Hej,na biurko trafił Lenovo B50-80 z płytą LA-B091P ZIWB2, ZIWB3, ZIWE1, laptop ma następujące objawy: po podpięciu zasilania i naciśnięciu power zapal się diodka wentylator startuje, po kilku sekundach wentylator się wyłącza dioda świeci nadal, obrazu brak jedynie jakies regularne prawie niezauważalne miganie obrazu któremu towarzyszy jakiś dziwny dźwięk z płyty, przy pomiarach kiedy to miałem załączoną płytę po upłwie ok. 2 min od włączenia wentylator zaczął działać, po wyłączeniu i włączeniu wentylator się nie wyłączał tylko chodził non stop, po odpięciu zasilania, podpięciu i włączeniu laptopa wracamy do sytuacji wyjściowej, tj wentylator chodzi z 2-3 sek i się wyłącza. Od czego zacząć takie pomiary? Pomiar każdej cewki na płycie i sprawdzenie rezystancji?
