Hi
I have a Lenovo IdeaPad 3 14ITL05 that has suffered liquid damage, when I received the laptop it was able to power on ok but it wouldn’t charge the battery.
There were ares of liquid across the board which I have cleaned and I have replaced the charging IC PU100 (BQ780S) and the 3 mosfets PQ102, P103 and PQ104 involved in battery section.
Upon further inspection a resistor on the SMB_EC clock line from battery connector to EC was damaged so I replaced this and the battery started to take a charge, however it will only charge for around 5mins then it will stop, also there is no orange charging indicator on the laptop.
I have installed Windows on the laptop and when powered on it does not show the charging icon in the system tray, but the battery is still charging due to the current consumption on the power supply being around 2.5a. When just powered on the adapter it is around 1.5a. I have left the laptop over night whilst plugged in and it has charged the battery to 100%, but it still does not show any signs of being detected within Windows.
It is charging but Windows does not recognize it as charging?
Any help would be appreciated, thank you.
