Ideapad u430p adaptive brightness disable issue

2016-10-02, 3:28 AM

I have had an Ideapad u430P for a couple of years and within the last week, all I see is a black screen when I try to start it up.  Nothing happens.   I have held the power button down to turn off and waited a few miniutes to days before turning back on and I still get the black screen.    I have tried the Fnc F2 button and nothing happens 

 

I am not able to access the battery without taking the entire cover off. 

 

Any ideas?

Hi 4GSPs  , 

 

Welcome to the Community Forums.

 

Try connecting it to any external display (press FN + F10 / F10 to toggle display) and check if there would be anything that would show up . 

 

During the process of start up , check on the power LED . Would it stay on solid white (status indicators page 29-30).? Would the caps lock / num lock respond with its led lights ?

 

Those above test is to isolate non display issue from a non post (power self test). 

If it is non responsive , best to have it checked with your local service provider for checking further on the systemboard. 

 

Update us how it goes.

 

Regards
