820 01700, strange problem if i hibernate the machine from system

[SpinNNN]

hey guys,

This one came with a C9080 shorted. After replace the capacitor the machine turn on and work well..
But if i set on system hibernate and try wake up the machine press a key or click on trackpad the machine restarts give me a kernel panic. This is the only problem..

If i close the lid and open, works fine.. The machine only restart if i set on system to hibernate.. Strange one!

I already test the motherboard in 2 a2141 chassis. Same problem.

I already compare the readings on J4802 to a working board and is the ~same.

the only line that I think has a problem is PPBUS_G3h:

reading diode mode: 0.360V
I measure 2 same board with: 0.420V

But i already spec the motherboard for missing components and its all ok.

Need some directions.

Thanks

Post your kernel panic.
Also test leaving the lid closed more time, allowing the machine going to hibernate, not just suspend.
Be sure both angle sensors react correctly.

Good evening,

I've been on vacation and just got back.

the kernel error is in the pdf.

leaving the mac with the lid down for longer ends up causing the same problem when I lift it.

I replaced the u6650 and u4802 to no avail, but the same problem remains.
I've got another model of the same model on the market that I need to repair the motherboard and then I'll buy the measurements for both angle sensors.

Thanks

In my case, reinstalling a clean system with full formatting helped on this board.
