Sony VPCF239E (MBX-243) Turns On then Off after 5 sec

P.zonouz

Laptop brought with this symptom: Turns On when you press the power switch but goes off after 5 seconds. CPU changed, Bios sewed and is true, Hub( HM65) changed, but symptom is exactly same. What is your suggestion?

I changed KBC too. and bios with new bios (true one). But everything exactly same. Turn on consumes 0.45 ampere and keeps on till 6-7 seconds then goes off.

First of all - check all voltages, enable signals, power goods, check power key, reconnect (and check voltage) a RTC battery. If it is ok - see LPC for activity. And so on.
