To turn off the touchscreen on a Chromebook, you need to enable an experimental feature called "Debugging keyboard shortcuts" first. Here are the steps:
- Open the Chrome browser on your Chromebook.
- In the address bar, type
chrome://flagsand press Enter. - In the search box on the Flags page, type "Debugging keyboard shortcuts."
- Find the "Debugging keyboard shortcuts" flag and set it to Enabled from the dropdown menu.
- Click the Restart button that appears to reboot your Chromebook and apply the change.
- After restarting, press Shift + Search + T simultaneously on your keyboard to toggle the touchscreen off or on.
- The Search key usually looks like a magnifying glass or a white dot, depending on your keyboard model.
- When the touchscreen is off, touching the screen will not register any input.
- Pressing the same key combination again will turn the touchscreen back on.
Additionally, you can disable or enable the touchpad with Shift + Search + P if needed
. This method uses an experimental ChromeOS flag, so it might not be available on all Chromebook models or ChromeOS versions, but it is the current standard way to toggle the touchscreen functionality without third-party software or hardware modifications. Restarting after enabling the flag is necessary for the shortcut to work
