T460s switch from Battery 2 to Battery 1 causes immediate power-off

Q: T460s switch from Battery 2 to Battery 1 causes immediate power-off

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

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!

Hey guys, wanted to ask a question.

Is there a way to have Windows 7 switch to Aero Basic when on battery power. I see that when on the Power Saver mode, it turns off transparency when on battery power. I guess this is enough, but if it was to disable Aero, would that give me more battery life, or should I just keep it disabling Transparency?

Sorry if this is in the wrong category, couldn't find a "Power" section.

Thanks for your suggestions / opinions.

A:Switch to Windows Aero Basic when on Battery Power

Is there no way for you to manually configure what you want to turn off and what you want to keep on.

There may be an option for advanced settings?

Im pretty sure that the transparency along with other features is aero...

I have a strange issue. I have a Lenovo T60 laptop and I am experiencing problems with the power management/power guage.

It will often show the battery not installed (power gauge is a greyish-white color with dashed lines) or it shows a red X. It does not matter if I am on AC power or on Battery power, it will show the full range of power, battery level, not installed, or an error.

I have searched Lenovo's site and I seem to remember seeing an FAQ about this, but now that I need it, I cannot find it.

What can I check or do to stop this? While it is annoying, I am not sure if I am having a battery problem or not. I did check my battery on Lenovo's site to see if it was recalled and it is not.

I do appreciate any help that any one can give me.

Thanks!

Dear All,I have Lenovo Thinkpad T460S purchased almost a year ago. Today I suddenly faced problem in charging battery. Charger is plugged in and battery icon is showing "plugged in, charging" but actually it is charging very slowly. Normally battery is charged in one hour or so but today it took more than one hours to reach only 24% or so. Furthermore, soon after plugging in, battery icon shows "filling in process" for few seconds then stopped i.e no filling in process. Furthermore, after whole night charging, battery is now 94% charged, battery 2: 100% charged, fully charged; battery 1: 0% charged, not charging (please attached images).Please guide how to get rid of this problem?Thanking in advance. Shahid

Hoping this problem will be noticed by more people, the original post on this issue came from:https://forums.lenovo.com/t5/Linux-Discussion/T470-Linux-Power-Bridge-wrong-discharge-order/td-p/365...https://www.reddit.com/r/thinkpad/comments/63odjr/t470_battery_order_question_internal_discharges/ Brief description: same problem with OS including Win 10, Ubuntu 16.04, Gentoo etc. The internal battery always gets discharged first regardless its remaining power, which is generally harmless but seems not so good for the internal battery life. With my own T470 machine, updated with the latest 1.29 BIOS, this problem remains. According to searching results online, this little bug came with early versions of X's and T' including T460. PS: this issue had been successfully fixed with T460 via BIOS update 1.26, hoping it would be fixed with T470 sooner or later. Best regards.

Hello everyone,
I have been having a problem with my laptop recently. A few weeks ago my laptop turned off, and wouldn't turn back on. I did some googling, and found suggestions to remove the memory, SSD, and CMOS battery, wait, then put them  back in and try again. When I did that, it didn't work the first few power button presses, but then it turned on. It has been consistent like that. I have the battery out, and on AC only, when I remove AC and CMOS battery, then plug the AC back in, the laptop will boot after hitting the power button a few times.

Any suggestions?

So, I had opened months ago a thread here about the short battery time with the T470P. I got my hands on the biggest available battery (72Wh), but still manage, even after a gauge reset, to get around 5h battery time, only using Firefox, and minimal Words/PDF. All on POWER saving mode. What's going wrong with the T470P that it wont even reach half of its promised 12h battery time? (I know those are Airplane mode numbers, but 5h is a joke compared to those)

Over the last few months I noticed that the battery meter on my Dell Inspiron E1505 laptop was blinking red to green and back... so having had this laptop for several years, I assumed that I would need a new battery soon. The adapter power cord was also beginning to lose some of its covering near the plug in site so I ordered both a new battery and power cord. (That was about 2 weeks ago).

Upon receiving my order, I was very pleased to see that when I installed the new battery and new cord, the battery already had some charge (I didn't note how much). I felt relieved to have my mind at ease that all was now well with my computer. (little did I know that I'd be needing help less than two weeks later!).

Important note... I very rarely use my laptop without the power cord... (past experience proved to be frustrating because I always needed more time than the battery provided.)

I've probably only used the laptop "on battery"... a few dozen times over the last 3 years!

Now... I am in a dilemma!

Yesterday, I took the laptop with me out of town when my husband and I did some real estate hunting.
Instead of using the laptop on battery... we had it plugged into a special power converter for use in the car. I noticed that whenever we stopped and turned off the ignition... the laptop would lose it's power immediately, and as we resumed our travel... I'd have to restart the computer... and there would be the "black & white" warning... Read more

A:Battery - Vista is not able the retrieve the power options for the battery

Hi

To be honest I have no idea what you are talking about.
The Vista power options are a part of the Vista OS and you don?t need to install anything.

