HP Elitebook Folio 9480m power issues

[classicandy]

Hi

I've got this HP Elitebook Folio 9480m that when I press the power button, the power led comes on and turns off at approximately 8 seconds while the WiFi led remains On and the Fan continues spinning at high speed.

The system powers on immediately the adapter is connected (without battery) even though the CMOS battery isn't weak..... There's no display too.

Different RAM modules have been tried.
WiFi card has been removed
CMOS battery has been changed/removed

BIOS hasn't been reflashed/changed though

Any ideas from experience on what can be the problem?

I've fixed it already..........

Just a broken resistor between Q7056 [Pin 2] and Q2971 [Pin 3]. I just replaced it and it works now.
