Battery 2 (0%) plugged in not charging in Windows10

2016-02-08, 20:31 PM

I have used my T450s for serveral months, it originally has windows8.1 and I upgraded it to windows 10. Everything went well at first.

 

Then recently "battery 2 notdetected/ installed but not supported" kinda thing keep pop-up.

 

And today when I tried to power on my T450s, this showd before booting into windows:

 

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.
Press the ESC key to continue.

 

Then my 2nd battery is always 0%-5% and not charging

 

My second battery is model 68 which is the right one for my T450s and it is the original one with my Thinkpad.

 

What should I do?

 

(Edited: from "used my T450s  for several years" to "used my T450s  for several months"  :))

Solved! See the solution

Re: Battery 2 (0%) plugged in not charging in Windows10

I'm having an extremely similar situation--in a T440p (which I've used for >a year so far), a day or two ago it simply stopped charging when plugged in (in windows 10 it said "plugged in, not charging"); I tried all the standard fixes but eventually because I had to use the battery, it went down to 0% and is now showing the issues that TenkiGu is describing.

 

Edit:

To provide more information on my situation:

I do not know for sure when I first started having issues, but my computer has logs of the battery charge and it shows it getting fully charged; I believe I then took it out and ran it on battery for a bit, plugged it in again, and the battery never started charging; it just sat at ~80%. Since then I've run the battery down the rest of the way between trying to get it to work and because I needed to use the computer on battery power for a couple of hours. I never did anything particularly odd before it started having issues (eg, I didn't happen to update drivers and then suddenly have it stop working).

The battery itself seemed to be fine (it did last for ~4 hours), but when plugged in it simply didn't charge, even when the computer was shut down fully (which is the really odd part--if it were a driver issue I would've expected it to charge when shut down). I tried doing all the various solutions you find suggested online and in various forums. Now that the battery is fully drained, it simply thinks it is a bad battery (and it still won't charge when fully shut down). I'm starting to worry that even if the battery wasn't bad when the issues started, it may be going bad now.

I had similar (but not identical) issues a while back and fiddling with the energy manger settings in windows worked, but when I had those issues it still charged when fully shut down; now it doesn't.

Ive heard that the cause of our problem may be conflict between Lenovo Power Management and BIOS, but all solution I viewed so far is for windows 8.1 or earlier version. Does your T440p use windows 8.1 or earlier version?

 

BTW: do you know how to attach images? I have screenshots but don't know how to post in this forum.

My computer is dual booted Windows 10/Ubuntu.

 

I'm not familiar with this forum, so other than, say, uploading to imgur and linking to it I don't know how to do images here.

Just to provide some closure on this:

I don't know if this will help TenkiGu, but I was able to try a new (well, borrowed) battery in my laptop, the borrowed battery charged normally. My hypothesis is that the circuitry in my original battery was damaged in some odd way (thinking back, I did slip on some ice and the impact when I hit the ground may have jarred the battery--I didn't think much of it at the time, but that would make some sense) that prevented it from charging (but not from discharging).

At least it is a simple fix, if somewhat irritating to have to do.

Thank you. I think I should at least have a try, so I'll get another external battery.

Finally the problem was solved after I updated the lastest version of drivers.

3 person found this solution to be helpful.

This helped me too
