Toshiba WT8-A
PCB: T8T_MB V5.0 20130929

Nie ładuje i nie pracuje na baterii. Bateria nowa, jest widoczna w systemie, w systemie informacja "Podłączony ładuje" i wygląda że po podłączeniu bateria się rozładowuje, podpiłem zasilaczem do 2% i po paru minutach pracy w systemie spadło do 0.5%
Na samej ładowarce działa.

Pobór prądu w stanie czuwania 120mA
Pobór prądu podczas pracy zaleznosci od obciazenia 200-800mA


Charger BQ24192I.
Na cewce od chargera mam 90Ohm

Napięcia na złączu gniazda baterii z wpiętą baterią to:
3.3V
3.3V
3.3V
3.3V
0V
1.8V
1.8V
2.3V
0V (GND)
0V (GND)
0V (GND)
0V (GND)

Co mogę sprawdzić? Czy wymieniać charger?

Hello!

Measure the voltages to ground on all pins of battery connector with and without connected battery (charger connected all the time).

Install a BatteryMon software and post a screen how it detects the battery ("Battery Info" button) with connected charger + battery.
