Power adapter for Z40-70 worked fine; now not adapted to notebook & will only charge if turned off

2016-12-30, 3:47 AM

Z40-70 bought in 2014. Bought replacement adapter in Aug. 2016. Worked fine for four months. For last 3 weeks, on start up, home screen displays pop-up:  "The power adapter is not adapted to the computer and cannot supply power," showing me a hotlink to Buy a new one.

The adapter does charge the battery when the computer is turned off, but will not work while the computer is turned on.

The adapter appears identical to the original. There is one variation in the model number:

Original model #: ADLX65NCC3A

     Repl. model #: ADLX65NDC3A

Try uninstalling/reinstalling the Lenovo Energy/Power Management software and drivers, and see if that resolves the error.

 

Good Luck,.
