around 25-27W. This results in excessive heat (so the fan goes at 4500rpm all the time) and the battery is lasting less than 1 hour if I give a Powerpoint presentation (no movies). Also, the Power Manager shows GPU at 100% all of the time - is this normal or might it be a cause of increased power requirements? I have tried all the solutions to fan noise in this thread:http://forums.lenovo.com/t5/X-Series-ThinkPad-Laptops/x1-fan-Noise/td-p/469001 I have tried setting all power settings to maximise battery life in Windows 7 and then also in Power Manager but to no avail. Please help! What are the ormal power requirements and GPU% at idle?













Solved!

Go to Solution.

Answer:X1 - high power consumption (>20W), GPU 100% all the time, short battery life, loud fan-noise

Check Task Manager to see if there's anything running that is using CPU.As far as I know, there aren't any tools for determining which program is using the integrated GPU. You may try ending services one at a time.

Hi all- I've had my X201T with core i7/2.13GHz, 4GB RAM and 8-cell battery for around 2 months now, and I'm only seeing about 2 hours of battery life before I need to plug-in. I'm running Windows 7 x64 with power options set to "Energy Saver." Is this normal/expected battery life for this configuration? Thanks,Darren David

Answer:Poor battery life on new x201T w/ 8-cell battery

That's not very good. My 4 cell battery gets 2.5 - 3 hours with typical use (wifi on, OneNote, firefox, screen backlight set to 9).My 8 cell battery gets around 6 hours under the same conditions. Video playback can kill those numbers though.

So I reinstalled Vista the other day, and even before that a bit, my battery life was simply terrible. At one time, I was able to get 5 hours maximum. Now, I can (at max) get 2 hours and 15 minutes out of a 9 cell battery. There was a previous topic on this forum, but like many other topics in the Lenovo forums, the topic was deleted. Nearly everything that I've searched for regarding problems with my thinkpad, I have found a topic that linked here, but was since deleted. Very annoying.   So, I have power manager 2.41a. The battery is correctly listed,  (86 Wh Li-Ion). I powercycled it one night, and it changed to 3 hours, but it went back down to 2. I should be getting at least 5, but I've heard reports of people getting 10 hours. I'm no where near that! I'm on power saver setting, and my brightness is at about half. I have all the latest drivers, System Update didn't return anything.  Also, my switchable graphics has stopped working, as it has with plenty of other people. Any word on when a fix for this will be out? It's disappointing to spend $1400 on a laptop, only to have key features stop working. My first experience with Lenovo has not been a good one so far. I thought these things were supposed to be rock solid? That's why I bought it... the keyboard on this one sucks, it's matte instead of rubberized. It's plastic everywhere.... Why spend a premium on something that gets me the quality of an HP or a Dell? Why not spend half the price? &n... Read more

Answer:T400 Battery life very poor. 9 cell battery.

Okay, a couple of things. First to address your battery life. If you are using the latest ATI Switchable graphics drivers then do this: Start -> Run -> type 'MS Config' hit enter. Go to the start up tab and uncheck the following:  igfxpers.exe; igfxtray. For whatever reason, the new ATI switchable graphics driver when on integrated mode hangs the processor causing it to use 50% of the CPU resources. I found my power usage went from 14-16 watt draw back to 8-9w draw. Next for the switchable graphicsdo this: Lenovo just released Power Manager 2 on 1.5.09. So far, I didn't see it available on the Auto Update utility but I found it when browsing the downloads page. So me being OCD about having the latest versions of software/drivers, I decided to download it. After the install, I found that my switchable graphics wasn't in the left click menu as it always has been. I right clicked and did not see it there either. Remembering what I did for the clean install (I went back to factory install), I did the following steps.Restart computer -> go into BIOS and select Discrete graphics only. Let windows start and re-install the drivers. Did another restart to ensure functionality. Then I went back to the BIOS and selected Integrated only. I let windows start, and again it had to re-install the drivers. Once this was done, I entered the BIOS again and put the display to OS detect function and booted windows normally. Thinking I had it fixed, I left clicked on t... Read more

When running on the battery, at the start it suggests some 3 hours of life with 100%, but after less than an hour the system suddenly goes into standby.

I get no "low level" warning any more. The Toshiba Power Saver actions are set up to alarm at 20% and go to standby at 10%. This matches the settings under control panel / power options.
I tried a new battery but the symptoms are exactly the same.

Any ideas?

