Battery life and charge-cycle. Background light life-cycle.

Question: Battery life and charge-cycle. Background light life-cycle.

1.Prolonging battery life-cycle by the "do not charge when battery charge is above nn% which by default is 96%. How about setting it manually to much smaller value. 50%-60%. Would that prolong batterly life-cycle? (When I dont want to charge the battery)2. All parameters set to small values for using as little energy as possible for extending the time when nly battery power is available: The temperature is still (far too) high underneath where (center-center) the ventilation gaps are. How come? The only process take CPU-power is logmon.exe from IBM/Lenovo...3. Logmon.exe is alway running at about 15% CPU... How can I change that?4 Is the screen background light gas-filled? If so, will the life-cycle shorten if it turns on/off to frequently? (Light timeout value to low)Thank you IBM/Lenovo for this site.Regards,

Preferred Solution: Battery life and charge-cycle. Background light life-cycle.

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: Battery life and charge-cycle. Background light life-cycle.

1) See and follow the hints and tips of the Battery University2) Look at the Z60m part list or into the HMM in order to detect which parts/components are sitting there, this will give you some hint what parts might get heated up a lot near the thermal device.3) AFAIK logmon.exe is part of or belongs to ThinkVantage rescues & recovery. - If it runs as a service on your OS, then you can disable that service or maybe you can just change the scheduling times for that monitor service inside r & r. A look into the r & r manual, which can be found on Lenovo's website, might can tell you more about this.4) Look for yourself here, CCFL backlights for notebooks have usually a life time of 15.000 till 30.000 hours. Yes in practise the life-time will shorten, but this is common for all electronic devices over time.

I am using a Dell XPS 9550 primarily as a desktop.  By that, I mean, it is pretty much always plugged in and I rarely need to move it.  In order to keep from totally burning out the battery, I have completely pulled the battery out and just use the laptop on AC power.  When I need to travel, I'll put the battery in.  With the number of screws needed to do this every time, it is super inconvenient, so I wanted to know if there was a better alternative.
The BIOS battery options include a "Primarily AC Use" setting that says it is for users who mainly use the laptop plugged in.  Does anyone know how this actually works?  If I am on AC power with the battery charging and it hits 100%, what happens to the battery if I continue to leave the thing plugged in for an extended session, say 6 hours?  Is it just constantly running down to 99% and then charging back up to 100%?  And how does the AC Use option change this?
It would be nice if there was simply a way to disable battery charging completely without pulling the thing out, but if there is some good alternative, i would love to hear about it.
Thanks!

When support for DOS 6 was ended by Microsoft, we who wanted to continue using it, could. The same for Windows 3.1, Windows 95, Windows 98, Windows ME and Windows 2000. As long as we can find compatible hardware, we who want to use it can continue indefinitely.

But there is a worry I have about Windows XP; it requires activation. When Microsoft chooses to cease support for Windows XP, what is to keep them from simply refusing to activate it?

Is there anything in the license agreement that says we are guaranteed the use of it after its Microsoft-defined life cycle ends?

hi here, i have a new laptop battery and was wondering what is the first first charge cycle to optimise battery life. i have read that you plug it in , disconnect charge and completely empty it before charging. Alternatively i have read to fully charge before hand. the actual instructions a re clearly a translation and tricky to comprehend. Whats the normal go for a new battery? Cheers

Answer:new laptop battery charge cycle

I would suggest you put the laptop on charge until the indicator shows 100% and then leave it for a further hour; this is similar to recommendations made for digital camera batteries. There is a very good site for battery information which may also be of interest.

I have been getting this weird charge discharge cycle on my Pavilion 15. I pretty much have my Laptop always plugged in. A couple of days ago it shutdown in a blink even though it was at full charge. Then it would'nt start even when I pressed the power ON button. It started after I took out the battery and put it back in. Ever since then its trapped in a cycle where it always shows "2 mins to charge" in the notification icon and a certain percentage. Then when the percentage hits 100 it stops charging and instead discharges gradually even though it's plugged in. When it hits 0% it shutsdown again and won't start till I take the battery off.  Can someone tell me whether this is a problem with the battery or the charger and how can I fix this. Thanks

 Ok weird problem - I have a T42 with a "real" IBM battery running XP and latest version of power manager s/w  V1.85 . I can run the battery maint.  test cycle and the T42 successfuly (or so it claims) runs the battery down and then charges it back up and reports that it is in good condition.  But when I unplug the 120V charger the laptop immediately shuts off, and will not run from battery. The contacts on the battery and in the laptop seem to be in fine shape.  I have tried another battery that works fine in a different T42 but I still have the same problem. When problem started the BIOS/controller code were downlevel, but I have now updated to the latest:    BIOS  - V3.23   Embedded controller code V3.04   Then reset BIOS to default settings But ... problem remains. Thanks for any assistance!

