Hello everyone,
I have a HP 14, motherboard model LA-A994P. When I plug the charger there is charging light present. When I try to turn in on, the power LED turn on then turn off in about 1 second and stay off.
I did check the voltages in PU301 (IC RT8243AZQW page 37 of schematic), 3.28v and 4.58v (picture attached)
No voltages in @PJ302 (should be +3valw) and @PJ303 (should be +5valw) in page 37 of schematics.
What else should I check, how do I do it?
is PU301 ok with 4.58v?
Thanks in advance.
Mario
