Witam, laptop jak w temacie.
Płyta LA-L171P
Stara bateria pokazuje 12,4V jednakże w systemie widnieje 0% i jej nie ładuje oraz na niej nie działa.
Wymieniona na nowy zamiennik, ładuje ją, i na niej działa lecz nie do końca. Mianowicie, czasem działa dobrze czasem kilka sekund lub minut mimo, że jest naładowana na 67%. Jak się na niej wyłączy nie ma możliwości odpalenia laptopa bez kabla.
Napięcia na baterii bez zasilacza:
1-4 - 11,98V
5 - 3,25V
6 - 3,25V
7 - 0,15V
8 - 0V
9 -12 -0V
Napięcia na baterii z zasilaniem:
1-4 - 12,67V
5 - 3,22V
6- 3,22V
7 - 0,17V
8 - 0V
9-12 - 0V

Hello!

Measure the voltages to ground on both pins of resistor PR203 with and without the battery connected (power supply connected all the time).

Z baterią podłączoną od strony złącza baterii: 0,15V, z drugiej strony 3,27V
bez baterii od strony złącza baterii 3,20V, z drugiej strony 3,27V
Opór na PR203 mam 100kΩ a wg schematu powinno być 200kΩ
