re-calibrate the digitizer pad.
Explanation:
According to my research on information technology, I can say that based on the information provided within the question in order to fix this issue, you need to re-calibrate the digitizer pad. This is because over time, these pads can develop input drift which causes this to occur. This is easily fixed be running a re-calibration program within the notebook, to make sure the input is precise.
