Hello
Excuse my English but I am French and I use a translator to communicate with you.
I have a problem with a TOSHIBA C50-B-14F PC.
This is a pc that was unused for several months because it was no longer starting at all, in fact the problem came from the capacitor PCB26 which was in CC, so I changed it and the pc worked again.
The battery being HS, I ordered a new one but impossible to charge it, in Windows the presence AC / battery works but the percentage remains fixed and if I remove the AC power, I have a message "low battery".
So I changed the BQ24735 charging chip as well as PQB01 and PQB02. I tested PQB07, PQB03, PQB04 to the ohmmeter, they look ok. I did a voltage reading attached and everything looks ok too. I don't know what to do anymore, if you could help me it would be great.
