HP 850 G1 - Information on 2 chips ?

[Acnologia]

Hello,

Just to verify 2 small problems.

Bought unknown condition 850 G1 on sale.

Removed the board from the entire housing.
Plugin power (genuine HP) CPU heats up , no lights ,nothing, not even fan spin...


Will check first BIOS.

But clarification ,is needed.

U366 is BIOS Region?
U365 is ME region ?

Update.

I've tried all the BIOS Dumps i find here, and the laptop went to "stable" mode light power on.

So the power on light remains on no blinking
No sound
No image
No fan spin

But the CPU is getting hot...

Any suggesitons?

If the PCH is getting hot without pressing the start button its dead.

If you turn it off, and it stays off, the laptop remains cool.
You press the power button ,everything heats up but nothing on screen.

The "fault" of turning on without pressing the power button was because i didn't install CMOS battery (so as soon as i plugged in charger ,then it automaticcally was turning on).

Right,now youve made it clear. Post the orginal bios backups,the serial number on the case and the motherboard part number

Thanks a lot SMDFlea!
But nothing, at least now it "turns" on ,when i want it to turn on . and not by itself.
Lights go on , fan spin , no image,and i hear a really high pitch noise, but cannot find where is the problem...
