jam97 Posted April 19, 2018 Share Posted April 19, 2018 Hello, Since windows 10 released, I installed many versions of windows 10 in a hope that battery issue is solved. The issue I mean is that windows 10 does not show the correct value for the remaining time for the battery to get fully charged, instead it shows unreasonable time e.g. "01 minutes till fully charged" no matter how much the real remaining time! I read a lot about this bug, most say it's BIOS related issue. Any fix, ideas ? Thank you, Quote Link to comment Share on other sites More sharing options...
Bos Maior Posted April 19, 2018 Share Posted April 19, 2018 Doesn't happen to me. It just says 100% charged (which is correct; this laptop is always plugged into a socket). I use the latest BIOS provided by Lenovo, unmodded. Quote Link to comment Share on other sites More sharing options...

Could you please try to discharge it to e.g 50% then plug it into the AC and check the remaining time to get fully charged? Thanks, Quote Link to comment Share on other sites More sharing options...
Bos Maior Posted April 21, 2018 Share Posted April 21, 2018 OK, so I discharged the battery to 33%. It then took almost two hours for it to go up to 99%. And then it got 'stuck'. That is to say, it never actually got to 100%. There's no longer any indication of how long it'll take for it to 'fully charge', either: the text is '99% [space] until fully charged'. Apparently, then, the OS doesn't quite know at what point to say that the battery is 'full'. 1 Quote Link to comment Share on other sites More sharing options...

Bos Maior Posted April 22, 2018 Share Posted April 22, 2018 Yes, that happened to me too, once it got to 60% or so. When I rebooted Windows marked the battery as fully charged, by the way. A quirk of the OS, it appears. Quote Link to comment Share on other sites More sharing options...
