I didn't worked on this model yet. but you standard voltage check. test voltage on power button, alw voltages (3.3V and 5V), also see dc contector voltages (maybe its solder joints are cracked)

Hi. Now I get te laptop owner and he tell me how is laptop go to hell.

He forget turn off and pull out 220V pover cable from eletrical network, between storm.

I thin it is not worth the repair, mboard maybe is complete dead.

Thank you again.
