If the touchpad is already turned off, the next likely causes are touchpad driver behavior, gesture settings that may still be active, or another pointing device/software sending input.
Try these steps in order:
- Check touchpad settings again
Go to Settings > Bluetooth & devices > Touchpad.
- Lower Touch sensitivity if the setting is available.
- Turn off Tap gestures.
- Turn off Three- or four-finger gestures.
- Reinstall the touchpad driver
- Press Windows + X and select Device Manager.
- Expand Mice and other pointing devices.
- Right-click the touchpad device, such as Synaptics, ELAN, or Precision Touchpad, and select Uninstall device.
- Restart the PC.
- Check for Windows updates Go to Start > Settings > Update & Security > Windows Update and install the latest updates. Missing updates can affect keyboard, mouse, and special key behavior.
- Check for accidental gesture or search triggers If Windows Search opens unexpectedly while typing, a three-finger touchpad gesture may be firing. Go to Start > Settings > Devices > Touchpad and change the Three-finger gestures tap action from Launch Windows Search to Nothing.
- If using an external mouse, check its software If a USB or wireless mouse is connected, its software may have sensitivity or gesture settings that can cause unexpected pointer movement. Reduce sensitivity there if that software is installed.
- If the issue happens mostly in Word and text is overwritten
Check whether overtype mode is on:
- In Word, go to File > Options > Advanced.
- Under Editing options, clear Use the Insert key to control overtype mode and Use overtype mode.
If the cursor still jumps after these steps, test with the touchpad disabled and the external mouse disconnected. If the problem stops, that points to a driver, gesture, or hardware input device issue rather than the keyboard itself.
