I am using this laptop from last three years. It was working fine till yesterday before I performed Battery Guage Reset. Now I am facing issue.
When I disconnect AC Adapter and Reconnect it to Laptop. Laptop doesn't shift to AC supply and keep draining battery continuously without shifting to AC Power.
It Only Shift to AC Power by Following Steps.
- Remove Battery from Laptop
- Remove AC Adapter from Socket
- Press Power Button for 30 seconds
- Put AC Adapter in Socket and Laptop and Release Power Button
- Then Computer Will Turn On using AC Adapter
- Insert Battery After that Laptop Charges Battery as Normal Laptop however After disconnection I have to do all this again.
Above way is very incontinent. Every time when I have to remove AC Adapter or there is a power cutoff.
- I am using windows 10 from many months it was okay on windows 10 before.
- My Settings and version of power management has no issues.
- My AC Adapter is fine. It has no issues.
- I am using Latest BIOS available on Lenovo Site
- I tried to update battery firmware however couldn’t find it.
Please suggest me some solution ASAP.

Thanks for using the Lenovo forums.
Try to see if you are able to use an alternate charger for the unit, and see if the issue will persist.
Hope this helps, let us know how you get on.

I followed suggestions from Jansilp, Teslafly, Dave1996 and a few others. Identified the burnt Mosfet, got a new one soldered and now the laptop is functional again. Thanks to you all.
now I am trying to locate where the culprit - 'energy management firmware' is to disable it so the problem will not happen again (or where the battery gauge reset function is).
Thank you to the forum.