I've bought this m/c secondhand (production date 8th Feb 2005) and wondering if I should invest in a replacement battery. After a full charge it shows a duration of about 1hr 20min but this decreases very quickly with use and don't think I get more than an hour operation out of it.

The battery is an 8 cell Li-ion 14.8V 4300 mAh

Should/can I expect something better?

Answer:Battery Life on one charge Satellite Pro A60

Hi

I think it?s not easy to say how long the notebook should runs only with a battery.
The battery working time depends on the notebook usage. You know, it depends on the applications and devices which run on the notebook. Heavy software like games or videos needs more graphic performance as the Office software. If the drive or HDD spins all the time so the battery performance will also decreases much faster.

But you could also try to buy a battery witch better performance. On the Toshiba page I have found a battery for Satellite Pro A60 and it?s a Battery Pack Li-Ion, 9 cell, 4500mAh. As you can see this battery supports 9 cell and 4500mAh and should be better as your first old battery.

Hi, I have my Z60m for about 3 years now. For this time I had two batteries - 6 cell. I didn't notice anything bad about the original one - I used not much power management and didn't remember seeing it to degrade quickly. However one day it shut off. I checked and it appeared to be affected by the battery recall program. I applied for a replacement and I received it very quickly - a few days later. So, a year and a few months now after I started using the new battery it is almost dead. I use it at a bare minimum - most of the time I am plugged into AC and my power management is adjusted so that the battery starts charging when below 65% and stops at 90%. But it just slowly dies. It was at less than 80% its original capacity when just over 10 cycles. I never noticed the battery getting too hot - it was cold even when the system was under load and the chasis was heated. Now Battery Information displays cycle count as 29. And its capacity is 22% compared to the original. Some of the cycles are me using battery reset checking how much of the capacity I have lost. Today I have tested for how long it would keep the system running - on Maximum Battery Life power plan and no system load at all. It was 15 minutes flat - although the battery meter showed 40 remaining minutes at the start. At about 60% of the battery remaining, the orange light started to blink and the system hybernated. After I connected to AC it showed 5% charge. So is this my bad luck getting a crappy... Read more

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.

Hi,=I got my G50-70 laptop less than a month ago, and I liked the fact that it had long batttery life which could surivve 4 hr powercuts. I was happy I could use 6+- hours in WordAs I had previous experience with other notebooks (not lenova) which didn't retain their battery life, due to being plugged in the whole time, I decided to be extra careful about how I use this notebook in order to keep its long battery life.Therefore I hardly used it when plugged, instead using it like a tablet - charging and then using wihtout plugged in.last week, I used it for about 5 hours on word, without charging (albeit with a low brightness screen) and it survived with battery to spare.However, over the weekend, i by mistake left it in to charge for 24 hours and when I use it since than.. it only gives me 4 hours. Could new apps installed be the cause for it?I am wondering how to solve it? Also, what is the Lenova verdict regarding the extend life of battery verdict? i read the atricle and the only new thing I gained was conservation modde. Other than that- does using the laptop when plugged in ruin battery (if conservation mode is on?). Is it better to use the laptop unplugged  when watching videos and skyping Or should I rather have it plugged in on conservation mode? Another thing.. my ntoebook does not always give me how many hours I have left -  it will just say 60%. How do I get the exact number?RegardsCK

hi chach613,
 
Welcome to the Forums.
 
Regarding your questions:
1. It's possible that the apps that you've installed are running in the background and are eating up system resources. To check, try the following:
a. Open Command Prompt as admin (press Winkey+X, choose Command Prompt (Admin))
b. On the command prompt box, type powercfg -energy -output %USERPROFILE%\Desktop\Energy_Report.html and post the energy-report.here or upload it online (e.g., Google drive)
 
More info:
Battery Usage Report - Generate in Windows 8
How to Run a Power Efficiency Diagnostics Report in Windows 7 and Windows 8
 
2. If you'll be using MS Word only, then you should set the power plan to Power Saver and use the unit using low brightness (battery power). If you'll be plugged in most of the time while playing movies, Skype, or running graphics intensive then you should enable Conservation Mode. Once activated, the battery charge will be limitted to 60% and the power source will be routed to the AC adapter (preventing the battery from over charging).
 
