A few days ago my notebook started to bug around with charging the battery. When the battery is not absent notebook runs smoothly. Until I plug in the battery.
Then it starts to charge but immediately stops and restarts charging and stops and so on. If the notebook is not running battery seems to charge well (LED is not blinking). And LED is not blinking intermittently. Seems to be arbitrary.
Does it have something to do with that? This happens every second.
