You can re-enable an existing Chromebook touchscreen with Search + Shift + T when debugging keyboard shortcuts are enabled, but software cannot make a non-touch built-in display touch-sensitive. A functioning touchscreen normally works automatically, so confirm your exact model’s hardware and test touch before changing anything.
The short version
- Check the configuration: Confirm touchscreen support in the manufacturer’s specifications for your exact model.
- Test touch first: Tap a control, scroll with your finger, and try a two-finger zoom.
- Restore disabled touch: When debugging shortcuts are enabled, Search + Shift + T toggles the touchscreen.
- Add an external touchscreen: A compatible touch monitor provides touch input on that monitor without changing the built-in screen.

Confirm your exact model has a touchscreen
Find your Chromebook’s model on its manufacturer’s official website and check the display specifications. Match the exact configuration, because models within the same product family can have different screens. A family name alone does not confirm touchscreen support.
For an ASUS Chromebook, select Search on the ASUS website, enter the model, and open its product page. Select Tech Specs, then examine Display for touchscreen support. If your configuration has a non-touch display, consider a compatible external touchscreen.
Test touch and check Diagnostics
Tap an onscreen control, then touch and hold an item to test right-click behavior. Drag a finger to scroll, and pinch or spread two fingers to test zoom. When these gestures work, your touchscreen is already active.
On current ChromeOS builds, open Settings > About ChromeOS > Diagnostics, or search for Diagnostics in the Launcher. Select Input and look under Touchscreen for Built-in touchscreen or your connected touchscreen. Select Test, then Get started, and tap and swipe across the test area with up to five fingers.
A missing touchscreen entry means Diagnostics has not detected one. It does not conclusively establish that your model lacks touch hardware, so compare that result with the manufacturer’s specifications. Older or managed builds may differ.
Re-enable touch with the debugging shortcut
If touch was turned off through the debugging shortcut, the same shortcut can restore it. Acer documents this method for touchscreen Chromebooks where the experimental flag is available and permitted, and Developer Mode is not required. In Chrome’s address bar, enter the following address and press Enter.
chrome://flags/#ash-debug-shortcutsSet Debugging keyboard shortcuts to Enabled, then select Restart. After the Chromebook restarts, press Search + Shift + T together and test the screen. On a keyboard with a Launcher key, use Launcher + Shift + T.
This shortcut is a toggle, so pressing it again disables touch. Once touch responds, stop toggling it. The similar Search + Shift + P shortcut controls the touchpad, not the touchscreen. If your school or workplace blocks the flag page, contact your administrator.
Add and calibrate an external touchscreen
A compatible external touchscreen can add touch input even when your Chromebook’s built-in display is non-touch. Choose a monitor whose manufacturer explicitly supports ChromeOS touch input, and check compatibility with your Chromebook’s display and USB connections. Touch works on the external monitor while the built-in display remains unchanged.
ViewSonic advertises touch compatibility with Windows, Android, and Chrome for the TD2455, but its specifications list Chromebox rather than Chromebook, so confirm support for your Chromebook with ViewSonic before buying. For that model, use a compatible USB-C connection carrying both video and USB data. With a separate video connection, also connect the monitor’s USB upstream connection as required by its instructions.
If touch is misaligned on a detected, compatible external touchscreen, select the time and open Settings > Device > Display. Select the external touchscreen, choose Calibrate touchscreen, and select the circles marked Tap here. The display settings label may read Displays; press Esc to exit calibration if necessary.
Calibration corrects where touches land on an external touchscreen. These steps apply to external displays, not the Chromebook’s internal panel, and cannot add touch sensing to an ordinary display.
Set up tablet mode and touch typing
On a Chromebook designed to work as a convertible tablet, fold the screen over its hinge to activate the tablet interface and on-screen keyboard automatically. Disconnect a connected mouse if it is keeping the device in laptop mode. Ordinary touchscreen use also works in laptop mode, so folding the screen is not an activation requirement.
To enable the software keyboard separately, select the time, open Settings > Accessibility, and find Keyboard and text input. Turn on On-screen keyboard. This enables a typing tool that you can also operate with a mouse; it does not turn on the screen’s touch sensor.
Restore a touchscreen that stopped responding
Turn off the Chromebook and clean the screen gently with a soft, clean cloth slightly dampened with water or screen cleaner. Apply liquid to the cloth rather than directly to the display, and let the screen dry before turning the Chromebook on. Temporarily remove an added screen protector or privacy filter, then test again.
A restart can clear a temporary system error. Turn the Chromebook off and back on; ASUS specifies holding Power until shutdown before powering on again. If the whole computer has stopped responding, review the steps to restart an unresponsive computer before testing touch.
Next, connect to Wi-Fi and select the time, then open Settings > About ChromeOS > Check for updates. Allow an available update to download and select Restart when prompted. If an update has already downloaded, you can also select Restart in the Update device notification. Updates can repair software faults on Chromebooks still receiving them; managed devices may require administrator assistance.
Fix page and account interaction problems
When system controls respond but one browser tab freezes, press Ctrl + Shift + R to hard-refresh that page. Retest the page after it reloads. This addresses a tab failure rather than a touchscreen disabled across the system.
To compare behavior outside your normal account, select the time, open Power, and select Sign out. At the sign-in screen, select Browse as Guest, then test system controls and a webpage. Follow the steps to browse as a Chromebook guest if needed; school or work administrators can disable guest browsing.
