HP Pavilion 15 noreaction to power button
Hi everyone,
I have little complicated issue motherboard issue with HP Pavilion 15 from my friend.
Board doesn't react to power button. It's only signalized the charger was connected and/or acumulator charging.
I found schematic for my board, so I checked button connection to KBc and main supply. I found the MAINON stay low/gnd after power button push. So processor and other components has no power.
I have suspicion to faulty KBC circuit but I'm newbie so I need to know if this faulty is possible.
My motherboard
Model: R62 rev. E
DAOR62MB6E1
KBC chip is KB394OQ A1 (unfortunately I can't found datasheet)
KBC is on page 30 in schematic PDF
My questions are
- is it really possible to fail KBC with these symptoms?
- is there some certain method how to test it?
- is neccesary reprogram KBC if I will buy new one from ebay?
Thank's a lot for answers and hints
