Try each step and check if your touchpad issue is resolved. If the issue is not resolved, proceed to the next step.

Fix 1: Ensure that the touchpad is turned on

There may be times when your touchpad is turned off due to the settings on your computer, such as when an external mouse is connected.

1. Press and hold the Windows key (Windows Button), and then press the Q key.
2. In the Search box, type Touchpad.
3. Touch or click Touchpad settings (System settings).
4. Look for a Touchpad On/Off toggle.
5. Touch or click the Touchpad On/Off toggle to turn the touchpad on or off.
   NOTE: The preceding steps apply to Windows 11 and 10. For other Operating Systems, see Dell Knowledge Base article Disabling or Enabling the Touchpad on a Dell Laptop.

Fix 2: Ensure that the touchpad is clean

When the touchpad has any dirt, grease, liquids, or food on it, it may prevent the touchpad from recognizing your finger (the touchpad must make good contact with your finger to work correctly).

For more information, see Dell Knowledge Base article Guidance for Keeping Your Dell Technologies Equipment Clean.

Fix 3: Save any data, close any open programs, and restart the computer

Restarting the computer clears out the computer memory and resets the connection between the computer and the touchpad.

1. Save updates to any open documents.
2. Close any open programs or applications.
3. Select the Start icon.
4. Select the Power icon.
5. Select Restart.

Check to ensure the touchpad is working correctly after the computer completely finishes booting.

Well I will suggest you to Update your laptop drivers.

Laptop drivers do not get updated. They are customized by Dell to work on the Dell board. Dell will update if it is ever needed.
