Hello friends,
I have this laptop with a not charging battery. This is the 3rd same laptop with exact same problem so there must be some manufacturing design problem. Windows says 0% (plugged in) and percentage doesnt increase. I tried with new battery and also with new BQ24780S charging IC. Laptop works only on DC power, after unplug immediately shut down.
I measure BQ24780S with and withou battery and here are the results :
without battery / with battery
1 19.28 19.28
2 19.25 19,25
3 18.80 18.75
4 24.71 24.26
5 5.98 5.67
6 2.63 2.62
