Sure, the drivers are there, see photo. I can leave the charger connected for many hours but the battery charge percentage does not increase. With the laptop turned off, I disconnect the battery, reconnect it again and the charging percentage increases to 77%. I did another test, I charged the battery using the original charger and its voltage was 8.65 volts, I disconnected the battery and manually unloaded it with a resistance of 20 ohms to have a current of 400 ma and the battery lasted 9 hours until reaching its nominal voltage of 7.6 volts. I think the battery is fine, but I do not know why the load indicator in Windows is crazy and I turn off the laptop.
