La acest laptop am observat ca s-a mai lucrat pe langa controller-ul MAX1772,m-am uitat mai atent si am observat ca nici invertorul nu se aprinde,se aprinde doar ledul albastru de pe butonul de start si ce-l de la wirless dc apas pe buton.in momentul in care apas butonul de start pleaca ventilatorul si atat nu apare nici imagine nici lampile nu se aprind.poate fi defect Max 1772?in afara de tens de 19v nu mai iese nici o tens din el.
