Réponse à : « Why doesn't keyboard and trackpad work after battery replacement? »I had the problem after replacing my battery that the touchpad would move the mouse pointer but it wouldn’t left or right click. I looked at the original battery pack and realized a thin metal covering that went over the touchpad was pulled off when i removed the battery. I pealed it off the original battery and put it back over the touchpad and reinstalled the new battery. It fixed the problem and everything is working well know.