Answer:Tecra M2 - battery meter/ battery life problem

Nothing immediately springs to mind, but I have a few questions which may help to elicit more information:

- Do you need to plug the M2 in to the charger to make it come out of Standby?
- What happens when you come out of Standby? Does it indicate near 0% of some other value?
- Does it recover from Standby or has it lost any BIOS settings (e.g.) wrong timedate?

Might be worth checking to see if you did anything prior to the problem which may be a factor.

My X1 is about a month and a half old: 1. Battery life on a charge appears to be a little under 3 hours without changing the settings it came with. I know there are setting to maximize the time on one charge but for normal factory settings is this time normal? 2. When I check battery Power and Performance it states that the battery is at 85% of its original capacity. To lose so much capacity in just a month and a half seems odd. Is this normal or can this measure vary? All in all I am having a very positive experience with this computer however I am a little concerned with these power readings I am getting. Thanks in advance.

Answer:X1 Battery Life on a charge and Battery Health Questions

hey bbfolgart,1 - since you did not change any setting, the hours of usage in my opinion is about right; though this also depends on the battery you are using as well as other factors such as screen brightness; application that you're using, if the wireless is on, etc. all of this plays a role on the how much power is left for the battery.2. battery going down to 85% capacity is weird. for this try doing a battery gauge reset from the Power Manager.At the same time, do fully charge the battery and then use your unit without the AC adapter until the battery fully discharges.Recharge the battery and do not use it at this time. Once fully charge, use it again without adapter and see how long the battery last and check the capacity as well.while you do all of this, do check on http://support.lenovo.com if there is any updates for the Power Manager software that you are using and update if applicable.

Clocked on various ocassions, from pressing on button (laptop is off and not restarting from hibernation or suspension), to laptop going into hibernation at 2% critical battery level, using the maximum energy saving mode.

This is with wifi on and surfing the web.

Hdd shuts off after 1 min, display brightness at minimum.

Battery was manufactured at least 4 months ago and is the 9 cell official Toshiba unit supplied with the laptop.

Laptop has 2gb memory and the Core 2 Duo T5750 processor, running Vista basic.

Message was edited by: michael_L300

Just want to add that this means the laptop is using approx 18 watts, which seems to be a very reasonable number, given that just the processor has a tdp of 35 watts. These Core 2 Duos with speed stepping really reduce their energy consumption.

By the way, display is 1280x800, and the wireless adapter is the realtek rtl8781lb, not the intel one.

My family, myself are long time Lenovo Thinkpad T users.  I currently have a T 520.  It's fine as it always has been and quite pleased,  but I would now like something much lighter and it has developed a little glitch that doesn't seem reparable.  I will still keep it as a second, back-up laptop.  I just ordered the T460s that is to my liking and right in my price range (got the basic one new from Lenovo for under $800).   But to my dismay and amazement, I keep reading and hearing about lousy battery charge times ranging from 4 to 7 hrs when it is suppose to be at least 10 hrs.  And about all kinds of efforts and ways to increase it with apparently little success.   I have searched several times in this Thinkpad T forum (and elsewhere) on the latest, up to date info and experience regarding the battery and maximizing, extending battery life for the T460s.  I have not found anything beyond around 10/16/16.    As of 2/12/17, I am wondering what battery is now going into T460s, like the one being built for me.   Is it the same as always or something diferent, new, improved? Are T460s users still having the same problems and issues with the length of the battery charge? Has anyone found something, anything that really does maximize, improve or extend T460s battery life? Thanks, Randy

Hi, I recently ordered and started using a T500 with P8600 processor and 9-cell battery (the one sticking out in the back). After adding 2GB extra memory and an Intel x25-m g2 SSD, I started using it with Windows 7. I have been using it for a little more than a week now, and I've noticed that battery life seems quite bad. Granted, I've only run it on battery for a longer period once, and then I got about 3h 10 min running time on battery. This was with graphics switched to intel, optical drive turned off, wlan and 3g-card off, screen dimmed to half, power plan set to power source optimized.Usage was fairly light, editing code inside Visual Studio. Would this be expected running time? It seems quite short to me, considering my old HP nc8430 with T7200 processor (34W TDP) and 7200rpm disk got nearly 5 hours when it was new.. Is there any kind of extended battery available?

