Hey ,

This one 1st time come with a bubble on u3200, i replace that one and go to the client but after 7 days comes again!

I replace again U3200 and the machine comes to life again! when I start assembling the mac i noticed that mac don't show image.

Now when i plug the charger or battery the machine start without press the button on/off. I see that the fan spin and after 10 sec stop but still working!

i already replace u3100 + u3200 again and tied new bios but same history!

any suggestions ?

thanks

U3200 burnt two times can be sign of chinese charger.

Do you get USB activity now, only missing image?
Check SMC_LID signal.
