Princetolu94:
My laptop screen goes blank randomly after using it for about bt some hours. Please what's the solution. Image below

You are using it on top of bed always, bed will not allow the heat to blow out, it mayb the fan is not blowing the way it suppose to.
The solution is to consult an engineer to check it for you.

I Believe There Is A Connection At The Back Of The Screen Kinda Like A Wire Thats Shaking, Its What Transfers Video To Your Screen It Really Shouldnt Cost Much, First Time It Happened To My Hp 250 And I Took It To An Engineer He Called It "trigonal" Something Something Problem(but It Shouldnt Cost More Than 1k) but now if my screen goes blank i just apply a little bit of pressure to the back of the screen prolly to adjust the wire and it works perfectly. FYI i'm not a tech guru. and the problem might just be from a non-working fan thereby overheating which sometimes make the screen go blank.

You have been using it for some hours,Still let the bros rest small na.

I see some write up on the screen at the top right corner.

Type and hold CNTRL + ALT + Del , if the box pop up, cancel all running programme, then shut down and boot.
