If you're having issues with a touchscreen, for instance random 'ghost clicks' or other annoyances, you can try turning it off with these steps:

1. Open up a new tab in Chrome using the + symbol at the top
2. Type or click chrome://flags/#ash-debug-shortcuts
3. This should open a window with an option for "Debugging keyboard shortcuts"; click Disabled and change it to Enabled
4. Make sure you're not in the middle of something, then click Restart in the lower right of that window
5. When the system is back on, press Shift + Search (the magnifying glass) + T and check the touchscreen is off

From this point on, pressing Shift + Search + T will toggle the touchscreen on that Chromebook. If you need to do this, please contact us using the information below for a replacement.
