Hi everyone!
I have a problem the HP 4520s that is not powering up.
I have measured the regulator voltages and they are ok 3,3V and 5V
Then I have checked the charging chip and everything was ok except the acdetec there should be at least 2.7 V for the chip to detect the main power but there is 0. Then I have checked the resistors capacitors and transistors where the acdetect comes from and all seems to be ok.
If someone had this problem any suggestion would be apreciated.
The Main board is H9265-1
