#1 Toshiba L50-B-1CE DA0BLIMB6E0 rev: E, działa na zasilaczu, z baterią martwa

Dzień dobry,
Mam toshibę jak w temacie. Klient zakupił baterię w greencellu i jak nie działała to wymienił na kolejny egzemplarz. Z baterią komputer nadal nie włącza się.
Na samym zasilaczu działa poprawnie. Nie potrafię namierzyć usterki. Brak schematu. Mam obok płytę działającą którą mogę się wspomóc częściami i na której sprawdziłem baterię - działa poprawnie, komputer działa na niej i ładuje się. Sprawdziłem ILS88732, PQ15, PQ16, układ KBC, bios.
Może któryś z kolegów mnie naprowadzi?

a) Battery + power supply connected.
b) Battery only (without power supply).
c) Power supply only (without battery).

Does the machine stay turned on and works on battery, if you disconnect the power supply, when the machine is turned on?

Install a Battery Mon software and post a screen of "Battery Info", when the battery + power supply are connected.

Turn on the machine with power supply only and connect the battery to the board, while the machine is turned on.
Run a "Battery Mon" and post a screen of "Battery Info" in this case.

Do you have an oscilloscope?
If so, measure the voltages to ground on pins 9, 10 of charger chip with oscilloscope with original and replacement battery.

Measure the resistance to ground on pin 6 of battery connector.