3. Can you try to download and install BatteryInfoView to get a rought information on the battery.
 
 
Let me know how it goes.
 
Regards

My problem is almost identical to this thread http://www.techspot.com/vb/topic121358.html
I am putting a new video card (HD 4650) into the system in my sig.
Uninstalled drivers, put new card in, plugged in power supply and the CPU and GPU fans started for 2 to 3 second, than stoped, started again and stopped, they continued to cycle on and off without me ever pressing my cases power button.
I had to put the power cord the get the fans to stop cycling.
Then I removed the video card and the booted the computer using the integrated graphics and everything worked fine.
Is the start up power draw from the video card is to much for my Dell 305w PSU? Maybe the PSU can't supply enough power, which would explain why removing the card fixes the problem.
I tried removing two of my computer's four RAM stick and reinserting the video card, but the fans would still endlessly cycle until I pulled the power cord.

What should I do?
Should I get a new power supply?
I measured the current PSU and it is a weird size:
~3 7/8" tall (9.8 cm)
~5 1/2" long (13.8 cm)
~6" deep / width (14.7 cm)
Voltage and such... 305W
+5V = 22A
+12VA = 18A
+12VB = 18A
-12V = 1A
+3.3V = 17A
+5VSB = 2A
combined max 12VA and 12VB = 22A

I saw this PSU... at newegg
Any help, comments suggestions? Do you think it really is the psu or am I barking up the wrong tree?

Bought two farily expensive OEM PH09 extended life batteries from an authorized HP vendor online eight months ago for a conference. Used each battery twice over the course of four days. One then sat in my laptop unused for a couple months after that, and when I next turned it on, the laptop reported it as "0% available (plugged in, not charging)". I assume it discharged completely, even though the laptop was off or hibernating. Battery reports same condition on friend's ProBook. OEM power supply charges the other battery (and my original battery) fine. On plugging in the power cord, I get a brief orange flash from the charging light above the port, then nothing. Updated the laptop BIOS, no joy. Have deleted the battery items in Device Manager, no joy. Have booted without battery and added, booted with it and removed it, all the combinations, no joy. Installed the HP Support Assistant and ran the battery check and it reports "The battery is functioning correctly, but it has not been charged recently. The battery should be charged completely before removing the AC adapter." Thanks :-). Research suggests some chip in the battery itself has simply "turned off". I asked the vendor for help, they said call HP. Took a long time to reach someone at HP, they said talk to the vendor.

All,I bought my w520 in late October 2011, and have had to travel since then enough to know that 183 cycles is too low. Well, perhaps there is a way they count a "cycle" that affects this. My battery is the unit that extends about 3/4 inch past the back edge; I have forgotten the name/designation. I felt, without any scientific evidence, that I had shorter work sessions on battery during the past several months. I know I receive a better time on Optimus -- I factor that into my expectations. With previous Lenovo ThinkPads I have bought second batteries and will do so soon, I guess, but I was surprised by the count. Thoughts on count accuracy? jonathan7007

Answer:Battery cycle # way too low. Any better way to know?

Hey there jonathan7007,
 
A battery cycle is defined as using and recharging 100% of battery capacity equals one full charge cycle. My understanding of this can be explained with the follow example:
 
I use my machine on battery and it drain down to 40% and I recharge it back 100%. Later on I use the machine again on battery down to 60% and recharge it back to 100%. This, 60% + 40%, equals 1 battery cycle. So 183 cycles may actually be in line depending on how battery heaving you have been, if you bring it close to 0% often, etc..
 
With this battery coming on a year and half old, what is the average battery life your getting at max charge? Does the power manager report the health of the battery as good? It is not unusual to see a decline in available battery's usage without AC over time. However, there are a few knowledgebase articles that are quite handy to take a look at if you are unfamiliar with them:
 
How Can I Increase Battery Life?
How To Maximize Battery Life

Is there anyway to reset the cycle count?

the battery's life isn't related to the battery cycle count, some of my battery died at 90 cycle, while another has 500 cycles on it and still working. There is no reset software for the cycle counts.

HP support assistant says that my battery cycle count is 252/300. My question is ,, how this is calculated ??My laptop is of 9/10 months..What should I do to control the increase rate?How I should charge or discharge the battery ?When the cycle count is exceeds 300 , will the battery work ?Someone please help..thanks in advance..

