I've seen in another forum post that the battery is replaceable... Is there any manual that explains how to replace it and which battery models are allowed? Thank you very much.

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.)

Hi, You can see any information regarding your batteries by doing the following: type: "CMD" in "type here to search" bar in windows 10Then right click on it and run as administratorThen copy and paste the following line:powercfg /batteryreport /output c:\Energy_Report.html This will generate a Battery report in your c:\ folder, something like this: You will get the model, and serial number of your batteries and also the design capacity and the full charge capacity, this way you will be able to see how much life is remining in your battery. And regarding the way to replace the battery, all you need is to remove some screws to have access to your battery. you can find some good tutorials in youtube. Any comment or doubt please let me know Regards!

I have a T460s with 2 batteries per the attached status.  Battery 2 is discharged first, then battery 1. Issue: When battery 2 depletes, instead of switching over to battery 1, the laptop powers off without warning.  Just... POOF.  I have updated BIOS and am running Windows 10 Pro. BIOS is at N1CET58W 1.26 I have Lenovo Vantage loaded, but when I run it to check for updates, none of the 'System Update' buttons results in any action being taken.   I have done some searching but have not found any information on why the switchover from Battery 2 to Battery 1 would cause an instant power off.

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

I'm looking at buying a T460s or T460p. I looked at the T460s hardware manual, and it seems like the batteries are not user-replaceable. Is this correct? If the battery life is not long enough for my requirements, I would want to carry around spare batteries. If the battery is not replaceble on the road, how about when the battery reaches end of life (after 2-3 years). Is it possible to replace simply by ordering a new one from the website? Also, can anyone from Lenovo tell me why the T460p and T460 are not available on the Japanese Lenovo website? Since Lenovo USA does not ship outside of USA and I am located in Japan, it seems that I am stuck with ordering from whatever selection is available in Japan, and they do not have either the T460 to T460p on their website.

Hello, so I'm in Egypt and my T460s is still in warranty. I sent it to the support center here in Alexandria, Arab Computers so that I could order a replacement battery for my 01AV406 internal battery. After a week they replied telling me that the battery is not available. Currently I'm not sure what to do, I can't order the battery online from the Egypt Lenovo website. What am I supposed to do to get a replacement battery for my T460s?

Thank you to everyone who commented on battery life. After testing several T460s systems, we isolated a fingerprint reader driver that was excessively draining battery life. The version of this driver is 5.0.62.30. The latest driver ? 5.0.88.04 ? will address this issue and improve battery life.
 
To update your drivers, you can follow the steps below:
 
For Windows 10:
Hit Start
Select All Apps
Select Lenovo Companion
Click in the upper-left hand corner and select ?System Update?
 
You can also find the new driver at the link below.

I have had my T460s for about a month now. The battery life has been bad, but that's not my issue here. The issue is that one of my batteries is now at 87% maximum capacity: Battery 0: design capacity 1813 mAh, last full capacity 1787 mAh = 98%Battery 1: design capacity 2032 mAh, last full capacity 1786 mAh = 87% Is this enough to complain to customer service? It actually even went down from 88% since one day ago.

Hello,I have a user here who has a T460s laptop who's batteries are no longer holding a sufficient charge. Pretty sure the laptop has 2 (internal) batteries. When the use takes the laptop out of the office, it's losing power afterabout an hour, maybe an hour and a half. After an hour, I was able to open a chat session with a tech, who said if we clicked on the battery icon down in the sys.tray, there'd be an indicator if the battery/batteries were bad. However, we did that and there is no such indicator oralert. Clicking on the same batttery icon and then clicking on Battery Settings, there are no notifications posted in the windowthat opens giving any indication of any issues with the batteries. Despite that, the batteries no longer retain the charge they once did. Is there any onboard diagnostic that can be run to determine which, or both batteries are bad?  Or any other locationwhere there might be helpI need to weigh the cost of replacing the batteries vs. having the user get a new laptop. Thanks very much! Jim

I have a very annoying problem with my T460s running Ubuntu 17.10 (and 17.04 before that). The system has two batteries and most of the time one of them is fully drained before the other one is used.For some reason the power manager does not comprehend this and as a result the system performes an emergency shutdown the second one battery hits 0... While the other one was at 88% charge. Since the Ubuntu community seems unable or unwilling to fix this I'm hoping that Lenovo or its community can provide some help.

