T440 Internal Battery issue

Question: T440 Internal Battery issue

I have a T440 laptop that suddenly decided it's having an error with the internal battery that shipped with the system (which is a genuine battery, has not been touched/removed and was working fine until this morning). The error displaying is: "The battery installed is not supported by this system and will not charge. Please replace the battery with the correct Lenovo battery for this system." I updated to the atest BIOS a few weeks ago, have the latest Power Manager and Power Manager driver as of a few days ago. External/removable battery is fine. Any thoughts on how to resolve this, or anyone else having this issue?

Hello, I've just bought a second hand T440, and windows 7 tells me that battery #1 is "missing" (battery #2 is ok).If i take out the external battery while in BIOS or Windows, the computer shuts down, so I believe it's not a driver issue.My BIOS is up to date (2.29), set to default configuration.Do you think it's a hardware issue?Thanks for your helpPierre

Answer:T440 - Internal battery not detected

I think whoever you purchased this second hand laptop off of removed your internal battery. that would just be too **bleep** funny if that were the case. "I don't think it's a driver" LOL no your battery is missing! read the error message agin!  LOL  Hey at least you benefit from the reduced weight! LOL Always buy new or certified refurbished parts

After buying a T440 (not throuh lenovo), I realized that it has capability to hold an internal battery. But the item I bought didn't have one. Instead it came with a 6 cell external battery which protrudes in the back. Is there any way I can have internal battery added now? I see that some sites like Amazon are selling replacement internal batteries; can I buy it and install in my laptop? Thanks in advance for your replies!

I have what appears to be a msata and a m.2 slot. The msata has a Intel dual band wireless card in it. The slot to the left looks like a m.2 slot with nothing in it.  Will any 2242 ssd fit in it or does it have to be single sided. Also the laptop has no internal battery just a spacer. Is it possible to add a battery to this model? There is no 3rd m.2 slot under the internal battery spacer, can this be added to the t440? Laptop is the standard t440 (not the s or p)

Having sent the G20 back under warranty for a complete overhaul I got it back and put it away. It was not used for 2 years after checking everything was working ok. Now when I switch it on I get a dos like screen and I am told the internal battery has gone!

I did not even know it had one which apparently runs out after about 5 years. Is this true and if so why does no one tell you about this. It is also apparently only accessible if you strip most of the computer down - is this correct and why is this so inaccessible?

Do they assume these machines are not going to last 5 years?
What are my options, is this worth the time and money to get the battery replaced or should I just sell the computer as its set to factory settings as new.
Opinions would be appreciated.

Answer:Qosmio G20 -156 Internal Battery issue

Hi

I think you mean the BIOS battery (also called CMOS battery).
Its mounted (in many cases also soldered) on the motherboard and this battery provides power for BIOS.

Usually this battery would be charged always when the AC adaptor is connected and the notebook is powered ON.

As far as I know the battery should be charged for about 18 hours in order to get it fully charged. So connect the AC adaptor and leave the notebook running for a longer period of time (18h). then check if this battery would be charged.
If not, then the service technician should check this and if necessary this part should be replaced.

Hi there,  I've been trying to find the solution on my own but I'm just out of my depth here.  When I turn on my laptop I get a black screen that tells me there is a 601 error with my internal battery. I'd like to purchase another battery and replace it because I need my laptop working perfectly for the bar exam in July 2016. Is this something I can do myself or should I take it to a shop? I think this is the battery I need: 6 cell 62WHr 2.8 Ah lithium-ion battery Can someone confirm that? Also, I'm not sure what the internal batter is. There's a battery that I can eject from the bottom of my laptop. The Regulatory Model Number is HSTNN-LB3N and it's a rechargeable Li-ion battery. It also says to change with HP spare 671731-01. Is this a different battery than the 6 cell one I mention above?  I'd greatly appreciate the help! Thank you in advance!

