Lenovo Ideapad 330-15IKB
Płyta EG523 EG524 LM-B453 rev.1.0
Procek SR3LA
ATI 216-0889018

Po czasie zaczyna migać ekran na czarno i się wyłączy laptop (pobór prądu 23mA), po chwili znowu można go włączyć.
Objawy są w systemie i w menu bios takie same. Grafika ATI w biosie była wyłączona i objawy te same. Bios podmieniany. Ram podmieniany. Napięcia ok.
Proszę o podpowiedź jak wyłączyć RAM na płycie (zdjęcie), podejrzewam że one wariują. Wszystkie solucje z internetu próbowałem, ale to nie wyłączyło RAM. Schemat mam z wersji rev.0.1 i możliwe że coś nie pasuje.
Proszę o pomoc w naprawię.

Jeśli odciąłeś ATI i RAM na płycie to został Ci tylko jeden układ...
Bo rozumiem, że bID6,7 11 masz ustawione.. i bez kości nie startuje a z kością tak?
