poplex22 Posted August 9, 2019 Share Posted August 9, 2019 - am urmatoarea problema : 1. - laptopul cu bateria si adaptorul conectate incarca sistemul apoi la citeva zeci de secunde cade brusc si restarteaza si secventa se reia de 3-4 ori apoi se blocheaza si nu mai asculta nici-o comanda. 2. - daca laptopul este conectat doar cu bateria nu mai sunt probleme. 3.- daca laptopul are bateria scoasa si este conectat doar pe adaptor apar din nou problemele cu restartarea identic ca la pct. 1. - va rog citeva solutii tehnice ?

poplex22 Posted August 12, 2019 Author Share Posted August 12, 2019 va multumesc pt. raspuns, nu gasisem aceste comentarii : - vad ca problema se rezuma la 2 posibilitati ; 1. trebuie incercat un update de bios, 2. exista o deficienta de sistem pe win 7 legata de power option ac/dc - am facut niste masuratori pe MB si tensiunile ar fi normale +5vcc. +3,3vcc, testul nu le pot masura pt. ca dupa apasarea pe butonul de pornire dispar imediat, ce mi s-a parut suspect este o rezistenta f. mica fata de masa la tensiunile +Vccp cam 10ohmi si la +Vcc_core cam 5ohmi ?! , citeva comentarii va rog Quote Link to comment Share on other sites More sharing options...
poplex22 Posted August 12, 2019 Author Share Posted August 12, 2019 - mentionez ca cei 5ohmi la +Vcc_core fata de masa devin sute spre 1kohm atunci cind scot procesorul , cred ca acelasi lucru se intimpla si cu +Vccp fata de masa cu chipsetul video decuplat de MB pt. ca +Vccp alimenteaza pe linga procesor si partea video Quote Link to comment Share on other sites More sharing options...
