FIX: Touchpad Not Working on Windows 10
While using your laptop’s touchpad, if the device fails to respond, the cursor behaves erratically, or you can’t get specific gestures tо register, incorrectly configured settings and oυtdated/corrupt drivers may be the reason. Similar problems can also оccur with external touchpads.
Work your way through the troubleshooting tips below to fix issues with touchpad not working in Windows. Meanwhile, you could connect an external mouse or activate Mouse Keys to navigate the operating system.
1. Turn On the Touchpad
Your laptop may have a special key that enables and disables the built-in touchpad. It’s usually mapped to a function key (such as F7 on Acer laptops), and you could’ve toggled it by accident. Press it and check if you can then move the cursor around.
If you use an external trackpad device with your Windows 10 computer, look for a power switch and make sure it’s set to On. Additionally, if the device uses a wireless connection, you must ensure that it’s fully charged.
2. Enable Touchpad in Windows 10
You’ll also find an option capable of turning your touchpad on and off within the Windows 10 settings. Check it out.
1. Open the Start menu (or press the Windows key) and select Settings.
2. Select Devices.
3. Select Touchpad on the sidebar. Then, make sure that the switch underneath Touchpad is active.
Additionally, the Touchpad settings screen features Leave touchpad on when a mouse is connected. If your computer deactivates the touchpad whenever you connect a mouse, make sure to enable it.
3. Review/Reset Touchpad Settings
The Settings app in Windows 10 contains a slew of additional settings that help you determine how the touchpad works. If the device is responsive but not the way you want, review them and make necessary modifications.
1. Go to Start > Settings > Devices > Touchpad.
2. Scroll down to the Taps, Scroll and zoom, Three-finger gestures, Four-finger gestures sections, and ensure that nothing is amiss.
3. If everything looks okay, but you still keep encountering issues, scroll down to the Reset your touchpad section and select Reset. That helps remove any corrupt configurations. Then, readjust the settings.
4. Restart Laptop or Desktop Device
If you haven’t already, try restarting your laptop or desktop. That usually takes care of any system-related anomalies preventing a built-in or external touchpad from working correctly. Open the Start menu and select Power > Restart to perform a system reboot.
5. Disconnect/Reconnect Touchpad
If the issue occurs with an external touchpad, just remove and plug the USB cable or wireless receiver back in (preferably to a different USB port) and check if the issue recurs. If possible, avoid connecting it to any USB hubs.
If the touchpad relies on Bluetooth for connectivity, you must remove the device from Windows 10 and repair it with your computer.
1. Open the Start menu and go to Settings > Devices > Bluetooth & other devices.
2. Select your touchpad and select Remove device.
3. Select the Add Bluetooth or other device option to pair the touchpad.
6. Check the BIOS/UEFI
You could fix an unresponsive or malfunctioning touchpad by visiting your laptop’s BIOS/UEFI. Locate the touchpad setting and reconfigure it as needed. The procedure differs among laptop models, so you may want to refer to a user manual or online documentation for specific instructions. But here’s a general rundown.
1. Restart your laptop and press the relevant function key to enter the BIOS/UEFI—e.g., F2, F9, F10, or F12.
2. Locate the setting related to the touchpad using the arrow keys. For example, it could be listed as Touchpad or Internal Pointing Device.
3. Make sure that it’s set to Enabled or Advanced. If not, press the Enter button and adjust.