Hi community,let me first explain how I assume the switch between headphones and speakers should work:I turn on music or anything esle and if no headphones are plugged in, every sound comes from the internal speakers. Now if I plug in headphones then the sound comes exclusively from the headphones. If I pull then out again the sound comes from the speakers and so on. In my case the situation is the following:If I have no headphones plugged in and turn on music, then I hear if via speakers. If I decide to continue listening to that music via headphones and plug them in, then the music continues to come from the speakers, but for example the notification sound from outlook comes from the headphones. This works vice versa.If I open, say youtube to watch a video, while having the headphones plugged in, I will hear the sound via them. If I now unplugg them, the speakers will stay silent.What can I do that if there are no external speakers plugged in (headphones etc.) every sound will be played by the internal speakers, if I plug in some sort of external speaker it comes from them and if I unplugg it it switches back to the internal speakers?Thank you very much for your help!Best regards

Hi, recently i bought from ebay an thinkpad t440 20B7-S0FV11 i5 4300u with 8Gb of RAM and 500Gb hdd.This laptop came without front battery (internal), it just came with the external one so i bought one internal battery on the internet and put it myself on my laptop.I press the reset button on the button of the laptop and turn it on.The issue is that windows (and also ubuntu) didn't recognize the battery. Windows say: "battery not detected"!I already update BIOS and everything and the battery still not detected.Initially, i thought that the battery was damaged but i charged it directly from the external battery, plug it inside of my laptop and turn it on. The laptop still not recognized the battery (and did not charge it neither), and windows says: Battery not detected!But the laptop work without external battery and charger, just with internal battery! (despite that not charging or detected) So i thought that the lithium cells are probably ok.I want to know if it's a battery problem, some lenovo firmware on battery (since battery came from china) or some problem with laptop!Thank you all.(sorry for my english)

I have a Lenovo Thinkpad T440 and the batteries are showing battery error in the Power Manager. I am unable to update my BIOS to see if that will solve it and my batteries don't seem to be eligible for a Firmware update. My Warranty is also expired. Anyone have any suggestions? error is showing up on both batteries  (Front internal and rear removable). Laptop works fine when plugged in but will not power on if it does not have a charger connected. Batteries don't charge at all (With or without it being powered on) All suggestions welcome. Would prefer not to have to get a new battery set as these ones are relatively new and shouldn't be throwing this error. I do not have a spare Thinkpad I can test the batteries in or that I can test a known good battery from.

Answer:T440 external battery not charging

Hi Valdemar_d,
 
Welcome to Lenovo Community!
 
As per the query we understood that you are facing the issue with External battery not charging on your ThinkPad T440.
 
The problem you are running into is Power Manager conflicting with the 80% BIOS threshold.  So to avoid this, either keeps the Power Manager threshold for both batteries below 80%, or else both batteries above 80%.
 
Hope this helps.
 
Best regards,
Hemanth Kumar

Hi all, recently I bought Lenovo t440. How long should last battery (s) in this laptop in normal or power saving use with screen at 65-80 %? I know this laptop have two batteries , and both of them are 3 cell right ? Extended battery have 6 cell, which I don't have, but might I would  buy it . I noticed my both batteries last max 3,5 hours max 4. This is from I what know - slightly short.  Before I buy some of this batteries I would like to know which one is maybe fault, or worst of them. Maybe is faulty inside battery, maybe plug in one.  My battery indicator in win 8.1 shows both bAtteries ... It seems windows recognize capacity or remaining storage from both of batteries in same time,or, should I say, it seems my laptop is running on power from both of them in real time... Maybe laptop should drain batteries one by one ? Ok, if this is normal, let's skip it     main question is still,how to check each batterie health / or one by one in mY T440  to see which one is maybe faulty or less good, for potential replacement ?   thank you all

Hello The subject of this message says it all. When I want to start my T440 without AC power, it happens quite often that the machine will not start at all - no lights, nothing. In such a case I am forced to plug in AC power just for 1 second, hit the power button and then my T440 will start. Sometimes it starts without AC power, but then again sometimes it does not. it seems random. Note: I am not talking about resuming from hibernation or etc, I am talking about a new, fresh start.I searched the internet in detail for a solution, but no result to my problem. Of course I read from other users having problems starting up their T440, but never exactly the same problem.My battery lasts for a couple of hours.  What to do? I am in Myanmar, far away from support. I tried many things already, including taking batteries out, start, turn off, start again.... Many thanks for your help.

