HP ProBook 6560b

[me.hoonigan]

Hi. I have a HP ProBook 6560b that turns on automatically after you insert either the battery or AC adapter, then it would display the HP logo (Not always) for a few seconds and just power down. I've tried removing HDD and RAMS even the CPU or even tried with the motherboard alone but still does the same thing. I've thought maybe it could be that the power button is stuck, could this be or is it something else. Thanks.
