BKOFF# = 0V
+LCDVDD = 3.3V
+3VS = 3.3V

Sprawdzałem power sequence:
+Vcc_core =1.04V
PLT_RST# = 3V
H_CPUPWRGD = 1V
PCH_PWRGD = 3.3V

SM_PG_CTRL = 3.3V
VR_ON = 3.3V

Próbowałem inną kość ram a także czyściłem slot.

Wygrywałem różne wsady działające z internetu oraz wygrywałem orginalny ze strony producenta i dalej nic :(

Chyba że bez działającej bateri nie ruszy bo laptop się wyłącza po odłączeniu zasilacza na bateri a podobno działał na samej bateri

Na stronie producenta w zakładce biosów najstarsza wersja pisze coś takiego "Resolve system can not resume when battery under 6%"
Mam rozumieć że bez baterii głównej sie nie zapostuje bios?
