I have HP dv5-1225ee (DAQT6GMB8B0) freezes it self at POST screen.I flashed the BIOS with latest update but nothing changed.If i pressed "Esc" button from the beginning of power up nothing showed but if i do nothing then it shows POST screen and froze.
01. I changed RAM
02. Remove all the attached devices
03. Re flashed BIOS with latest update.
04. Replaced new RTC battery.

Someone please tell me where dig for a solution....?

Update:

KB3926QF heat badly when laptop is powering up.I dont have spare new KB but i have another one on damaged MOBO.
Shall I try it with this one or do i need to check why is this KB heating?

Friend these machines have trouble soldering the processor socket
makes a test linking the machine by pressing the processor against the mother board
often is also the chipset video call also try pressing it.