I do have Lenovo Settings installed, but under battery there is no option to enable conservation mode. So how can I enable battery conservation mode?

Hi all, Quick question on battery replacements.. I have a T460s whose second battery recently showed it was having issues (on 46% of max charge available). I thought replacing the battery would be trivial but this is proving an exercise in futility. For reference the laptop type is: 20F9The battery in question is FRU: 01AV406 When I check this battery against the replacements site (https://support.lenovo.com/us/en/partslookup), it indicates that the battery is out of stock. It also indicates that there are a few replacement options, 01AV407, 01AV408, 01AV405. All of which are also not in stock. After chatting with support on this issue, I was advised to call the parts department a partner - Encompass. Unfortunately, their department closes at 3pm PST which is pretty annoying. However when I search for the part (01AV406) on their website (https://lenovo.encompass.com), I'm left with an additional alternative 01AV462 (also out of stock but at least in stock 1/29). My question is, which of these sites to believe or are these all compatible? I find this a little absurd that this information is so unclear and annoying that Lenovo can't keep anything in stock.Double all that since I want to replace my primary battery as well (which will be back in stock on 3/10/19). Insert eye roll here. Any advice anyone can shed here would be apprciated or any other tips for getting these batteries replaced.

Hi Community, I need some advice. I currently have an aging T460s w/ a 1TB SATA SSD in it. I'd like to upgrade to NVMe. My number one concern is battery life. I need to squeeze as much battery life as I can from the system since I'm a very mobile / remote worker. My understanding is that OEM SSDs provide worse performance but better battery on these laptops. AFAIK, the stock OEM that shipped w/ the T460s was the Samsung PM961 which according to the latest benchmarks I can find should also provide the best battery life. I recently found a great deal on a SM961 1TB. Does anyone know if this was OEM shipped with any Lenovos? I'd like to be able to update the drivers on it. Additionally, the ADATA XPG SX8200 Pro looks to be decent with power consumption as well. Does anyone know if it might be better (from a battery life perspective, not performance) than the SM961?  Thanks in advance!-Ryan

After upgrading the BIOS, I am having an issue with my battery. I finally got around to troubleshooting an outstanding issue with my RAM (It was maxing out at 10 of my 20gb of RAM), I found that updating my BIOS resolved the issue. I purchased the laptop in May 2016, and this was the first time I had updated my BIOS. I used Lenovo Solution Center / Vantage to run the updates. I updated my BIOS to N1CET68W (6/20/18). While troubleshooting I ran battery report, and I don't think it is a coincidence that the date I updated the BIOS on is also the date at which one of my batteries stopped working - Attached with a line drawn for when I updated the BIOS. My battery now caps out at 62%. Battery 1: 68% and charging. Battery 2: 0%. Battery 2 will not charge any more. Battery 1: 00HW022, Sanyo. Design Capacity: 23510 mWh, full charge capacity: 17840mWh (Acceptable degradation for 2 year old battery)Battery 2: 01AV406, SMP. Design Capacity: 26060 mWh, full charge capacity: 1770mWh (Significant drop-off once BIOS updated). I have already performed laptop surgery and made sure both batteries are connected. Unplugged both of them, and hard reset my laptop (holding power button for ~2 minutes with batteries out). I tried uninstalling and reinstalling the drivers, and then updating them. Windows 10 x64.

I have been having issues with my battery on my T480 lately. I will have the laptop running around 50% battery and sometimes try to restart it but when I do, the laptop will not power back up. The Lenovo bios screen will post but when the Windows 10 circle starts spinning the computer fully shuts itself off and loses power and I cannot turn it back on until I plug the charger in, but when Windows loads it says I have battery. Yesterday I was using the laptop and when it went from 50 to 49% battery the laptop fully died and shut off and would not power on again until I plugged in the charger, yet showed 49% battery when Windows loaded again. I have been working out in the cold with my laptop and I am not sure if that is or has affected it some how but I can't keep having these types of issues when I need to be able to use my computer in the field. I know Lenovo used to have a tool to reset and deplete and recharge the battery, does this still exist? I ran the diagnostic tool but it finished instantly saying both batteries were fine with a time on the diagnostic of 0 seconds. Not sure if there is another tool I can be using to try and get this working properly again.

