verifica daca exista tensiune de 19v pe intrarea circuitului convertor pentru  tensiunile  de  stand-by 3.3v si 5V TPS51120RHBR (PU3 in schema)

Am verificat tensiunile si se pare ca pe bara de 3,3v am un scurt.Din cate am inteles de la client a vrut sa alimenteze laptop-ul pe pinii de la baterie si asa s-a busit.Am renuntat sa-l mai repar deoarece poate fi dusa orice piesa care se alimenteaza cu aceasta tensiune.

mai ales daca a pus polaritatea invers cine stie ce a busit pe acolo singura solutie alta placa

Salut! Am postat aici. Sony Vaio PCG41213M (VCCSB). Pass bios, pass ssd cu truecrypt. Am incercat programe din Hiren's, l-am desfacut, scos bateria de bios, nici-o schimbare. Se poate adapta alt hdd?

Bios cu H2o cu uefi, dar booteaza de pe 1cd, 2hdd. Tnx, PM!
