The Problem

It is a strange situation: plug in a USB mouse and it works perfectly, yet the laptop’s built-in touchpad does nothing. Users who travel or work in tight spaces find this especially inconvenient. The fact that an external mouse functions is actually a helpful clue, since it points away from a deeper system fault. In most cases TIARA4D Login the touchpad has simply been switched off or needs a quick driver refresh.

Possible Causes

• The touchpad was disabled by a function key or in settings.
• A driver issue that stopped the touchpad from responding.
• A setting that turns off the touchpad automatically when a mouse is connected.
• A frozen input service that a restart can clear.

First Troubleshooting Steps

1. Look for a touchpad function key, often near the top row, and press it with the Fn key to re-enable the pad.
2. Open the mouse and touchpad settings and confirm the touchpad toggle is switched on.
3. Check whether a setting disables the touchpad when an external mouse is plugged in, and turn it off. This option is enabled by default on many laptops and explains why the pad seems dead only when a mouse is attached.
4. Restart the laptop to reload the input services that control the touchpad. A restart frequently brings a frozen touchpad back to life by reloading the drivers that manage pointer input.

Advanced Steps

1. Reinstall or update the touchpad driver through Device Manager or the maker’s support page.
2. Run the hardware troubleshooter to let Windows detect a disabled or faulty pointing device.
3. Roll back the touchpad driver if the problem appeared right after a recent update.
4. Test the touchpad in safe mode to see whether another program is interfering with it. If the touchpad works in safe mode, a third-party app installed recently is likely the cause of the conflict.

Safety and Data Warning

Stick to official driver sources when reinstalling, and keep the external mouse handy so the laptop stays usable throughout troubleshooting. Avoid making sweeping system changes for a problem this isolated, since the cause is almost always a simple setting or driver.

Conclusion

A dead touchpad alongside a working mouse usually means the pad was disabled or its driver stumbled, not that the laptop is failing. Checking the function key and settings fixes many cases instantly, and a driver refresh handles the rest. Because the issue is so contained, the gentle steps above are almost always enough to restore normal use. If none of them work, a quick visit to a repair shop can confirm whether the touchpad hardware needs replacing.