Answer:Battery Cycle Count

Hi, Normally "A charge cycle means using all of the battery?s power, but that doesn?t necessarily mean a single charge. For example, you could use your notebook for an hour or more one day, using half its charge, and then recharge it fully. If you did the same thing the next day, it would count as one charge cycle, not two, so it may take several days to complete a cycle" Source: https://support.apple.com/en-au/HT201585 (Same for many types of batteries now). The following site will tell you all about batteries:        http://batteryuniversity.com/learn/ Depending on the quality of batteries, you can get over 700 charges or more (that why some machines can get 3 years warranty on batteries) but time between charges will get shorter. Regards.

In my laptop lenovo IBM Thinkpad T60, I have the original battery of news that I cared, always charged and discharged to the end, rarely recharged. Today it has 157 cycles and its condition is poor. Why? Perform Reset did nothing but that does not help you in any way to reset the program cycles of the battery or reduce their number? I have seen with friends on batteries that have more than 200 cycles and the condition is Good, the battery works very nicely. My other hand is charged at 100% and stand about 40min of work, further diminishing the scale of the battery is not evenly but drops to 60%, and suddenly at 1%.

Answer:Battery Condition Poor why, cycle count: 157

Lithium ion batteries can last 300-500 cycles, but there are other factors which effect life: Capacity reduces over time, even if you're not using it, typically over 2-3 years. Keeping them fully charged, and/or at high temperatures accelerates aging. If your laptop is mainly plugged in, they can last as little as 12-18 months. Check Battery University or Wikipedia for more information.

All,Two questions:1. Where is the info found about # of battery cycles? I looked around in System and the ThinkVantage info. I got the answer that Windows Management Instrumentation SW/Info was diasabled or not working ("files may be moved or missing") and I don't know how to fix that without a Vista (SP1) re-install. (Not going to happen unless I have to.) My x61T is a year old and I use the 8-cell battery fairly often. Howevere, I disconnect the battery when I know I will be on AC for a while. I believe that helps with battery life. 2. Are there sources of Lenovo batteries -- not copies -- anywhere beside Lenovo. The Amazon options looked like they might be lower quality and life. I will pony up the [Lenovo-built] $150+shipping way out here if I have to. Thanks, in advance, for thoughts about this.  jonathan7007

I got my new x220 around a weeks ago. I updated all the drivers, upgrades the system to ultimate x64 SP1, slip installed the Intel video driver to 8.15.10.2361 and put in 8gb of G.SKILL ram Everything seemed fine, I ran the PC doctor ram test and it passed everything. Today I was just browsing google using firefox when it suddenly shut down on me and rebooted. Then before it can get to my desktop, it gave me a BSOD (passed too quick to read) and rebooted again. I ran the startup fix and it said can't fix problem. So I booted in safe mode and checked event viewer. All it had was a event 41 telling me the system didn't shut down properly due to crash/power loss/etc. I stayed in safe mode for half and hour and everything seemed ok I was able to boot into windows the next time, but it wasn't long before it gave me another BSOD and shut down. At that time my battery had around 37% and I was on energy saver So I plugged in the power source and it seems to have solved the problem. From the thinkvantage toolbox I ran the memory test again, along with harddrive and video test and it all passed  I live in Canada and I really don't feel like shipping it all the way back so I was hoping to find a solution without resolving to that... thank you!

Answer:x220 BSOD + reboot cycle when on battery

hey Melkorbane,you mentioned about upgrading to Ultimate x64, was this the original OS that came with the machine or was it something else ?And since you added the G.SKill RAM, could you use the original RAM and see if that makes a difference.

Answer:Check battery cycle count on Helix and windows 8.1?

Hi Daemos,
 
Welcome to Lenovo Community Forums!
 
I?m sorry to inform that the Battery Health Mode setting has been removed from Lenovo Settings.  When you install the latest version of the Lenovo Settings Dependency Package, Battery Health Mode will become disabled and the setting will no longer be available to change within Lenovo Settings.
 
It was removed just because it created needless confusion regarding battery charging. Fully charging the battery is totally fine.
 
Hope this clarified your query!
 
Best regards,
Mithun.

Hi everyone. Wondering if anyone can shed some light. I've just successfully replaced a Thinkpad S1 (1st gen) with a genuine, suppose to be a "new" battery that I got from eBay. However, checking the Lenovo Settings app, I see the battery cycle count as 97 times. I was expecting 1 or any number less than 10. Could it be that I got a used battery? Or I have to perform a battery reset (currently in progress) to get the accurate cycle count? Appreciate any inputs. TIA!

