Inspiron 5400 touchpad issue

Check the touchpad settings

If your Dell doesn't have a touchpad function key, you can access the setting directly. Here's how:

1. Type “touchpad settings" in the search bar on the bottom left of the screen.
2. Make sure the touchpad is turned on. For extra peace of mind, check the Touchpad sensitivity setting. If it's set too low, that may be your issue.

In case you changed some of these settings, you can change them back by scrolling to the bottom of the touchpad settings and resetting them.

Check the touchpad settings in BIOS

The Basic Input/Output System (BIOS) is the software responsible for booting up your laptop. But sometimes it malfunctions during updates or due to viruses, and that may be the reason your mousepad isn't working.

To turn it back on, follow these steps:

1. In the search bar on the bottom-left of the screen, type "advanced startup" and click Change advanced startup options.
2. Under Advanced Startup, select Restart Now.
3. Find the Internal Pointing Devicesetting. You can find it in your advanced settings. Make sure it's turned on.
