Q: The latest, as of 2/12/17 about the T460s battery and battery life

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 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.

A:New T460s: battery at 87% maximum life already

Where are you getting these readings for the Design Capacity? The battery capacities are:
 
Main: 23.54 Wh
Secondary: 26.33 Wh
 
Those numbers do not change. Have you tried to do a Battery guage reset?

A:Improving battery life on T460s

My battery drops from 100% to 93% within 20 minutes. Is this normal? I am using the lenovo optimised power plan. Screen brightness is at 40% and doing nothing else other than surfing on google chrome.  My configuration is a i7-6600u, FHD IPS non-touch, 512gb PCIe ssd and 8gb ram.

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

Can anyone shed some light on hardware encyption w/ the P961 and or provide any additional information that may help me make a more informed decision? I also noticed the PN on Lenovo's store (4XB0N10301).

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

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!

Ever since upgrading the BIOS in my system to the latest 2.3.1, the battery life in my system has gone all to ***. I used to routinely get 8 to 10 hours use out of it, and now, if I'm lucky, I get two hours. Tech support has already done an on-site battery and system board replacement, to no avail. I can sit and watch the battery percentage drop in the ePSA screen. System demand supposedly around 2,000 mA, which should yield 30 hours of runtime with the 60 Wh (brand new) battery, but yet goes down to zero in just over two hours. System is also running hot, I notice. All this in the pre-boot diagnostics, so no OS load on the processor.
Anyone else seeing this issue? Last time I updated the BIOS before this was back in April, 2017, which really improved the battery performance.
Any suggestions?

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.

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.

Hi there!  Since the battery life of 320S is less than stellar, I tried to find ways of enhancing it beyond the beaten paths. When examining which batteries are compatible to mine, I noticed that besides three two-cell types (7.2V),- 5B10M49825- 5B10M49823- 5B10M49822 (this is the one the laptop came with)three three-cell units (11.4V ) were offered as possible replacements. These are:- 5B10M49826- 5B10M49824- 5B10M49821 My question is:What effect does the change of the battery voltage has on the battery life? Has anybody tried this change and what were the results?I think this strongly depends on how the onboard voltage is generated: A very primitive voltage regulator would simply turn the excess voltage into heat and would have no effect on the battery life.A more sophisticated regulator would detect the incoming voltage and could (the conservation of power applies) turn additional voltage (e.g. 11.4V) into additional current at a lower voltage (e.g. 7.4V), yielding a longer battery life. Can Lenovo say how the onboard voltage regulators will react to an aleviated input voltage ? can the battery life be extended this way?Has anybody already tried this conversion and if so, what was the result? Best regards and thanks in advance,Matthias

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?

Hello!  I am seeking the sage wisdom of veteran thinkpad owners for an upcoming purchase.  I am considering an x250 (i5, 256 ssd, 8gb, 1080P ips non touch, with nothing but a fresh install of Windows 10 pro 64 bit and MS office pro plus) to use for the next two years while I complete a degree(mostly paper writing, web browsing, netflix/youtube etc..nothing heavy). I prioritize a good keyboard, good battery life, light weight(under 3lbs), durability, and saving money if possible.  With that said, I can't deal with laggy performance and lackluster battery life. I "could" buy a new laptop, but am having a hard time justifying spending that much since my usage is so light.  My previous laptop was a macbook air and it served me well, but the keyboard never really impressed me. I sold it, bought a nice Chromebook(12.5 inch screen) and pocketed the change. I have not had a "real" computer for a few years now and it's time.  What say you? 1) Will the above spec x250 provide me with decent performance/battery life for the next two years?1a) What kind of battery life can I expect with this setup and a flush battery?  2) Any other recomendations? I really like the X1 carbon, but the price is tough to swallow with all the issues I am seeing.

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....

A: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.

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.

My Yoga 3 pro is still a nightmare and so far is unusable given onging battery problems. However I digress. The thing wouldn't charge past 72% and took 2 days to get to that from 51%. So yet again I searched the net hoping to find something new and I noted yet another updated battery guage realeased only a few days ago. I also noted that someone had suggested deleting the windows battery drivers in Device Manager after disconnecting the battery which I figured couldn't hurt so went ahead. Once I reconnected the battery, plugged it in and waited for it to download the battery drivers, I noted it didn't install the ACPI component. Now lo and behold, I have no battery guage at all. In fact it says "The battery is not used", but of course it is. I then tried the latest battery guage driver but no improvement. Can anyone help in this age old problem? Cheers

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!!!

A: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.

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.

A:How to determine the correct battery for my T460S

All batteries in your list are compatible with T460s, they differ by manufacturer and capacity (a bit)

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.

A:T460s - Replacement Battery Questions - Out of stock

I would believe them on compatibility, but expected ship dates are always less reliable.  I always think that I only believe ship dates after parts actually ship.  My doubling ship dates is for all vendors, not just this one.

In my T460s there are 2 internal batteries.When working on 2 full batteries I get sudden death - just like unpluging battery - every time when forst one is 0% and it swiches over to other battery.After turning device on again it works normally from second battery. Looks like the swiching is faulty. What can I do about this? Can it be solved throug software settings or it is physical issue.

So I got my T460s a week ago. It was preloaded with Windows 7, where one could set the battery into conservation mode.This left the battery at a 50-60% charge when the computer is plugged in for long periods of time.In Windows 10 I can't find this option. 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?

Does anybody know if it's a good idea to replace the rear 26Wh battery (01AV406) with the 24Wh front battery (00HW022)?! I need to change the rear battery of my T460s after almost 2 years and Lenovo is out-of-stock for the rear batteries or possible replacements. However, the website does show 00HW022 as available.

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. Otherwise we as a company are basically forced to switch back to Dell :-/ Best regards Christoph Grimmer-Dietrich

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.

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!

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.

This laptop is advertised to have 9.8 hours of battery life. So far, I've only had a max of 1.5 to 2 hours of battery life. No intensive usage, just emails and typing papers. What can I do about this?

I just bought this notebook 17 and the battery completely discharges with little or no use in less than 24 hours. Is this normal, and if it is that seems unexceptable. I have tried to contact support but this seems like the only way to talk to anyone.

A: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.

Are there any tried and true tips for exending battery life?  It seems the battery drops another 20% overnight if I put the 920 in sleep mode.  It does a little better if I shut it down, but who wants to do that?  Are there apps that others have found to be part of the problem?
