poplex22 Posted February 6, 2021 Share Posted February 6, 2021 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 ? https://pdf1.alldatasheet.com/datasheet-pdf/view/745511/INTERSIL/ISL88731HRZ.html Quote Link to comment Share on other sites More sharing options...

modoran Posted February 6, 2021 Share Posted February 6, 2021 Se gaseste la mouser de exemplu, in jur de 25 de lei + transport din SUA. Peste 250 de lei e transportul gratis de acolo. Quote Link to comment Share on other sites More sharing options...
