Question Shutdown won't turn back on

[Jack_273]

I was using my laptop normally nothing intensive and suddenly it shutdown completely.

the laptop was fully charged and charging, it just shutdown not even the battery led is on anymore.
I tried the hold power button for 30 seconds and nothing plugged it back waited and alll yet nothing. I opened the laptop removed the battery and put charger in nothing no led light either. I reset cmos réseated ram tried with one stick and nothing. I'm at a loss of things to do....

The things I recall doing:
One week ago I changed the laptop screen to a new one worked no problem.
And a month ago I repaste the laptop but worked fine then.

If anyone has any idea what I can do please let me know I'm desperate

Maybe anything shortened the board, while you reassembled it.

Did you try it without the charger?

disconnect the display cable and try an external monitor
