Good afternoon friends of the forum, this laptop has the defect that does not turn on and the power supply connector does not switch on the white LED.
I tried several original hp power supplies but nothing.
I tried to rewrite the kbc eprom and bios eeprom but nothing.
I checked the motherboard under the microscope but not found trace of oxide. I did checks resistence in the coils without finding shorts.
Checking the PL11 coils I find 3.30v but on the coil PL801 I find 0v.
Checking the resistance on the coil PL801 I find 20 kohm