I have a 2013 X1 Carbon.  The battery had originally given me 4-5 hours of life on normal settings.  Recently it had gone down to 2 hours, close to 3 if I used power saver mode, dimmed the screen, etc.  So I got a replacement battery -- and it made no difference.  The battery was installed by a service tech, since it's not user-replaceable.  I thought maybe it was a defective battery (or the tech put the old one back in by mistake), so I called, and they sent me another new battery.  SAME THING.  Battery life is still about 2 hours.   I installed all updates and ran a complete virus check (no viruses).  I run a normal amount of programs and nothing crazy - Chrome web browser, MS Office applications, Skype, and a few others.  I can't understand this at all.  Any ideas would be most appreciated!

Answer:Battery life terrible even with replacement battery

BatteryBar Pro helps me monitor how much battery I am using and how much I have left.  I tend to average about 8 watts of drain when I'm using my 2015 X1 which translates into about 6 hours of use with a 50 watt hour battery.  Download it (they have a free version too which is a little more limited in functionality) and that coupled with your Task Manager should help you quite a bit.  Task Manager allows you to sort open programs by how much CPU they are using so you can figure out the offender.  Chrome is a notorious battery suck but I doubt even Chrome could cause the severe drain you are experiencing.

Answer:best battery to give longest battery life?

Assuming that they are all designed to fit your laptop, you need to look at the ratings. Basically, you want the one with the greatest Ah (amp?re-hour) as that should last longest. Although this usually means the battery with the most cells, it doesn't always follow. Check their specifications.

Hi,
I recently bought a new, 3rd party power cord for my Toshiba Satellite L300 from eBay.
Recently I've noticed that my battery stops charging earlier and earlier. At first it stopped at 87%, then 83%, then 80% all in one week. I've had the computer for about a year which seems a bit early for it to start degrading so fast, so could it be the power cord?

The Toshiba cord says Model: PA-1750-29, Input: 100-240V~ 50-60Hz 1.5A, Output: 19V[solid line above a dotted line]3.95A
The 3rd party cord says Model: PA-34671ACA, Input: 100-240V~1.5A 50/60Hz, Output: 19V[solid over dotted]3.95A

If the new cord is harmful to my battery, I can just solder its input plug onto the Toshiba charger (that's the only bit that was broken) but I'd rather not risk breaking two power cords if I don't need to.

Thanks,
Marlon

So I just downloaded OneKey Optimizer for my Lenovo Z50-70 and there's a green battery icon on the lower right corner of my desktop. Sometimes it'll display the battery percentage, but most of the time it'll display the predicted amount of time the battery has left to sustain my laptop. How can I change the program so that it only displays percentage?

Answer:OneKey Optimizer: Showing battery time instead of battery percentage

I'm having the same problem too. My mom has a Yoga 2 13 and for some reason it did not come with OneKey Optimizer already on it. I downloaded it today from Lenovo's website and though some of the options on that app are on my computer but not on her app on hers, it works just fine. However, I can't seem to figure out how to change her battery icon from telling her the approximate time until the battery dies to showing the battery percentage, like it does on mine.Every time she plugs in the charger, though, the battery percentage displays itself on her battery icon, no doubt because it can't exactly tell how long it will take the battery to run out when it is plugged in, but when she unplugs the charger cord, it reverts back to showing how many hours and minutes it will last. This is very frustrating to her. I haven't been able to find answers to this question anywhere on the internet, so I hope someone will promptly repost a solution to this problem.

I can't tell if my problem is a battery that has packed up or a faulty charger. The blue "Lenovo" name lights up on the charger when it is plugged into the mains socket but the blue light does not come on on the laptop to the right of the keyboard. Last time I plugged the charger in the battery light adjacent to the keyboad flashed yellow a couple of times. The laptop won't boot up from the battery as there is no charge in it. Should I be able to run the laptop off the charger having removed the battery because I can't.

Hi, When I first got my laptop, I would click on the battary icon in the tray and it would give me a time remaining estimate as well as the percentage.  I have since had to reinstall windows 8.1 and no longer have the battery time remaining estimate, just the percentage.  I have installed all the latest drivers from the support site and everything works fine except for that. I have tried every version of the BIOS available on the support site and reinstalled serveral times.  I also tried running a battery check which came back fine.  Any idea on how to fix this? Thanks.

Answer:No Battery Time Remaining when clicking on battery icon in T...

