Laptop HP Probook 650 G1
Płyta 6050A2566401-MB-A03 (HSTNN-I15C-D)

Laptop po upadku. Działa na baterii. Brak jest ładowania po podpięciu zasilacza, Nie działa bez baterii.
Podpięcie zasilacza powoduje mruganie diody na włączniku (równomiernie mniej więcej co sekundę).
Da się usłyszeć delikatne kliknięcia.
Napięcia:
3,3V na L6100 - Obecne
5,1V na L6150 - Obecne, ale podczas pukania jakby delikatnie pulsowało
L6150 -
przysiada także napięcie 20V mierzone np na PAD6110 czy PAD6015
Podałem około 3,5V z zasilacza serwisowego na PAD6150 - i jedyne co się grzeje to U6100
Po podaniu napięcia na PAD6015 - nic się nie grzeje.

Proszę o pomoc w dalszej diagnozie.

Hello!

Measure the voltages to ground on pins 1, 4, 5 of transistors Q6010, Q6011 with the power supply connected only (without the battery).
