The
 touchpad is an age-old feature, having long since replaced the 
“pointing stick” (or what I liked to call the “nipple”) as the 
standardized alternative to mouse control on a laptop. But if your 
touchpad stops working while you’re on the move, or in any other 
situation when you don’t have a spare mouse handy, you can end up 
stranded.
But don’t start training yourself to use Windows with 
only a keyboard just yet. Here’s our collection of tips on how to fix a 
malfunctioning touchpad (starting with the simplest).
Note:
 you’ll need an external mouse or touchscreen to go through with some of
 these tips. Also, the following fixes are for laptops running Windows 
OS.
 
1. Touchpad Disable Zone
Unbeknownst to many laptop 
users, there may be a small square logo at the top left corner of your 
laptop touchpad. If you have this logo, then double-tapping it enables 
and disables your touchpad, so there’s a chance that you disabled it 
accidentally.
Try double-tapping that logo to see if your touchpad comes back to life.

If
 you find yourself disabling your touchpad accidentally this way, you 
can disable this feature by going to “Settings -> Devices -> 
Touchpad -> Additional settings -> Touchpad Entry -> Settings 
-> Touchpad Disable Zone -> Untick ‘Double Tap to Disable 
Touchpad'”.
2. Is the Trackpad Disabled in the BIOS?
There’s
 a chance that, for reasons unknown, your laptop touchpad is disabled in
 the motherboard BIOS of your laptop (this could happen after a firmware
 update, for example).
To check if this is the case, enter the BIOS by repeatedly pressing the 
Delete or 
F2 key as your PC is booting. (The button you need to press may vary).

Likewise,
 the BIOS for different motherboards has a different layout, but your 
goal is to find an option called “Internal Pointing Device” or similar, 
then make sure it’s set enabled. This may be under the “Advanced” 
heading if you have one. Once you’ve done this, select the option to 
“Save Changes and Exit.”
3. Re-Enable Your Touchpad Using the “Fn” Key
This
 happened to me several years ago. Perhaps while trying to use a “Fn” 
key to change the volume on my laptop, I disabled my touchpad by 
pressing the wrong button. For weeks I didn’t know what the issue was, 
which wasn’t helped by the touchpad function icon on my keyboard looking
 
just like a monitor icon, and it took me a while to realise that maybe it was in fact a touchpad icon.
While
 holding the “Fn” key, press every function button (the “F” keys) with a
 symbol on it that looks like it could be your touchpad to see if it 
switches back on. (Bear in mind, you might turn off your screen this 
way, so just press that button again if that happens.)
4. Remove Other Mouse Drivers

Have
 you plugged a whole bunch of mice into your laptop in the past and 
never removed their drivers? If so, there’s a chance that their drivers 
are interfering with your touchpad. (Some mouse drivers even disable 
your touchpad automatically!) Go to Device Manager, click the arrow next
 to “Mice and other pointing devices,” then right-click and uninstall 
mice one by one until your touchpad starts working again.
5. Update or Roll Back Touchpad Driver
While
 you’re in Device Manager, right-click your touchpad in the list (It may
 be called Dell TouchPad, Lenovo TouchPad, Synaptics, or similar, 
depending on the brand of your PC.), and make sure that it’s definitely 
enabled. If it is, click “Update driver” to see if there are any updates
 for it that might help.

Finally,
 a lot of people reported that their touchpads stopped working properly 
after getting Windows 10, which means that the W10 driver for your 
touchpad may be misbehaving. In Device Manager right-click your 
touchpad, then click “Properties” and “Roll Back Driver” to see if a 
previous version of the driver fixes the problem.
6. Enable Your Touchpad in “Mouse Properties”
In
 a lot of cases Device Manager doesn’t handle the enabling and disabling
 of your touchpad. If your touchpad somehow got disabled, then to switch
 it back on you’ll need to go to your Windows mouse properties to 
re-enable it.
Type 
mouse into the Windows Search bar 
and go to Mouse Settings. Here, click “Additional mouse options,” then 
in the new window go to “Device Settings,” “Touchpad,” or whatever tab 
is at the far right of the window.

Find your touchpad in the list, select it, then click “Enable.”
7. Disable Tablet PC Input Service
If
 your Windows 10 laptop is a hybrid and has a touchscreen, then there’s a
 possibility that the Tablet PC Input Service, which controls stylus 
functionality, is interfering with your touchpad. If you don’t really 
use the stylus anyway, then it won’t be a big loss to disable it. If you
 do use it, however, you have to decide whether you want to go through 
the inconvenience of toggling this service on and off each time you want
 to use your touchpad.

To disable Tablet Input Service, hit 
Win + 
R, then type 
services.msc
 in the box. In the list of services, scroll down until you find 
“TabletInputService” or “Tablet PC Input Service.” Right-click it, then 
disable it.
Conclusion
Hopefully all your touchpad-fixing 
solutions are right here, but if you can think of any more, then let us 
know. Remember that different laptops may have different software for 
their touchpad, so these instructions may vary slightly, but for the 
most part they should point you in the right direction.