However, the machine would still not switch on. I then decided to pull out the multimeter I had lying around and at the charging point on the charger, I found that it was producing the correct 20v. Searching I removed the battery and power supply and held down the power button on the machine, and it is still not switching on, or showing any signs of life =[ Any help would be great before I call out someone out,  Thanks!

This just started happening recently. The power indicator light (near the power plug) does not turn on and Windows does not recognize when the adapter is plugged in; the power icon and cusomized power saving "on battery" behavior reflect that. HOWEVER, the battery does charge. The "lightning bolt" charging light on the front between HDD and system power lights comes on and the battery recharges if not at 100%. Any thoughts on how to troubleshoot this? Is it more likely a Windows or hardware problem? The BIOS does not have the power adapter test mentioned here, and I could not find the software download for the Smart Adapter functionality (this laptop was installed with clean, non-OEM OS, so any OEM software had to be added manually). Thanks in advance,Kyle

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.

Answer:Laptop battery not charging, battery not identified, 0% battery life

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

The night before last, I put my phone on charge whilst I went to sleep and when I woke up in the morning I found that the battery was showing as being in saver mode. 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.
Within 3 hours I was down to about 50% when it had just been sat on the desk, idle, next to me. I turned the phone off and on again, and the battery life was back up to about 98%.

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?

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?

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.

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 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.

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.

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.

Question: Battery Life

When a battery on a laptop loses its battery life, do you usually contribute that to the adapter that charges the battery, or the battery itself? Reason I ask is because i've had my HP dz8000 (or zd) for about 4 years now. It is a desktop replacement and never really had a lot of battery life in the first place. It has a 3.4 intel P4, 2 gig ram, and a 256 mb video card. When i first purchased it i got two batteries, and they both lasted about an hour in a half. As time went on they kind of slowly lost their charge, and were down to about 50 minutes to an hour. Then within a week BOTH batteries died to where the laptop didn't get anymore than 8 minutes (on the best power save setting).

I was going to purchase a new battery, but the suckers run like 160 dollars. Then I got to thinking about how both batteries died at the same time. And how one battery was barely ever used (only switched them out like a handful of times on long trips) and it died at the same time and will only give me 8 minutes.

Okay long story short, i was starting to think it could be the adapter. And since the adapter is hella cheaper I was hoping it would be that. What do you guys think?

Answer:Battery Life

Hello,

No batteries last forever. Every rechargable battery dies after a period of time. Even the little AA ones you use with the Wiimotes or whatever. You will see that after a few years of constant use and recharge they need to be charged more often till they cant work anymore.

I know tha tin the case of the AA batteries this is because of the Acid that is in them starts to degrade over time and not hold the charge for long. I do not know how the laptop batteries work as per the interior. But i would guess it is along those lines.

Plus having the battery in if you are using a wall adapter will help kill the battery faster.

Cheers,
Mak

Question: Bad battery life

After win10 upgrade my laptop stays alive for maybe 1hour but before upgrade i used to work with my laptop for about 5hour. The same problem appeared when I was using Linux, the solution was 'bumblebee'-package, there wasn't a driver for my graphics card (I have an integrated and dedicated card) so it was exhausting the battery.

I don't it's problem with drivers now... at least it would be really weird.

Has someone a similar problem? Have you found a solution?

Answer:Bad battery life

Linux's bumblebee package is what switches between your integrated and NVIDIA graphics cards.

Look for NVIDIA optimus drivers on NVIDIA's website. What's the model of your laptop and the model of your GPUs?

Question: X1 battery life

Any X1 owners care to share their battery status/experience?  I was wondering a bit about my missus X1 showing a max capacity of 33 Wh out of original 38,something, after just a month and 6 cycles. Thats more than 10% down already. As a sidenote, if she unplugs the machine to watch an episode of some series, it will only last power on battery for about 45-60mins. Admitted that is with a bright screen and using the speakers, but still, i was a bit shocked to learn this. When looking it up, it was bragging with about 4-5 hours battery life. I know this is with NOTHING enabled, lowest brightness, no sound and only looking at the desktop without actually moving anything... but... yeah well... Is our battery sick, or is this normal?

Answer:X1 battery life

Down 10% after 1 month/6 cycles? That surely can't be right.For comparison, my X220 with 6 Cell batt is 99% capacity, 56.13Wh out of 56.78Wh, 18 cycles, 6 months old.

Answer:Battery Life

Hi wizkid, Vista is more resource demanding, more heat is generated which causing the fan running in full blast often. Also, there always process working on the back ground such as indexing or defrag as such. So, I guess there is not much you can do about it.

