Steps To Fix Laptop Touch Pad
- Fn key combination
- External device
- Check touchpad settings
- Checking Device Manager and updating drivers
- Check BIOS setup
- Corrupt operating system files
- Defective hardware
Fn Key Combination
Some laptops have a Fn key + function key combination to enable and disable the touchpad. If you have this feature on your laptop, press the button or keys to turn the touchpad on and off a few times.
External Device
Some USB input devices automatically disable the touchpad when connected. As a repair step, turn off the computer, disconnect all external devices, and then restart the computer to make sure that one of them does not turn off the touchpad. If this fixes your problem, you can reconnect the USB device to continue the adjustment or modification discussed in the following sections.
Check Touchpad Settings
Look at your mouse / touchpad settings because they may not work on your touchpad or may disable the touchpad completely. To access mouse settings, follow the steps below.
Windows Users - Touchpad Settings
- Press the Windows key, type touchpad, and select the Touchpad settings option in the search results.
- In the Touchpad window, make sure the Touchpad On/Off toggle switch is set to On. If it's Off, change it to be in the On position.
Windows Users - Mouse Settings
- Press the Windows key, type Control Panel, and then press Enter.
- Click the Hardware and Sound option.
- Under Devices and Printers, click the Mouse option.
- Ensure there is a check in the box next to Enable touchpad.
- Adjust any other settings to your liking, then click Apply, then OK.
- Test your touchpad.
If you do not see a touchpad tab in the Mouse Properties window, try the following steps.
- In the Mouse Properties window, click the Hardware tab.
- Check for an entry in the Devices list named HID-compliant mouse. If you have a USB mouse connected to your laptop for troubleshooting purposes, you may see two HID-compliant mouse entries. Click on each entry to find the one that does not have USB in the Location property.
- When you find the HID-compliant mouse entry for the touchpad (the non-USB entry), click the Properties button.
- In the HID-compliant mouse Properties window, check the Device status to see if it states, "This device is working properly." If it states anything else, then there is a problem with the touchpad.
- If the touchpad device is not working properly, you can try updating the drivers. Click the Change settings button, click the Driver tab, then click the Update Driver button. Click the Search automatically option to allow Windows to look for an updated driver on the computer and on the Internet.
Apple macOS users
- For macOS X, access the System Preferences in the Apple menu at the top of the desktop screen. For MacBook Pro, click the System Preferences icon at the bottom of the desktop screen.
- In the System Preferences window, click the Trackpad icon to open the Trackpad settings.
- Adjust any trackpad settings you prefer to change.
- Test the trackpad to see if it works.
Checking Device Manager and updating drivers
If the touchpad is not working yet, Windows Device Manager can tell you detailed information about hardware issues and help update drivers. For example, if there is a yellow exclamation mark or red X next to it, there is a hardware or software problem. To find the touchpad in Device Manager, follow the steps below.
- Press the Windows Key and type device manager, then press Enter.
- Under Your PC, the touchpad is either going to be listed under Mice and other pointing devices, or under Human Interface Devices. If it is listed under Human Interface Devices, it will likely be listed as HID-compliant touchpad, or similar wording. Double-click one of the two to locate the touchpad.
- Locate your touchpad and right-click the icon and select Update Driver Software.
Check BIOS setup
Make sure the touchpad has not been disabled in the BIOS setup. Once in BIOS setup, check the hardware device settings and if the touchpad is disabled, re-enable it and restart the laptop.
Corrupt operating system files
Another reason for a malfunctioning touchpad is corrupt operating system files. When you notice other issues due to corrupted system files, the touchpad will not work.
To fix this, you need to activate the restore point on a date to stop the touchpad from working, or you may need to perform an operating system repair installation. You may need to access the reset partition on the hard disk or use the operating system installation disk for a repair installation.
Defective hardware
Finally, if the touchpad still does not work properly or after trying the above adjustment steps, it may still be defective. Contact the computer manufacturer for further recommendations or take the laptop to a computer repair shop. For this you need to replace the touchpad or another hardware component. If the touchpad cannot be adjusted, you can use an external mouse attached to a workbench.
