laptop Toshiba satellite U400-13n c.i. ISL88731hrz defect


Recommended Posts

va salut, am la reparat laptopul de mai sus, am gasit ISL88731hrz defect, pin 21 VDDP scurt la masa, dupa ce l-am scos pare ca porneste se aprind niste leduri dar ventilatorul se opreste dupa citeva sec., e clar ca fara acest circuit nu va merge desi are rol de incarcator baterie - fiind alimentat acum direct din adaptor fara baterie cuplata, exista posibilitatea sa mearga si fara acest circuit ?
