Guest Posted February 20, 2014 Share Posted February 20, 2014 Does your BIOS still remember the correct time after you pull AC Power and Battery?Maybe it needs a new CMOS battery... Quote Link to comment Share on other sites More sharing options...
wwischerath Posted February 20, 2014 Share Posted February 20, 2014 It sounds like a battery failure. Quote Link to comment Share on other sites More sharing options...
ahhchuonu Posted February 21, 2014 Author Share Posted February 21, 2014 how do i find out if the BIOS as the correct time?so i need a new battery?while i was doing the battery reset, i was playing a game. i didnt read the caution before i reset it and now my battery wont charge. In order to charge my batter, i first have to unplug it from my laptop. Then i have to plug just the ac adapter in. Now, I plug my battery in and it charges. Also, after all that, lets say i unplug the adapter while its charging and plug it back in, it does not recognize the adapter is plugged in. Any thought on how to fix this? This also makes my games have a lower FPS. Quote Link to comment Share on other sites More sharing options...

Robert Posted September 1, 2014 Share Posted September 1, 2014 You are having the same problem many many of us are having with different brands of Lenovo laptop. There are quite a lot of posts about this, including one solution that involves replacing a MOSFAT on your motherboard ...https://forums.lenovo.com/t5/IdeaPad-Y-U-V-Z-and-P-series/Solution-for-laptop-cannot-detect-AC-adapter-after-performing/td-p/1641892Short story is, it's a hardware problem usually brought about by running the battery calibration utility. The only current solution other than DIY replacement of an IC is to have Lenovo replace your motherboard. Quote Link to comment Share on other sites More sharing options...
