T60 hardware faults

[Hixon]

Dear Forumers,

I have got this problem that my T60 does not turn on at all anymore. I was just working on it yesterday and it totally turned off (only the power supply led was on after that) and did not respond to the turn on button anymore. I disassembled the [censored] thing but could not notice anything wierd at all yet. I was checking the forum but could not find any relavant yet and there are two many posts anyway. Would any guru be as kind as to briefly list the things worth checking, typical hardware faults and fixes (things like the inductor falloff with the t23)? Is there a picture about fuses?

I would highly appreciate if anyone could help me.
Thank you fellas in advance