There have been a few posts on Monitor issues - But I think I can shed some light... Hardware:Updated Ultra Dock Severial T440 and T440s (win 8.1)3 External Monitors (VGA, DVI, DisplayPort)1 USB monitor If I leave the unit for a bit, it goes to sleep / screen saver (even tho disabled in windows) - When I wake it, ONLY my USB monitor comes up.  If I don't have the USB monitor on, the issues looks like my machine has hung. Since I have USB I can load the monitor settings (Windows)  - and for each Monitor on the dock, in the pull down beside 'Multiple Displays:' I get 'disabled'.   If I flick each one back to extend, the monitors all come back on.  Now after being in the dock - when I go to power up standalone, the internal monitor turns off,  I need to Hard reset to get it back on (Hold Power button). I will test taking it out of dock and plugging in the USB monitor to see if that makes a difference.  

Answer:T440 Ultra Dock - after being in dock - internal Monitor does not work - USB does - disabled

I pulled my unit out of the dock - powered up and the display goes blank (if you look carefully you can see the bios boot screen, then black, then you can see the backlight turn off. I plugged in the USB monitor and boom - I could log in. Once Logged in I could see that windows still thinks it has some of the monitors from the dock, and the internal display is set to disable. So the issue is the detection / setup of monitors in/out of the dock. I've done about all I can do for dubugging, I hope lenovo can pick up from here. if not I'll have to call lenovo support.

My T440 has an issue where the keyboard, mouse trackpad/trackpoint, and LCD all don't work. However, the mouse, keyboard, and display are all working perfectly with external USB/VGA devices, and the keyboard lights up during the boot. I am able to log in via the fingerprint scanner. This makes me think that maybe the lid sensor is convinced that it's closed. Is this a reasonable hypothesis? What are my options for fixing this?

Hey everyone,  I have a T440 and I have noticed that sometimes when I am two finger scrolling it will cause the screen to jump upwards (I am using reverse-Y axis scrolling; when it is non-reversed it causes it to jump down). It seems to do this at random - no matter if I scroll fast or slowly it will do the jump, maybe 30% of the time. I have installed all hardware updates, and everything else is up to date, so I am not sure what it could be/what else I could do to solve it. Any help would be greatThanks,

I need some help please !, I have a thinkpad T440 (windows 7) , did a ppt presentation and had some issues getting it to work properly on a second display, I think I may have even managed to add in a third monitor, Now the pc is on and has a blank screen, I connect another screen (VGA) and have another blank screen, but I can move the mouse between both, but when I press the start button I can't see anything as I believe this is on the 3rd screen, it works in safe mode ( as one screen) but I can't seem to get it to default the screen settings, have rebooted it a number of times to no avail, any ideas please !!!

Similar to why some people don't like to charge laptop batteries to 100% and in line with preserving battery life, I also rarely let my laptop batteries hit a rock bottom 0%. By default the laptop was set to hibernate if the battery reached 5 or 6% but I raised this lower limit to 10%. (i.e. auto-hibernate at 10%) I heard the reasons why it is bad to let batteries completely drain to 0. Main one being something to do with the battery cells falling into a "deep slumber" and simply not waking up unless you send the laptop in for a "shock treatment". Like the "gate" at the entrance to the battery cells don't even have enough energy themselves to even open the "gate" to allow energy to go into the cell itself. Anyway, is there a way to stop the slice battery from reaching 0%? So that once the slice battery goes down to 10%, for example, the laptop will switch over to use the main internal battery?  













Solved!

Go to Solution.

Answer:laptop allows 39+ slice battery to reach 0% before switching to use internal battery.

