Model - Lenovo Q190
Płyta - BM6C66 VER1.0
Most - SLJ8E
CPU - SR0U3 (i3-2365M)
Komputer po naciśnięciu włącznika pobiera około 750mA, następuje restart i proces powtarza się od nowa.
Wszystkie napięcia pojawiają się oprócz napięcia na przetwornicy PU9- ISL958SSHRTZ ( oporność tej gałęzi to około 14 omów)
Bios programowałem wsadem umieszczonym przez kolegę Vogelek23, jak i wsadem z internetu. Nie znalazłem wsadu dokładnie pod ten cpu, nie wiem czy to ma znaczenie.
Ram mam LV więc to też wykluczyłem.
Nie wiem co myśleć o PU9, bo ona startuje jako ostatnia.
VR on pojawia się 3,3v ale przetwornica nie startuje.
Przed chwilą podczas pomiarów wystartowała więc podłączyłem monitor ale nic na nim się nie pojawiło.
