Model : HP Elitebook 2540P
Board id : Compal LA-5251P
Laptop not power on. When i press power key, laptop power led blink a few seconds and then off. No CPU Fan spin. +5ALW and +3ALW are ok (When i press power key ). But +5VS and +3VS are not found. There is no RUN ON Volt. BIOS flashing is not correct the problem. How can i find the problem device. Please help me.
