Hi ,
The notebooks sometimes won't post ( powers but no bios ) , when it does it works fine for 5 minutes but then I see minor display interference and then it freezes ( perfect display back to normal just stuck ) .
After that its hard to make it boot again .
Heres what I found :
1. There is a humming/low buzz sound from the power board even if its off or disconnected from the AC .
2. If I press the reset hole on the bottom I can shut it down and boot again .
What do you think ? power board ? grounding ?
Thanks in advance ,
Gil
