Re: HP Probook 455 G1 BIOS and schematic needed

My problem is - whech attach power adaptor, laptop power up itself, leds light up, after a while full speed of fan, but without some more heating on cpu or amd chipset or some other part.
Changed CPU (A4 for A6 series, don't have any A4 on stock), reballed chipset 218-844012, flashed BIOS, changed KBC but still the same.

Can anybody post here schematic please?

Or some suggestion what to do?

Found a solution?

Re: HP Probook 455 G1 BIOS needed

Unfortunatelly not. I found faulty CPU, when changed, few days laptop worked, but now same problems again.
Moved to the store and waiting for some idea.

I noticed that it is not working without BIOS battery. Battery holder was broken, changed it and now testing. Turns on with no problem for few days.
