Lenovo Ideapad S10-2: How to fix battery life problem?

Question

Iron

There is a netbook Lenovo Ideapad S10-2. At one point it stopped working on battery power. The battery is charging, the battery status is monitored, but when you turn off the power supply, it immediately turns off. Tested on two different batteries, one original Lenovo, the second noname, the result is the same.
I didn't find anything useful on google.
Maybe someone knows how to fix this?

Answer 1

It is necessary to check the circuit responsible for switching the power - "charger" (charger).