A few days ago my PC started making really annoying grinding noises. I restarted my computer and it said that I had a CMOS checksum error, and my computer fans started going really fast and then slowing back down to their normal speed.
The red computer light on the front is barely blinking at all.. I guess I need a new CMOS battery.

But my question is.. the processing/grinding noise I'm hearing, does that have to do with the CMOS battery dying? It started at the same time as when I started getting these errors, but I haven't found any information on irregular noises that correlate with a battery dying.

I don't get what could be making the noise, because it's a processing kind of noise.. not really a fan? I'm pretty sure it's not the hard drive..

Also, will it damage my computer at all if I can't get the battery replaced right away? I'm obviously running it with a dying battery right now.

You`re quite right, the cmos battery is not rechargable.

I've been using a t460s for a few years and like it a lot - except for the terrible battery life. In my normal usage, I get 2, maybre 2.5 hours of battery life, and from other this on this forum and elsewhere online my battery life experience on the t460s isn't unusual. So, can anyone who's been using a t480s comment on the real-world battery life? I am a bit of a power user, and my machines are maxed out in specs (20GB RAM, 1TB NVME, i7, etc.) If the battery life of the t480s is substantially better than the t460s I might be tempted to upgrade, otherwise I'll just keep lugging around my external battry packs and being 'that guy' at cafes without plugs. From the specs the battery capacities are similar, so I'm not really hopeful there's a big difference.  Thanks in advance!

In my 2/12 post about maximizing T460s battery life, I mentioned ordering a basic T460s with 4 GB memory, 128 GB SSD since it?s less expensive for me to upgrade memory and SSD.    The objective is to have the upgraded SSD and Memory, and the settings, formula for extending battery life all together so that the moment the new T460s arrives everything can be put into it. That is the reason for posting about the latest and greatest for maximizing T460s battery life. For upgrading the SSD, my research has led to the Samsung 850 EVO 500GB.  Will a T460s take it.  Can it just be put in or does anything else need to be done regarding bios or drivers. For memory, it?s adding 8 GB.   But it?s not clear from my research what is the best, preferred memory, and what can a T460s take.  What?s recommended or do you suggest? Thanks for any SSD, memory or battery life ideas or suggestions for the T460s. Randy

Hi, I bought my T460s about four years ago and havenever had any issues until now. Recently (within the past month), I have experienced 2 problems with the battery. First, the drainage on battery suddenly became about 1% per minute, when it used to take hours of high memory usage to drain most of a full battery. Second, below 40% charge, the laptop is liable to suddenly turn off without warning. I haven't changed how I used the computer, and the change in battery life happened basically overnight. At this point I get about an hour's use out of my battery not really doing much with my computer before it gets into hard-shutoff territory under 40%. The built-in Windows 10 battery monitoring metrics don't tell me much since it only looks at apps by % usage, and I really doubt Chrome suddenly became capable of draining 60% of a battery in an hour compared to how much battery life I used to get with Chrome open. What steps can I take to resolve this problem, or even just further identify the cause? Thanks.

The Dell Dimension 3000 is a very old desktop, so its CMOS battery very likely needs to be replaced.

If you open the case and look at it, it likely is a nickel-size CR2032 battery, but it could be a different model.

Remove the battery and replace it with a new one.

Im having issues with sleeping and have tried everything from preventing devices from waking the computer in DEVMGR and Power Plan Settings...to checking settings in BIOS (S1+S3 supported) - it turns off monitor, when i press key it comes back on at lock screen - so its trying but something is preventing it..

I had an issue last night and today with monitor turning off / Graphics failing and I noticed before the clock/date was 2002 with incorrect time... I then recalled this PC (used to be my dads) used to have problems with CMOS battery draining quite quickly, the PC was bought in 2006 and is on its 2nd or 3rd CMOS battery.. think it may be its 2nd, seem to be draining too quickly for my liking, I know my dad has kept this PC off & unplugged over night every night, maybe this is why.. he has donated it too me and Im using it and would like to use standby

any ideas?
thanks

Hi,I am noticing some crazy behavior on my T440P laptop battery.I used my laptop directly plugging in for 90% of the times and hardly used my laptop much.My battery used to work fine, but now, it is tuning off and the "Full Charged Capacity" is just dropping every reboot.I really do not know what is going on? Please see some logging details below.As you can see in the attached image, the battery goes from 31.7% to 100% and then while discharging it goes from 81.8% to 5.8%. Can someone please tell me whether this could be 1 faulty cell in the battery? Is there a way I can check?Could someone else have gone wrong? I even let the laptop die (below critical) to see whether Windows is reporting correct charge values, and the laptop actually died a few minutes after going to 0%.P.S: I was running a system load program to drain the battery and simulate the behavior.I even tried a battery guage reset twice, the "Full Charged Capacity" is just dropping since a couple of days now!!

