You can usually find out what button you need to press on the reboot screen or by checking the manual that came with your laptop. (Other laptops may use a different key to get into BIOS.
To turn it back on, you’ll need to get into your motherboard settings. If your touchpad isn’t working, there is a chance it was disabled through your motherboard. Your touchpad can become disabled through your motherboard BIOS during firmware updates or even because of a virus. Not all laptops have these, but they are becoming more common. If your touchpad has a small logo/icon in the top corner, try double-tapping it to see if your touchpad kicks back on. If you tap this icon, you’ll turn off your touchpad. This can often be found on the top corner of the touchpad-and it’s usually indiciated by a logo/icon. Some touchpads come with a built-in disable button.
If you can’t find those, try going through each Fn key and see if one of them turns your touchpad back on. You can try the F9 key, or look for the Fn key that has a square next to a square with a line through it. (A lot of laptops use the F9 key, though.) Of course, this variation varies from computer to computer, so we can’t tell you precisely what buttons to push. If this is the case for your computer, it is possible you accidentally disabled your touchpad by pressing this combination on your computer. Some laptops have an Fn key function that disables the touchpad.
