Hi. Do you see any backlight on the display ? Any fan spin? Turn on lights or beep sounds ?

If not, start with the adapter. Is the adapter a good adapter ?

Did this laptop work before you received it ? Any liquid damage ?

Do you have a multimeter and soldering iron tools ? To make measurements on the logic board.

No. I connect the laptop to external monitor no changes, fan is ok

I have been using the laptop before it developed the problem.

My reply was deleted, I'd guess something to do with a YouTube link.
I sent you a PM.