Answer:battery life

That's pretty much what you get here..."anyone". That's me. We don't work for HP for the most part we are just fellow end users who can give advice but have no power to make any kind of financial adjustment or ship any replacement parts to you. But the advice I can give you starts with testing the battery. There is a battery health diagnostic both in the UEFI diagnostic (tap F2 as you power up) and the HP Support Assistant from within running Windows. Try those and report back what it says as far as how the cells of the battery are working. Either the battery itself is defective or you are not really shutting off the laptop and some program or process is continuing to leach power when you think it is off.

Answer:pc battery life

Battery life is not fixed - I've had many motherboards and never had to replace a single battery - a friend had to replace a battery after less than 2 years.The first indication is that the system fails to remember time and date and reverts to the BIOS basic settings on boot-up. If the battery fails, its normally just a matter of replacing it. Some older PC have mobos with the battery soldered into place, but even these CAN be replaced. But the modern ones take watch-type batteries you can pick up from any PC repair shop.

In response to customer reports of unexpected battery gauge behavior on Y40-70 and Y40-80 laptops, Lenovo determined the battery gauge software is performing as expected. The unusual gauge results being reported are a reflection of the battery reaching end of life.
 
Lenovo has released a Service TIP to assist customers with obtaining battery replacements under warranty, or if out of warranty, to find a replacement battery from Lenovo-approved vendors. The Service TIP can be found here: https://support.lenovo.com/us/en/solutions/sf16-I0023
 
The part numbers for Y40-70/80 batteries are:
Y40 SP/A L13M4P01 7.4V48Wh 4cell bty (Y40-70/Y40-80) 121500248

To determine which battery came with your Y40 notebook, instructions for removing the bottom cover can be found in the Hardware Maintenance Manual pdf here. An alternative to opening your system (which does not void warranty) is to search for batteries using the model/product number located on the bottom cover.

Answer:Battery life

Syngonium,
 
Personally, I would recommend keeping the battery in the notebook for several reasons:
 
1) It protects you against data loss if the AC power glitches
2) It ensures the system will run 100% CPU capabilities on demand - some systems will scale the CPU a bit if the battery is removed to ensure adequate power is available to support all USB and other possible connections.  The battery helps the system manage through any peaks in power demand.
 
If you feel that you want to store the battery, I believe the popular recommendation is to store it at about 40% charge level.  Others may have somewhat different recommendations - I'm not sure there is an absolute answer.
 
Best regards,
 
Mark

Answer:Battery life of L20-155

Hi

Well, this is a approximately specification of battery life time.
The battery life time depends on the notebook usage.
For example: how often and how long you use the HDD, optical disc and the floppy disk drive, how you use the optical devices such a Pc card, where you store your programs and data.
Furthermore the closing the display when you are not using the keyboard saves power. Also the enabling standby mode conserves battery power if you are frequently turning the computer off and on.

Please also check the user manual which is preinstalled on your notebook. There you will find a lot of useful information about the battery usage.

Bye

I was just wondering about my laptop battery. Do I want to be sure it is fully dead before plugging it in? Or does it matter? Can I use the battery half way, than plug it in with no harm to the battery life? Thanks in advance.

(Note) My laptop is new, I bought it a few days ago, so it has a modern battery, just in case anyone is wondering.

Answer:Battery Life

Batteries now work on 'cycles' - the number of times the battery can be recharged, which is limited - anywhere between 300 and 2000 times depending on the quality of the battery. If you charge it when the battery level is halfway, then that's another cycle used. This means you've only gotten half the charge, but you've used up a full 'cycle', if you know what I mean. It technically doesn't damage the battery life, but it does mean the battery's life will be used up more quickly.

Keep in mind, I've used my netbook now for over a year without caring how long or when I charge it. I haven't had any problems.

Edit:During the quick bit of research I did for this post, I found that Macbooks have 80% charge after 300 charge cycles. This is less than a year's usage, assuming you use it fully every day...

Answer:Battery Life

Hi jeepchick76, and welcome to the Lenovo User Community!
 
Lithium ion batteries can last 300-500 cycles, but there are other factors which effect life: Capacity reduces over time, even if you're not using it, typically over 2-3 years. Keeping them fully charged, and/or at high temperatures accelerates aging. If your laptop is mainly plugged in, they can last as little as 12-18 months. Check Battery University or Wikipedia for more information.
 
One thing to check is whether your battery is covered by this replacement program:
