Thinkpad Edge e531 will not recognize ac adapter after bios update

2017-08-29, 4:56 AM

I recently upgraded my ThinkPad edge e531 to Windows 10 pro and followed the suggestions to upgrade my bios to help with compatiblity issues. After updating to the latest bios(lenovo driver update)my computer no longer recognizes my AC adapter. Now my battery is almost drained and I don't know what to do to fix this problem.  I  have tried removing the battery and pressing the power button 10 times...no help. I have removed the CMOS battery for 30 minutes...no help. The computer isn't charging at all and my battery is about dead. Can anybody offer some solution to my problem. I have also tried multiple AC adapters. Thanks