Hello tm200 The Battery Time Remaining information has been removed from BIOS F.11. The battery time estimator basically looking at what you?re doing right now and give an estimated remaining time. It was common for the readout to go from 8 hours to 16 hours in a matter of minutes. This might cause more customer confusion than it would solve. The trend of mobile devices intended last for whole day is try not to estimate their battery life. For example, iPhones, iPads, Android phones, tablets, etc. all don?t try to estimate. They might give insight into your past usage, but they won?t try to project the future.  ThanksWayne

Greetings to the lenovo community, I just bought a lenovo ThinkPad T430s 2352-CTO laptop, and before I boot it for the first time, I want to make sure to know the exact proper care to ensure the best optimization of the battery's lifespan (depending on several power consumption user profiles).I have read through the documentation given with the laptop, as well as the Hardware Maintenance Guide and User Guide, and the following articles http://forums.lenovo.com/t5/IdeaPad-Y-and-U-series-Laptops/Optimizing-battery-run-time-and-battery-l..., http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/How-does-battery-charge-work-ThinkPad-T430s... and http://forums.lenovo.com/t5/Welcome-FAQs-Knowledge-Base/How-can-I-increase-battery-life-ThinkPad/ta-....While the Internet articles do tackle the issue, I believe these are not sufficient.I would like to have the official information regarding:1. First charge cycles (what to do for the first charges in order to get the maximum out of your battery)2. Max/Min Charge % for maximum discharge cycles3. Calibration cycles and the interval between each of them4. The possibility of using the laptop while charging with AC adapter (if it can do any damage to the battery)5. The possibility of letting the laptop connected to power source after the maximal charge setted has been reached.6. The possibility of storing away the battery and only using AC adapterThanks for sharing your knowledge,Best regards,ph423

Hi, I have had my T430 since August of 2012 at the start of college. I am currently running windows 8.1 pro and I recently just noticed my battery life issues and after installing lenovo settings I discovered that my battery's capacity is at 27% of the original capacity. The battery life is really bad, e.g. it says 15 minutes remaining at 25% on POWER SAVER mode.  I have google this and it said to "reset my battery" but unfortunately 8.1 Lenovo power manager doesn't have that feature.  I am just wondering if anyone had any suggestions for what to do?  Will I just have to get a new battery?

you would have to have a pre-Windows 8 OS to gain that crucial battery reset function. This is one reason why i dislike running Win 8 on ThinkPad.

Hello,
A week or two ago, I started seeing a pop-up appear on my Inspiron screen (I run Windows 8). The pop-up said that the AC adapter was not recognized, and therefore, the battery would not charge. It was the same 65W adapter that came with the laptop. I hit F2 at startup to check the BIOS, and it said the adapter wasn't recognized. I decided to order a new adapter. While I waited for it to arrive, the battery gradually drained down, but the laptop continued to work while plugged in.
The new adapter came today, an official Dell adapter. I plugged it in... Same error message. Adapter not recognized.
I ran a check on the battery; the system says the battery is fine. I pulled the battery, and the laptop still worked via the adapter. I jiggled and checked all the connections. Couldn't find an issue and couldn't make it work.
I checked the BIOS version and date, and it's from 2013. Time for an update! I downloaded the latest version, but here's the problem: It won't install without the battery sitting at at least a 10% charge. The battery, of course, won't charge with either adapter (it's reading at 1% now). So I can't update the BIOS without some battery life, but I can't make it recognize the adapter and charge the battery without the updated BIOS (assuming that's even the problem, but I'm hopeful that's all it is).
If anyone has any suggestions for how I might make this work, I would very much appreciate it! Thank you!!!

Answer:Catch-22: No BIOS updated without battery, no battery life without BIOS update...

Please list Dell model number and version of windows. Ex: Dell Inspiron 3543, windows 10
If you don't know, type msinfo32 onto the search box, and then look for System model.....
In the meantime, please check the USB port, where the AC adapter is plugged into system, is loose. You could also wiggle the Adapter's end while checking it in the BIOS to see if the Adapter's type appears.

To all owners of X1 Carbon 2017 (5th gen).I read all of those reviews where people are impressed by 10+ hours of battery life (15,5h advertised), but I can't really figure out how....!? First time I tested was a normal working day - Firefox (a lot of Flash it must be said), Outlook, Word, Excel, Adobe Acrobat. Nothing really heavy, no peripherals except Bluetooth mouse. Brightness dimmed 1 level below the ideal. It lasted for about 4 hours! I windows's list of apps affecting battery life, Firefox was on 1st place with 32-35% Second attempt - same set of tasks, however less Firefox (no flash) - 7 hours. Now in the middle of a 3rd attempt (using Opera this time) - battery time remaining indication goes over 10h only when I completely stop using the laptop Not many apps running in the background either (Dropbox, Skype...) So my question - do you guys get more than 10h of battery life and HOW? Do you enable "Battery Stretch"? How actively do you use it and for what?

