Most modern laptops come with a touchpad mouse built into the computer. If you've tried to use the touchpad and the mouse pointer on screen is unresponsive, chances are that you or someone else has accidentally disabled the touchpad using one of the Function keys on the computer. To fix an unresponsive touchpad on your laptop, reactivate it using the Function key on the keyboard. This process is different for each computer manufacturer.
Locate the "Fn" key in the lower right or left corner of the laptop keyboard. The "Fn" key typically has different coloured text on it or the key itself is a different colour.
Locate the function (F1 through F12) key at the top of the keyboard that disables or enables the touchpad on the laptop. The key typically has an icon that resembles a touchpad with a finger touching it or a touchpad with a diagonal line through it.
Press both the "Fn" and touchpad Function key simultaneously to reactive the touchpad on your laptop. Move your finger along the touchpad to verify that it works. Press the combination at any time to disable the touchpad again.
- Some computers have a coloured light in the upper left or right corner of the touchpad. Double-tap the light on the touchpad with your finger to re-enable the touchpad.
- If you are unsure which function key enables and disables the touchpad, try each and attempt to use the touchpad after each.
- Mac computers use "F2" to disable and enable the touchpad.
- Acer computers use "F7" to disable and enable the touchpad.
- Toshiba computers use "F9" to disable and enable the touchpad.
- Asus computers use "F3" or "F7" to disable and enable the touchpad.
- Dell computers use "F7" to disable and enable the touchpad.
