Am un laptop Lenovo G580 model 20150, cu proc Intel, al unei conostinte.

Acum cateva zile a vrut sa-l conecteze la TV cu cablu hdmi si a facut flama, stricand si televizorul si laptopul.

Mufa Hdmi a laptopului este topita pe jumatate in interior, televizorul nu l-am vazut dar si ala e afectat.

La pornire laptopul da pt cateva secunde u ecran alb, seinvarte ventilatorul, porneste hdd, incearca de cateva ori sa porneasca dar apoi se opreste.

Am scos mufa afectata si degeaba.

Pe placa sunt prezente toate tensiulnile si semnalele de la PCH la chipul de pornire KBC (ENE), la bios, etc. Am 19v, 3,5v si tot ce trebuie.

Ce am observat este ca chipul PCH se incinge f tare inca din prima secunda de cand incearca sa porneasca.

Sa se fi corupt biosul? Sa fie de vina placa video sau PCH-ul?