Answer:Battery#2 not present and the time of battery is lowered to ...

That model can use a "battery slice" that hooks onto the docking port on the bottom and if installed that is battery #2. They are very rare but you can occasionally find them on eBay. When new if you have that thing and a regular battery you can get 8-10 hours of battery life. Since you do not have one, you have no battery #2. How old is the other battery? They do not last forever and eventually need replacement.

Hi, I have Lenovo ThinkPad Edge E330. few months ago I have got a few messages like "Battery Error" (I don't remember the exact text). From that time nothing changed with battery run time, if I remember well. However ,after some time the battery suddenly went from 5ish hours run time to one hour or less. I would guess the problem could be something like this https://support.lenovo.com/us/en/documents/ht001086 but I haven't find any reliable tool from Lenovo to check the battery. Lenovo solution displays "Health: Fair" in the battery status tab. I have also tried to update battery firmware (http://support.lenovo.com/us/en/downloads/ds001322), but it didn't help. My Notebook is still in warranty.

Hello potential problem solver,The battery seems to be rather... well... underpreforming. I get 2, maybe 2 hours and 15 minutes out of a single charge, with the screen brightnes on 30% and in powersaving mode. Now I know the fabled 5 hr battery life they claimed it had would be a bit far fetched. But I can't help but think there's a problem here. So naturally I've looked up possible ways to fix this, e.g. recalibrating the battery guage with lenovo's built in software. Sadly, this did nothing. With the battery life as bad as it is now, the "time remaining" counter plummets even farther into the dark depths of oblivion (credit for colourfull writing) when launching a game. Also, it won't use the dedicated gpu, but I think the battery is a more pressing matter atm.Regards, Thomas

Hello  I have a Lenovo y40-80 laptop, out of warranty since 8 days, and I think the battery is either dead or faulty. I'm still hoping to find a way to fix my problem with your help. Recap of the whole thing:1) Battery is working perfectly, keeping its charge and giving me a couple of hours (4-6h per charge) after 1 year. 2) Warranty ends on october 31st. I thought "no need for an extension, what could happen?" 3) November 4, I take my computer to class and I'm suprise to see it's stuck at 100%. Then my computer shut down after 15 minutes (was still at 100%). 4) Plug my charger and start it right away. The gauge is now showing 0% and charging, but it's not as it stuck again at 0%. 5) Since then, either the battery level shows 100% when charged until I unplug it and it shut down fast OR it stays at 0% when I charge it and sometimes randomly goes back to 100%. I've been searching for a solution for a couple of days, trying to uninstall the Energy manager and the ACPI pilot, but it is still defective. Ironically, my warranty has been expired only for a couple of days and I thought about purchasing an extended warranty. Would it be possible and would it covers for my battery? Thanks a lot!

Hi all! As written in the topic I have a huge problem with the run-on-battery-management of my X301-System + Windows 7 SP1. I replaced the optical drive with a secondary battery (ultrabay). Both batteries were identified by the system and charged to 100%.But when I run the system on battery, the system only uses the second battery. So if it runs down, the system turns into suspend/hibernate mode even if the primary battery is charged to 100%.Why doesn't the system switch automatically to the primary battery, when the second one is empty? As long as the second battery is down, the system also won't start/resume from the suspend/hibernate mode. Does anyone know this problem? Is there a known solution for that problem?

I must say this has been a surprisingly pleasent experience. I am about 2 months shy of the 18 month cutoff and the battery died 2 days ago. No warnings or anything. Since I am travelling with the thing I immidiately bought a replacement on Ebay for $60. This morning I saw the battery recall sticky and called in. The Rep. was very nice and was able to pull up the correct info in about 4 minutes. He asked a bunch of questions, got my address and the new battery is being shipped in a couple business days. And now I have 2 batteries on the way. So I have a FYI and a question Does anyone know what the shelf life of a Lithum Ion battery is? I am planning on using just 1 of the batteries and keep the other for later. Please let me know if you have any suggestions. The one I bought cannot be sent back. FYIThe Rep did not have any information on what the problem with the batteries was, but indicated that the would be sending me a return shipping label to send the faulty one back. A good thing since these batteries have to be disposed on a certain way.

Answer:Faulty Battery Experience

if you keep the battery at 40 to 50 percent charge level, it should be okay to store for 2 years, but my suggestion is you use them interchangeably. Some of the batteries made by Sanyo and Sony have contamination in them that shortens their lifetime from 2-3 years to around 10-12 months, in extreme cases the battery may overheat to an extent that it self detonates as in some earlier Sony batteries.

