cel mai posibil placa baza defecta

, defect specific acestui model , procesor in scurt sau deslipit  , controlati sa nu fie scurt pe alimentarile procesor  1,2v si 3,3v

Alimentarile procesorului  de 1.2v si 3,3v nu sunt in scurt .

La punerea in functiune tensiunile sunt corecte si sursa are un ciclu de functionare de 15min dupa care semnalizeaza ledul de doua ori in continuu si tensiunile dispar la procesor.

Acest ciclu de circa 15 min  se manifesta astfel led de stby stins si la apasare pe orice tasta licare , tensiunile cad dupa 2sau 3min si revin imediat si o tine tot asa in cele 15min de la pornire ,procesor cald in tot acest timp ,dupa cele 15min  procesorul se raceste .

Eu cred ca ai 2 variante aici. Fie dump NAND alterat, fie bile dezlipite sub procesor.

Bineinteles, daca tensiunile sunt corecte.
