BQ8030A Lenovo x220 battery

Postby videosony » Wed May 17, 2017 5:22 pm

Hello

Can you check my log from lenovo battery?
I do not see error flag, battery has no voltage on battery pins (0V), cells OK, fuse OK, only 94 cyclesCount.
One FET is open, FET two is closed - no signal on gate, FET is ok.
Do i need reset battery or is hardware error?

Thanks

Most likely you need to connect SYS_PRES pin to GND on battery terminal to get the voltage.
Or simply insert battery in laptop.

It is disigned for safity reasn to not have valtage on battery terminnals when battery is out of laptop.

Laptop with battery do not power on, only with adapter 220V.
I see on windows PLUGGED IN, NOT CHARGING and 90%, when i remove adapter from laptop, laptop turn off.
I have try to connect sys pin with gnd, but also no voltage on battery terminal.
