Edy Turnas: Hello I have an acer aspire one 725 0412, when I plug the adaptor the laptop work normally, but the battery doesn't recharge, a message "battery 0%available, plugged in but not charging" appear. I went to Device manager, battery , uninstalled drivers and reinstall but was the same. I bought a genuine brand new battery and nothing change. I measured the adapter and was fine, and the laptop work normal with it.
Can you tell me if I measure the battery connector on my laptop, which ammount of volts is the normal number to read?, because I measured and the maximun was 3.36 per each contact. Do you know what can I check ?Appreciate your help.
