How to turn off touchscreen on Chromebook with Search + Shift + T
By Alberto Gulotta · Updated · 8 min read
How to turn off touchscreen on Chromebook: Lenovo’s steps, written for its 300e and 500e Chromebooks, are to open chrome://flags/#ash-debug-shortcuts, enable Debugging keyboard shortcuts, restart, then press Search + Shift + T to switch the touchscreen off, and the same keys to switch it back on. The Google Chromebook Help pages read here give no setting for it.
| What | What the pages say |
|---|---|
| The shortcut | Search + Shift + T, once a flag is enabled (Lenovo, HP) |
| The flag | chrome://flags/#ash-debug-shortcuts, Debugging keyboard shortcuts enabled, then a restart (Lenovo, for its 300e and 500e) |
| A setting for it | None on the Google Chromebook Help pages read here; HP says some models have one |
| The touchpad | A setting in Accessibility (Google), or Search + Shift + P, in a note to the same steps (Lenovo) |
| Flags in general | Experimental, may change between updates and may reset during major updates (HP) |
- Open the flag. In Chrome, type chrome://flags/#ash-debug-shortcuts in the address bar, as Lenovo’s steps say.
- Find Debugging keyboard shortcuts. Lenovo says there is a search box at the top of the flags page, and that Disable is selected by default.
- Set it to Enabled. HP says to change the setting from Default to Enabled; Lenovo says to click Enable.
- Restart. Lenovo says to select the Relaunch Now icon to restart Chrome; HP says to restart the Chromebook when prompted.
- Press Search + Shift + T. After signing in again, the same three keys turn the touchscreen off and back on. HP says the change is immediate and that a short notification confirms it.
Turning it back on. Press Search + Shift + T again. HP adds that you can set the flag back to Default on chrome://flags and restart. For a touchscreen that isn’t working, Google’s own steps, which don’t mention the flag, are to wipe off dust or dirt, then reset the Chromebook hardware, then reset it to factory settings, testing after each, and to contact the manufacturer if none of that works; a screen that ignores touches is also in a touch screen that doesn’t respond.
When the touchscreen keeps working
A case on Google’s forum. In March 2023, a Chromebook owner wrote on the Chromebook Community that Search + Shift + T didn’t turn the touchscreen off, and that after enabling the flag and restarting, the flags page showed it disabled again. A volunteer Product Expert asked for the build details, from chrome://os-settings/help and Additional details. The thread is locked; its recommended answer gives the same flag steps, and it records no other fix.
What HP warns about flags. HP’s guide says flags are experimental, may change between updates, may reset during major system updates, and that some versions of ChromeOS may not include this one. Our reading of that warning, not HP’s words: after an update, check whether the flag still says Enabled.
A school or work Chromebook. For education and work devices, HP says to check policy restrictions before enabling Developer Mode, one of the routes below.
Shortcuts that sit nearby. In Google’s list of Chromebook shortcuts, Ctrl + Alt + Z turns ChromeVox, the spoken feedback, on or off; Ctrl + Shift + the Rotate key turns the screen 90 degrees; and Search + L locks the screen. In tablet mode, Google says connecting a mouse switches the Chromebook back to laptop mode, and Power + Volume down takes a screenshot; other screenshot keys are in screenshots on a tablet with a keyboard.
If it is the touchpad you want off
Google’s setting. Select the time at the bottom right, then Settings, Accessibility, Cursor & touchpad, and next to Disable built-in touchpad choose Never, Always, or When a mouse is connected. Google says that if you choose Always and don’t confirm within 30 seconds, the touchpad goes back to the default.
Turning it back on. Google says to press the Shift key five times.
With the flag. In a note to the same steps, Lenovo says Search + Shift + P disables the touchpad.
The other routes HP describes
A setting, on some models. HP says some Chromebooks include a touchscreen control in Settings, and suggests looking under the device and display options and in Accessibility. The Google Help pages read here don’t list one.
Developer Mode. HP also describes terminal commands that need Developer Mode, and warns that turning Developer Mode on wipes the device with a Powerwash, and that turning it off again needs another. This page doesn’t give those steps.
A physical cover. HP mentions a thick, non-conductive screen protector as a temporary answer, and says it may affect screen clarity or brightness, and that some sensitive touchscreens may still register through thin materials.
Which versions. Lenovo’s article was first published on 11 September 2018 and last modified on 13 February 2026; HP’s guide is dated 14 June 2025; the forum thread is from March 2023. None of them names a ChromeOS version, and the Google Help pages give no date; Lenovo’s article lists the 300e and 500e Chromebooks as the systems it applies to. A picture that flickers or breaks up is in a glitching Chromebook screen, and a single faulty pixel in dead pixels.
Where to start
Five ways in.
- “Where do I start?”
- The flag and the shortcut — the flag and the shortcut
- “It still responds.”
- When it does not stay off — when it does not stay off
- “I want it back.”
- Turning it back on — turning it back on
- “It is the touchpad.”
- The touchpad — the touchpad
- “Is there another way?”
- Other routes — other routes