I have an x61 thinkpad. I've been using it for 15 months, so it's out of warranty (and the batteries don't get extended warranties anyway, or so the tech help person told me). The battery died today. I just got off the plane after using the laptop for about 2 hours. I came home to charge it up and found the battery light to be orange and blinking when plugged in. I unplugged my laptop and it died, completely ignoring the battery which should've still had some change in it from the plane (since it said 50 min left when I put it in suspension, and it only took me 30 min to get home... so there's no way it was all drained on the way). I called the tech people and connected after about 40 min. He said that it's quite common for batteries to die spontaneously, from 2+ hrs of charge to 0. I myself find that quite hard to believe, as I have owned several laptops (a mac, 2 toshibas, and 1 compaq) where the batteries dwindled to under 10 min even when fully charged. But NONE of them died completely and suddenly like this. Especially when there should've still been charge left on the battery. I have also checked the recalled batteries, which did not include this battery (42T4506), even though symptoms seem the same. I'm wondering how many other people have had the same problem with this battery? Have you all just given up and bought a new battery? Given up and bought another laptop that's a different brand? (My toshibas had short battery lives, but at least the batt... Read more

Answer:Faulty 42T4506 (8-cell) battery?

The newer battery cells have tiny engineering tolerances, the battery manufacturers have optimised the battery cells in such a way that minimises explosion and overheating (a sort of built-in safety feature) and also closed the tolerance gap in such a way that battery cell gives sudden degradation instead of gradual degradation of the older cells. The Lithium ion cells are considered a commodity now, no longer a high tech product, like it was several years ago. This is bit like the digital tv signal and analogue tv signal. The digital tv signal doesn't gradually detereoriate in signal quality like analogue with their visual artifacts, when you reach a certain distance or quality limit, the signal just suddenly disappears, where as the analogue signal would still be visible, even though the quality is very bad.

My battery (FRU: 42t4957) is stuck at 2% and refuses to charge:I kept it at 40-50% most of the time by changing battery threshold. Total cycle count was about 80 (84 now) first use date 2013-03.On Saturday I tried to run a "discharge-charge-discharge-charge" cycle (by watching some movies) to reset the gauge of my battery. During 2nd discharge my laptop hibernated due to low charge much earlier than expected, when I turned it on it showed that the max capacity is 28 Wh and the battery is in the "poor" condition.I tried to perform automatic gauge reset but didn't get much (29 Wh). I updated power manager and performed another automatic reset which failed too.So I tried to make a manual reset and left my laptop paying a movie for a night. On Monday I plugged my AC adapter in but found out that the battery won't charge: "a battery error has occurred the battery cannot be charged".I cleared residual capacitance by pushing the power button several times and reset the BIOS to defaults but got nothing.If this problem can't be sold I would like to know the reason of it to avoid such things in the future. While googling this forum I met contradictory opinions on battery reset: ones say that it's extremely harmful because battery "doesn't like" to be discharged to 0%, others say its harmless.

After my friend's laptop wouldn't run on battery power OR charge the battery I tried many "fixes."
 
Shockingly none worked that I found.
 
Only one thing worked for me to my surprise.
 
A last ditch effort was to open up the laptop (sony pcg-81114L) and disconnect the cmos battery for a few minutes to reset the CMOS.
 
To my surprise, when powered on, the battery instantly showed it was charging AND when removing the power plug the battery POWERS the laptop now! (and I'd thought I was wasting my time.)
 
Worked with an off brand battery also.
 
Many times this has saved many computers that have odd "unsolvable" things wrong with them.
 
Surely someone else has done this also but I haven't seen it posted anywhere to my knowledge.
 
Thank GOD for bringing the idea to remembrance!

Hello all, Just got a new XPS L521X with 8 pre installed but the battery life isn't that great. I am getting mixed responses about if this is the normal battery life (about 25% an hour). I put "powercfg /energy" in CMD and I got this back:

Question: Battery Life

In the old days I seem to remember that batteries had a memory in that if you did not discharge them totally before recharging then it progressively lost some of its 'life'. Indeed this seems to have happened to my son's laptop in that he has it on the mains most of the time and now without that it only has a life of 30 minutes.However, does that really still happen or is it more likely it is a faulty battery?Thanks in advance

Answer:Battery Life

How old is the Laptop? because unless it is old that should not happen as modern batteries are not NiCad any more and they are the one's that had memory, mine does the same as your son's but it is 2.5yrs old.
