The touchpad provides full mouse functionality to your laptop. But there are instances when the laptop may be more productive without the touchpad.
For instance, if you have attached an external mouse to your laptop, you may not need the built-in touchpad. Sometimes your thumbs or palm may accidently touch the touchpad while you’re typing and this may inadvertently move your mouse cursor to a different location in the document.
If you are not looking at your screen when the pointer jumped, you’ll end up typing in the wrong place. To avoid such situations, it may not be a bad idea to disable the touchpad at least when you are using a mouse or are typing a long document.
How to disable it
Most laptop computers either have a button to easily disable the touch pad or there’s an icon in the system tray that lets you manage the various settings of the touchpad.
If you don’t have that icon, you can go to Control Panel –> Mouse Properties –> Touch Pad to enable or disable the touchpad. Some laptops don’t have dedicated buttons but you can use Function keys (like Fn + F5 on Dell computers), to toggle the state of your touch pad.
Finally, if none of the above solutions work for your brand of laptop, try TouchFreeze — it’s a free Windows utility that will temporarily disable the touchpad of your laptop as you go into typing mode.
The utility runs in the system tray and requires no configuration.
