Laptop Trackpad "Jumping" or Erratic
4.5
The cursor moves on its own or jumps across the screen while you are typing.
Symptoms
- Ghost clicks
- Jumping cursor
- Multi-touch not working
Possible Causes
- Dirty surface
- Static buildup
- Swollen battery pushing up
Step-by-Step Fix
1
Clean the Surface
Oils from your skin can build up and cause false touches.
2
Disable "Tap to Click"
Reduces accidental clicks if the sensor is over-sensitive.
3
Check for Battery Swelling
If the trackpad is physically lifting, the battery underneath is likely failing.
When to See a Technician
Using the laptop while it's plugged into a cheap, ungrounded charger can cause trackpad interference.