There is not currently any way to do what you request.  But draining the battery to 0% isn't really 0% capacity of the battery. The 100% charge of the battery is normally 4.2 volts. The 0% charge state is really 3.0 volts. So when the battery reports 0% it is not really zero volts because the cell must be kept at higher state of charge for the health of the battery. The battery firmware is intelligent enough not to let the battery discharge to a point where the battery health is impacted.

Hi All, 1) T440 usb port is connected to Cisco switch UART port via BAFO usb2serial adpater.2) when Switch is powered on, switch boot messages can be seen in Hyperterminal running on T440.3) Now if i send a text file from T440, switch is not receiving it. (Actually switch waits for some character sequences, to decide whether to boot from UART or NAND. If those characetr sequence are recived then it boots from UART else from NAND. In my case it walways boots from NAND.)4) Tried with another T440 same issue5) Tried with X1 carbon same issue.6) With the same setup tried with T420 model, it WORKS7) Tried with other USB2 serial adpaters but no luck.8) I have installed latest prolific drivers.

I recently received my 39+ slice battery and, after attaching it to the x1, set the charge thresholds for both internal and slice batteries to stop at 90%. (I used this threshold on the internal battery and hoped to set up the slice battery to 90% also.) i.e. start charging when below 86% and stop at 90%. Unfortunately I have been unable to maintain both batteries at 90% charge. After extensive testing, updating drivers, software, firmware, bios, resetting battery meter and various charge threshold combinations, etc., it seems that the slice battery won't charge past 80% unless the internal battery is allowed to charge to 100%. If I set both batteries to charge until full (100%), this happens:1. internal battery charges to 80%, then stops.2. laptop switches to slice battery. charges slice battery to 80%, then stops.3. laptop switches back to internal battery and continues charging it to the 100% threshold.4. finally laptop switches back to slice battery and finishes charging it to 100% also. However, if I set both batteries charge threshold to stop at 90%, this happens:1. internal battery charges to 80%, stops.2. slice battery charges to 80%, stops.3. internal battery starts charging again until it reaches the 90% that i set, stops again.4. and then, that's it....lol.. The slice battery does not continue to charge until 90%. it just gets stuck at 80%.

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? Thanks a lot for your help. Greets from Germany enweh

I have four computers that are connected at any given time to the home network. I believe have two issues here.

The first, all of the computers connect and surf the Internet at very slow speeds. Sometimes it seems like I'm back on Dial-up. My MacBook (which is my main computer I work from) connects to the Internet with an Ethernet cable directly into the DSL box. Even if I turn the other three computers off in the office I still run slow on the Internet. Any thoughts on how to improve this? My DSL provider says its an issue with our setup. Great thanks for the help!

Second, my Mac overall seems to be running very slow. I have over 14GB of available space so I would not think that the computer is in overload.

Any support would be greatly appreciated.
 

Answer:Moving at turtle speed - Internal Network issue or DSL issue?

If you have more than one computer, and all exhibit the same symptoms, it's hard to believe they're all bad.
Pick one that doesn't exhibit any other issues and do this:

Register at DSLReports and run their Line Quality Tests. It's best to run this test with a direct wired connection to eliminate any wireless issues from the results. It's useful many times to run this test several times, and we'd like to see each of the results. Post the results link from the top of the test display page for each test run here.

The link to post is near the top of the page and looks like:

If you wish to post this result to a forum, please copy/paste this URL
http://www.dslreports.com/linequality/nil/2357195 <- sample only, yours will obviously be different!
and your IP will be disguised.

Copy/paste that link here.

Note: You will have to enable PING (ICMP) request response either in your router (if you have one), or in your computer's firewall for direct modem connections. This is very important to get the most important part of the test to run.

Hi Nicktr,
 
Welcome to Lenovo Community!
 
I think the problem you are running into is Power Manager conflicting with the 80% BIOS threshold. So to avoid this, either keeps the Power Manager threshold for both batteries below 80%, or else both batteries above 80%.
 
Hope this helps.