If touch works in the Guest session, that suggests the problem may involve your normal profile. Treat the comparison as a clue rather than a repair, then check extensions or apps associated with the failure.
For a suspected extension, open Chrome’s More menu, then Extensions > Manage extensions. Turn extensions off individually and retest after each change. Once you identify an interfering extension, select Remove and confirm with Remove.
If an app causes freezing or interaction problems, open the Launcher and right-click the app. Select Uninstall or Remove from Chrome, as offered. Select Uninstall to confirm, then retest.
Reset hardware and settings if simpler fixes fail
Back up important files in Downloads before a hardware reset, because it might remove some of them. For most Chromebook laptops, turn the device off, hold Refresh, and tap Power. Release Refresh when startup begins; follow the manufacturer’s model-specific instructions when the standard combination does not apply. Google also documents holding Back + Refresh + Power for at least ten seconds as an alternative.
Chromebook tablets use a separate procedure. Hold Volume Up + Power for at least ten seconds, then release both buttons. Test touch again after startup.
For a settings or extension problem, try Safety reset where it is available and permitted. Select the time, open Settings > System preferences, then under Reset, select Safety reset. If the confirmation dialog appears, uncheck Help make ChromeOS better by reporting the current settings if you want to opt out of reporting, then select Safety reset. After completion, select Done.
Safety reset preserves local files and apps while restoring settings and disabling extensions, but it is not a guaranteed touchscreen repair. Consider a factory reset only after less invasive steps fail, and back up local files first. Powerwash erases local accounts, apps, settings, and files, so review how to factory reset a laptop safely before proceeding. For a school or work Chromebook, contact your administrator.
On a personal Chromebook, sign out and hold Ctrl + Alt + Shift + R. Select Restart, then select Powerwash > Continue. Complete setup and test touch again.
Alternatively, on current personal Chromebooks where Powerwash is allowed, open Settings > System preferences. Under Reset, find Powerwash and select Reset. If the eSIM warning appears, select I understand that installed eSIM profiles will not be removed by Powerwash, then select Continue. Select Restart, and after restarting, select Powerwash followed by Continue.
Reinstall ChromeOS or arrange repair
If touch still fails after cleaning, a hardware reset, and a factory reset, contact your Chromebook manufacturer for diagnosis or repair. Provide the exact model and explain whether touch previously worked. ChromeOS recovery is another later troubleshooting option that reinstalls the operating system and erases local storage, so back up files first. On a managed device, ask your administrator for assistance.
To enter recovery, disconnect peripherals, hold Esc + Refresh, and press Power; release the keys when recovery appears. Some models use Esc + Maximize + Power instead. On Chromebook tablets, hold Volume Up + Volume Down + Power for at least ten seconds. If your Chromebook offers internet recovery, select Recover using internet connection and follow the displayed instructions.
For USB recovery on a Chromebook with an available recovery image, open Google’s Device Recovery Utility on a working M55+ Chromebook, or on a Windows or Mac computer with Chrome installed. Google’s recovery instructions also refer to it as Chromebook Recovery Utility. Select Get started, enter the affected Chromebook’s model or select Select a model from a list, then select Continue.
Choose a USB drive of at least 8 GB, select Continue, then select Create now; creating recovery media erases that USB drive. Enter recovery mode on the affected Chromebook using the appropriate button combination above. Select Recover using external disk and follow the instructions, remembering that recovery also erases the Chromebook’s local storage.
Frequently Asked Questions
Why does tapping select an item without opening it?
ChromeVox changes touchscreen gestures, so tap twice to activate the focused item when the screen reader is enabled. If you enabled it accidentally, press Ctrl + Alt + Z to turn it off and restore ordinary touch interaction. On Chromebook tablets, you can also hold Volume down + Volume up for five seconds to toggle ChromeVox.
How can you run an additional touchscreen test on an HP Chromebook?
On supported HP touchscreen Chromebooks with HP Support Assistant for ChromeOS and ChromeOS 99.0.4844.57 or later, connect the AC adapter and open HP Support Assistant. Select Check your touch screen, then Run touch screen check, and tap each rectangle to reveal the image. HP designs the test to finish within three minutes. If it fails, select Launch Virtual Assistant or contact HP Support.
What should you do when touching one external screen affects another?
On current ChromeOS configurations with at least two external displays and an external touchscreen, open Settings > Device > Displays and select Map your touchscreen. Tap the displayed targets on the corresponding touchscreen, and press Esc to skip a screen that is not touch-capable. ChromeOS hides this option when those hardware conditions are not met.
How can an administrator allow access to the touchscreen flag?
If you are an authorized administrator, open Admin console > Devices > Chrome > Settings, then open User & browser settings and select the relevant organizational unit. Open Content > URL Blocking, add the necessary exception under Blocked URL exceptions, and select Save. This restores access to the flag page; it does not itself enable touch.
Why might a managed Chromebook lack a touch keyboard?
Your administrator can control keyboard availability through the Accessibility on-screen keyboard and Touch on-screen keyboard policies. Ask them to review those policies, including Enable touch on-screen keyboard in tablet mode and Enable touch on-screen keyboard in both tablet and laptop modes. These policies control the software keyboard, not touchscreen hardware.
Does Powerwash remove installed eSIM profiles?
Installed eSIM profiles are retained during Powerwash on Chromebooks where they apply. The factory reset still erases local accounts, apps, settings, and files, so retaining an eSIM does not replace a file backup.
