Even when the battery is ok and fully charged, instabilty can happen, when the sender and receiver frequency drift away. This drifting can happen, when frequency related parts like condesors loose capacity, when semiconductors fail or other parts changes. If there is no wireless hardware connected, check if the touchpad of the notebook is clean, testwise disconnect it from the mainboard and see, if the issue appears again. Just my ideas, I may be completely wrong. Good luck!