Hi, Just to clarify, the 601 error relates to your notebooks main battery ( not the rtc cell on the system board ). If you're happy with running the machine on mains power full time, there's no issue with that and you can simply remove the battery. If you do want to replace the battery at some time, you can order a new one through HP Parts Store or ( and often less expensive ), just google the full Model No. of your dv7 series notebook including the term battery. Regards, DP-K

It will be somewhere on the motherboard. It's a flat round battery like those in a watch only larger. On some older PCs, the battery is soldered to the motherboard so you may need to take it to a shop to have it replaced if that's the case.

Answer:internal battery error 601

It would help to know your laptop model. But I would say the "internal" is the CMOS or Real Time Clock battery. That is why I ask your model because it is unusual to see one of those die in less than 5 years. The model of the laptop would also allow us to show you how to replace the internal battery. It can be quite a job although the little battery (like a hearing aid battery) is very inexpensive usually.

I found one internal battery in www.treotiger.com.Is any one has any experience with internal battery?
I am looking forward to the reply..

Hi. After just 13 month, the battery of my Thinkpad X1 only lasted 15 minutes, and I got a warning that the battery was in a bad shape . I used the Thinkvantage Power Manager to recalibrate the battery (German Version: Rekalibrierung durchführen) , now it shows a remaining time of 48  hours. I try to recalibrate the battery again, but the recalibration process stops after a few (10 to 30) seconds. Anything I can do to get reliable remaining battery operation time? Thanks...

Hi Remy_Gruetter:
 
This is an interesting problem, let me start out by asking, have you downloaded the latest battery firmware?
 
If not, or if you're unsure, check here: Lenovo Battery Firmware Update Utility
 
This is at least a good place to start.

I am a IT tech at my company, we are a Lenovo shop. We recently purchased several x240's and when I get them I have to add memory to them. I noticed when I opened this last one up it had an additional battery inside. After I put it back together I tried to power it by that battery but it wouldnt start. However I plugged in the traditional battery and it started. Can you tell me the reason for the additional battery and how that works? Also as a side note, there is an issue with the internal cache card. I found that upon trying to image the laptop with our company image, it will not see the current hard drive if the cache card is added to the laptop as an option. It will only see the 14.9gb cache card as the main hard drive. The cache card has to be disabled and is on the side of the motherboard that you cannot see by removing the bottom for the image to install properly, which by the way will void your warranty if you do it yourself. Also the cache card is not HIPAA complient which is something we have to observe at my company.

Answer:X240 Internal Battery

Internal built-in battery starts when external one is disabled or absent as well as the AC adapter.One of the reason built-in battery allows replacement the external battery when that's fully discharged or for the management purpose while laptop is working w/o AC adapter.Also the laptop has a less weight with built-in battery only.Note you have to disable built-in battery before you perform any servicing laptop built-in parts - RAM sticks, disk drives, wlan/wwan adapters etc... Do it in the BIOS Setup menu. For more details read laptop User Guide.

I have my laptop for approximately two years and now I am getting a message about the Primary (internal) battery 601 needs to be replaced since it is detecting the storge capacity to be low.  I believe this is the inside battery but how do I determine if the battery is dead?  What prodecure do I use to correct this matter?  I am going to college online.  Would this cause a problem fo rthe storage?  I have to download my books for the virtual classroom.  Any advice would be helpful!

I can't find info specific to your notebook if I don't know what iti is.look at the barcoded sticker on the bottom of the notebook and post everything that is there except the serial number.You need to check the battery status and also to calibrate the battery. All I can supply is generic information from a randomly chosen notebook series. Best regards,erico

I've upgraded my T440 to Windows 10 and the latest mousepad driver seems to be giving me issues. With the Synaptics driver 19.0.17.27 installed, trying to select a new window to make it top most will often fails. That window will hide behind other windows. If I try to uninstall the Synaptics driver once, the window z-order issue will be fixed, but the driver is like half uninstalled and most mousepad function will no longer work (2 finger stroll, right click, button press)  The input cursor will also jump around too while I tried to type. Is Lenovo aware of this issue? I think I've seen another person in another forum mention this.  This is becoming quite frustrating for me.
