Hi @sri78,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

The issue you're experiencing on your HP Chromebook x360 14, where multiple characters or actions are triggered with a single key press, could be due to a few potential causes. Here's how you can troubleshoot and possibly fix the problem.

Restart the Chromebook

• Sometimes a simple restart can fix keyboard glitches. Try restarting your Chromebook by holding down the power button or using the shutdown option from the system tray.

Check for Chrome OS Updates

• An outdated Chrome OS version could cause keyboard issues. Here's how to check for updates:
  1. Click on the time in the bottom-right corner.
  2. Go to Settings > About Chrome OS.
  3. Select Check for updates and install any available updates.
  4. Restart your Chromebook after the update.

Reset Keyboard Settings

• Sometimes customized keyboard settings can cause problems.
  1. Go to Settings > Device > Keyboard.
  2. Check the settings for key functions such as search, tab, and brightness keys.
  3. Reset the keys to their default function if you notice any unusual configurations.

Hard Reset

• Performing a hard reset on your Chromebook can resolve hardware-related issues, including keyboard glitches.
  1. Turn off your Chromebook.
  2. Press and hold the Refresh key and then press the Power button.
  3. Release both keys once the Chromebook restarts.

Test in Guest Mode

• Sometimes user profile-specific issues can cause problems with the keyboard. To check if this is the case:
  1. Log out of your account.
  2. Click on Browse as Guest on the login screen.
  3. Test the keyboard in guest mode. If it works fine, there might be an issue with your account’s settings, and resetting it could help.

Check for Physical Damage or Dust

• Clean the keyboard with compressed air to remove dust or debris that may be affecting the keys.
• Inspect the keyboard for any signs of physical damage.

Powerwash (Factory Reset)

• If none of the above steps work, you can try resetting your Chromebook to factory settings. This will remove all local data, so be sure to back up anything important.
  1. Go to Settings > Advanced > Reset Settings.
  2. Click on Powerwash and follow the on-screen instructions to reset your device.

I hope this helps.

Take care and have a good day.