I've had this computer for 2 yrs since I built it. Has a Asus M2N-SLI mobo with athlon 6400 x2. 4gigs ram, Nvidia 9800 gtx, 600W PS. Most of the time runs fine, no signs of problem. Clock's acurate no lost time. Every 2 months or so, in the morning go to boot up and no beep or post. Just runs all fans and everything but never posts.

After first time I figured out when I replaced cmos battery it works fine. But keeps happening every 2 months or so. Any ideas? Battery should last much longer than 2 months. I'm stumped on this one and even my professors at college don't know. One tech support guy said might be a grounding problem with mobo and case. But that sounds weird. Mobo is mounted like case manufacturer says with brass pins holding it up. Please help...
 

A:CMOS battery keeps dying every few months... computer starts but no beep to post

Just got a new cmos battery and it booted up. When I booted up it was resuming windows from hibernation.. Would that cause battery to die? Doesn't sound right to me... Please help. Can't keep buying these batteries.

I'm trying to work out if my Dell desktop computer (a strong XPS 8700) is dying or not, or if it is just one component that needs replacement (my preference).  The computer is high-performance but 3 1/2 years old.  It has not always been turning on the first time when I press the power button and this problem seems to be getting progressively worse.  Today, it would not load some web pages (it loaded some but not others), and one program stalled and would not stop even with End Task.  I already ran the full start-up diagnostics and apparently everything was fine.  I also did a full scan with Kaspersky Total Security (the strongest version) and apparently everything was fine there as well.  Please help!  Thanks!

Hello, Laptop: Lenovo ThinkPad T470 UltrabookType: 20HD I usually do not have my laptop's battery installed when it is plugged with the AC adapter as I use it mainly at home. But today, while I was out, I inserted it (while the laptop was off) and I received the following error message: "Battery 2: A battery error has occurred. The battery cannot be charged. Replace the battery." I've had this laptop for only a year, and everything is up to date. I only take out and put in the battery when the laptop is turned off. According to the battery percentage, it's stuck at 49% and says it's not charging. 49% Not ChargingBattery 1: 100% and fully chargedBattery 2: 0% and not charging I tried checking the battery in Lenovo Vantage, but it just keeps showing the loading animation, but with no info. Does this really mean the battery needs to be replaced (already)? Could it be a software issue? Thanks.

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!

A:sony vaio won't charge battery or run on battery power (CMOS BATTERY FIX!)

Hi askfault,
Do you have any information on how this fixes the battery problem? would be interested to know.

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.

A: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.

Hello everyone! Not sure if this is an issue but it's surely annoying to know, that battery N1 drains at 5% and the other stays at 100%. Is it possible for a mixed discharge between both batteries ?After all the LIFE of the first battery (while using battery only power) is shortened a lot! Is there any option in LENOVO VANTIGE that I am no aware of ?I looked everywhere and i can't find anything.. Bios latest update 1.30 Thank you very much!

A:T470s BATTERY 1 drains to 5%, BATTERY 2 stays at 100% (BATTERY PRIORITY)

Sorry  but see below post.  Basically you cant set discharge order.  The laptop checks battery wear and bases discharge order on that.  Many people including myself have asked for a BIOS switch or at least an option on discharge order but nothing has happened so far and I dont think its going to happen either.  I do not speak for Lenovo..

Hi guys. I have a T470 and after the latest Windows update I encountered a battery naming issue. Before the update batteries had proper order and were named accordingly: battery 1, battery 2, no surprises here. But after the update I noticed the order has changed to battery 0, battery 1 (attached pic below) Yeah yeah, I understand arrays start at zero but what is that? I was just wondering is it just me or you guys have the same situation going on with your batteries? Is there a way to change the order back to "normal"? .