But on Toshiba notebook the Vista power option would be extended by some Toshiba power options.
Are you speaking about this Power Saver options?
If yes, then I would recommend reinstalling the VAP (value added package) because these power options are a part of VAP.

This problem occurred with prior Win 7 Home O/S, so I upgraded to Windows 10. Heavens-to-Mergatroid!  This laptop runs just fine when only battery is powering it.  However, once I also plug in the power cord, the O/S does a hard crash within 1 to 3 minutes. How special! I can get about 2.5 to 3 hours when using the battery, but not if I also plug in the power cord.  That means that when the battery gets low I must perform a standard shutdown and then insert the power cord which recharges the battery if I don't turn  on computer.  If I then start the computer with both connected, it crashes.  I am not patient enough to live with a computer that has to be recharged every couple of hours.  HELP! I suspected a heating issue, so I took the back panels off and thoroghly cleaned the fan vents and other cracks and crevices using canned air, but this did not fix the problem.  Since in runs just fine on the battery, I deduce it is NOT a heating issue, neither dust or heat paste issues.  (I also used a cooling mat to no avail) Im 70 years old living in God's waiting room, but parts of my body are 18 to 30.  However, I do have "Essential Tremors" in both hands so I cannot do a full laptop disassembly even if I want to, which I don't.  I cannot afford to pay a computer repair shop $100 or more to try a fix this vexing power issue.  Other than hocking my car (it's too old also) to buy a new laptop, does an...

Hi, my girlfriend in Beijing has an Acer Aspire S3 latop. She bought a new battery for it a while back and told me it was no good. I was in Beijing recently messing around with it and found that actually the battery is fine (lasts for >4 hours) but when unplugged and running on battery power, the laptop often just cuts out suddenly (loss of power). I took the battery out and had a look and cleaned all the connections but they seem fine.

The next part is the strange part and which I hope might give someone a clue as to what's going on...

When it cuts out, it will never restart again unless the mains power cable is plugged back into the laptop. As soon as that's done and the power button is pressed, it starts up again and the cable can be taken out immediately (I mean immediately - you can plug the cable in, push the "power on" button and pull the cable back out in less than a second) and it will start up and run fine on battery again... until the next time it suddenly cuts out without warning.

Because any unsaved data is lost and because the laptop cannot restart without the power adaptor, this very portable and light laptop is now reduced to having to be kept at home all the time and plugged in, which is exactly the opposite of what she bought it for.

Anybody have any idea what the problem could be or suggest some tests that could be done to find out? She took it to a local computer shop but the guys there had no idea.

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.

Three years ago I "upgraded" from a T440s to a T460s and I've been suffering the consequences of the T460's terrible battery life ever since. I'm a mobile worker working mostly in cafes, often outside, so battery life and screen brightness are vital for me. The T440s was brilliant - I got 8-10 hours of battery time up to the end of its lifetime, usually working at full screen brightness. Now, with the T460s, the screen is unexpectedly less bright (why?), making it difficult to work outdoors, and at this point I'm down to maybe 2 or 2.5 hours of battery life (from the original 3-3.5), meaning I have to carry the cord with me, thus negating the weight advantages of the T460s over the T440, plus deal with finding places to plug in at cafes. I've periodically perused this forum for fixes, assuming that an issue this big that obviously affects so many people would be dealt with by Lenovo in time. It seems however that Lenovo is simply writing this one off, and people are slowly upgrading to other models. This is not an option for me so I need to find some way to improve the situation on my current machine. Forum experts, is there perhaps some fix that I've overlooked? Does anyone have any tips? Lenovo, what do you have to say about this? Thanks in advance.

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.

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.

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

Battery 1 : No battery has been detected. Reinstall or recharge the battery to solve the issue.  That's what I'm constantly getting while using the laptop. The message has been appearing since two weeks or so and I don't know what to do. Battery 1 is not detected by the laptop when I insert the battery number 2:  But if I remove battery number 2, battery number 1 works properly.  I tried to hard reset the battery, uninstall the battery drivers and restart the laptop, last but not least update all the updatable, but nothing has solved the issue.

This has recently dropped in price to where it is now quite reasonable. Is this information accurate or am I better off going with a retail model? I'm also a Bitlocker user and would LOVE to utilize the hardware encryption feature which (while some information has been conflicting) requires OPAL which is disabled on some SSDs by Lenovo? 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). Does anyone know if this is the PM961? 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.

Hi, I am facing a problem with a T460s running on Windows 10 1709. Each time this laptop starts on battery power/runs on batterypower/switches between main power & battery power, it will experince a BSOD and/or a scrambled display followed by a total freeze after 1-3hours. In addition, it still goes into Hybernate regardless of the fact that all sleep & hybernate functions have been deactivated. I have run numerous tests to check if this is a hardware problem, and each time I get a clean bill of health for the hardware tests. I tried to run the online Lenovo test for the hardware, but I seem to have a problem installing the Lenovo tool. Can anybody help on this?

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.

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!
