When my computer lagged hard why did my touchpad stop working??

When your computer experiences significant lag, it can impact various components, including the touchpad. This lag could be due to high CPU usage, insufficient memory, or other resource-intensive tasks running in the background, which can cause the touchpad to become unresponsive. In many cases, the touchpad may stop working temporarily until the system stabilizes or the resource usage decreases.

To troubleshoot this issue, you can try the following steps:

1. Restart your laptop: This can help reset any temporary issues affecting the touchpad.
2. Check for updates: Ensure that your operating system and drivers are up to date, as outdated drivers can cause functionality issues.
3. Close unnecessary applications: If you have multiple applications running, especially resource-heavy ones like video streaming, closing them can free up system resources.
4. Check touchpad settings: Sometimes, touchpad settings can be altered, so ensure that it is enabled in the settings menu.
5. Use an external mouse: If the touchpad remains unresponsive, using an external mouse can help you navigate while you troubleshoot further.

If the problem persists, consider reaching out to your school’s IT support for assistance, especially since it is a school laptop.

Hi kai inthavixay,

Thank you for reaching out to the Microsoft Q&A Forum. I understand how disruptive this feels, let's get this sorted step by step.

1 - Fix Touchpad Issue

Restart by checking if the touchpad is disabled via a function key combination, such as Fn + F7 or Fn + F8 (common on Acer Spin 3 models), as this toggles it on/off. Next, open Device Manager (Windows + X, then select it), expand "Mice and other pointing devices" or "Human Interface Devices," right-click the touchpad entry (like ELAN or Synaptics), and select "Update driver" > "Search automatically" or uninstall and restart to reinstall. If unresponsive during YouTube lag, close browser tabs/apps to free resources, then run the touchpad troubleshooter via Settings > Bluetooth & devices > Touchpad > Reset.

2 - Resolve Windows Update Error

Run the Windows Update troubleshooter first: Settings > System > Troubleshoot > Other troubleshooters > Windows Update > Run. If it fails, open Command Prompt as admin (search "cmd," right-click > Run as administrator) and run these commands one by one: sfc /scannow then DISM /Online /Cleanup-Image /RestoreHealth, followed by a restart.
