Witam
Pacjent to laptop HP Pavilion Gaming 15-dk2803nw z płytą HPT52 LA-L001P po zalaniu. Laptop się po zalaniu miał uszkodzoną jedną kość RAM i korozję w pobliżu układu UV2 (konwerter HDMI PS8209a). W tej chwili laptop się uruchamia działa poprawnie ale potrafi się wyłączyć. Jak włączę stres test to AIDA64 po chwili wykrywa przegrzewanie a wbudowany stres test pokazuje temperaturę rdzeni ok 60stopni i potrafi się po 2-3 minutach wyłączyć. sprawdziłem płytę kamerą termowizyjną i bardzo mocno grzeje się tranzystor PQB01, po chwili od startu ma 90 stopni i rośnie aż do wyłączenia laptopa. Nie udało mi się znaleźć dokumentacji płytę więc nie wiem dokładnie co zasila.
Rezystancja z układu:
1,2,3 - 332kOhm
4- 332kOhm
5,6,7,8 - 353kOhm
