Acer Aspire One ZG8 nu porneste HDD nu se aprinde ecran,

La apasarea butonului power se aprinde Led-ul de power, clipesc scurt cele 3 Led-uri din stanga deasupra tastaturii si ventilatorul porneste scurt, apoi se opreste ... dupa incalzirea CPU circa 3 - 5 minute , ventilatorul porneste ...

Incarcarea functioneaza normal , bateria este aproape noua ...


Dupa demontare am gasit zona din imagine oxidata - corodata si R266 intrerupta .... am curatat zona , schimbat rezistenta 16Kohmi , verificat continuitatea traseelor ... totul este Ok ...

Am verificat alimentarile

VCC_CORE + 0.95 V

HDD este testat Ok .. 


Manifestarea este aceasi ... se aprinde Led-ul de power si atat.... la apasarea lunga power, Led-ul se stinge ... la apasare porneste din nou ... 


Ce anume se mai poate verifica la aceasta manifestare ??


Multumesc celor care ma pot ajuta si imi pot da ceva informatii .

ai incercat sa pui monitor extern, pe vga, sa vazi daca are ceva semnal acolo?

eventual poti incerca cu un stick de USB bootabil, dar daca nu vezi nimic pe ecran, nu cred ca ajuta.

am unul la fel, si nu am probleme tehnice cu el, doar estetice, un plastic lipsa si camera nu o recunoaste in sistem, tot apare disconnect din cand in cand la usb camera.

daca nu reusesti sa-l faci, as putea fi interesat macar de un plastic :)
