Dzień Dobry

Model: HP Pavilion 17-cd2254ng
Płyta: LA-011P REV 1.0

PL302 - Mohm
PL301 - Kohm
PLB(8)1 - Mohm
PLM1 - 400 ohm (przetwornica RAM, bez RAM)
PLZ1,2 - 38ohm
PLG1 - 120 ohm
PLV1,2,3 - 0,5 ohm
PLW1 - 40 ohm
PL801 - 600 ohm

20V jest. Brak 3.3/5V, LDO 3.3V obecne na KBC.
Generalnie laptop miał zalanie w okolicy KBC, oczyściłem. Nic nie jest zjedzone.
Laptop przez diagnozą uruchamiał się, ładował system, podczas logowania wyłączał się.

Obecnie jest brak reakcji na przycisk, nie mam schematu ani boardview i jest ciężko coś tutaj dla laika dalej szukać.
Proszę o wsparcie.

BTW. Najlepszego w Nowym Roku !

Dzięki.
