SOLVED: 820-3332 Black screen with chime and loud fans. No liquid, but very dusty. GPU?


Hi Guys, came across to 820-3332 which turns on and chimes, but no screen neither internal nor external. No Capslock response either.
No liquid damage, but very dusty and must have been overheating for a while.

Not sure if its GPU issue or something else I should look for. CPU/GPU gets very hot, probably the reason for the loud fans.

Also, it does not turn on without a battery. Is it usual for these models?

This board requires 85W charger, to start without battery.
Be aware, strange behaviours reported when used it without battery however.

First resolder U8900 using leaded solder.

If machine chimes, but no USB activity, means it boots and gets stuck soon after; maybe when access GPU.
There is a hardware mod available to disable GPU.
Search the forum, I'm sure is already posted.
