Fujitsu v5535 - aliemntare in scurt

Recommended Posts

Guest sumer

Am un notebook Fujitsu v5535 "mort". Tensiunea de 20 V din alimentator scade la 3.3 V (masurat inainte si dupa F1 de 5 A) si alimentatorul intra in "avarie". Mentionez ca fuzibilul F2 (7A) era ars. Ma poate ajuta cineva cu o strategie in a depista defectul si a-l repara. Doresc sa invat si voi aprecia sfaturile la obiect. Multumesc anticipat! :sparge:

masoara daca ai scurt acolo unde scrie DCIN , pe acolo iese curentul din acumulator sau din electronica asta ( cand acumulatorul e descarcat ) spre restul aparatului . Siguranta ce s-a ars e in serie cu acumulatorul , inseamna ca debitat prea mult curent

Multumesc. Am scurt intrucat se descarca acumulatorul rapid la conectare (am pus temporar o siguranta pe locul F2 (7A). :ciuda:

Poate fi o piesa marunta in scurt , de pilda un condensator , ramane sa identifici exact masurand

Corect! Era un condensator SMD scurtcircuitat. L-am inlocuit si laptopul functioneaza deja de "anul trecut"
