Laptop od młodego sąsiada ma ponad 2 lata i kupę kurzu na radiatorach. Po wciśnięciu power zapala się dioda i nic po za tym po przetrzymaniu kilku sekund dioda gaśnie. Baterię ładuje. Pobór prądu bez baterii 0,02A po wciśnięciu przycisku żadnej zmiany.
Brak zwarć na cewkach, na cpu 7ohm grafika 0,3ohm po zamrożeniu 0,7ohm.
Napięcia +0.75VALW, +1.8VALW, +3VALW, +5VALW obecne.
Nie startuje +1.8VS_AON z powodu niskiego stanu PXS_PWREN, ale gdy mu zapodam 1,8V, +1.8VS_AON ruszy ale nic to i tak nie zmienia. Napięcie na SPI obecne bios z internetu podmieniałem ale bez zmian.

Cześć,

Zmierz napięcie i rezystancję do masy na PL500.

Wychodzi że uszkodzona grafika lub procesor jednego dnia uruchomił się podgrzewając nieco procesor, innego już akurat podgrzewając grafikę, dziwny to przypadek.

Spróbuj docisnąć grafikę i wtedy odpalić. Coraz więcej przypadków jest pękających kulek pod GPU kilka miesięcy po gwarancji. Nawet na youtubach już o tym mówią, że taka jest tendencja.
