Welcome to our HP Community forum!

To fix a frozen keyboard on the BitLocker recovery screen without buying an external keyboard, you can use the On-Screen Touch Keyboard or bypass the pre-boot environment by toggling the UEFI/BIOS settin...

This issue likely happened because the BitLocker recovery screen loads basic hardware drivers before Windows completely starts up. A glitch in the system's pre-boot environment can temporarily cause it to fail to recognize the internal keyboard connection.

Step-by-Step Fixes:

1. Activate the On-Screen Keyboard (Easiest Fix):

If your laptop features a touchscreen, or if your built-in touchpad is still registering movement, you can bypass the physical hardware keys entirely.

• Look at the bottom-right or bottom-left corner of the blue BitLocker screen.
• Tap or click the Ease of Access / Accessibility icon (which looks like a clock or a stick figure).
• Select On-Screen Keyboard or Touch Keyboard.
• Use your finger or the touchpad to tap in your 48-digit recovery key.

2. Perform a Hard Hardware Reset:

Forcing the motherboard to fully drain its power resets the internal keyboard controller chip, forcing it to look for the keyboard on the next startup.

• Press and hold down the physical Power button on your laptop for a full 30 seconds until the machine shuts off completely.
• Unplug any power cables, mouse dongles, or USB drives from the sides of the laptop.
• Wait 1 minute, plug the power cable back in, and turn it on. Check if the keys respond.

3. Toggle "Fast Boot" in the BIOS Menu:

If "Fast Boot" is enabled, the laptop skips loading initial USB and input drivers to save time, which frequently locks out the keyboard on the BitLocker screen.

• Turn the laptop completely off.
• Turn it back on and immediately tap the Esc key repeatedly until a Startup Menu appears. (If Esc fails, restart and tap F10).
• If your keyboard works in this menu, your hardware is perfectly fine, and the issue is strictly a BitLocker bug.
• Select BIOS Setup (or press F10).
• Navigate to the Boot Options or Advanced tab using the arrow keys.
• Look for Fast Boot and switch it to Disabled.
• Look for USB Legacy Support and make sure it is Enabled.
• Press F10 to Save and Exit. The laptop will restart back to the BitLocker screen, and your keyboard should now type normally.

4. Drop to the Recovery Command Prompt:

If you cannot type on the main blue screen, you can use Windows' fallback environment to input the key via a text command.

• On the BitLocker screen, look at the bottom options and press Esc for more recovery options (or click Skip this drive).
• Navigate to Troubleshoot > Advanced Options > Command Prompt.
• If the keyboard works inside this black command box, type the following command to unlock your hard drive manually (replace the X's with your actual 48-digit recovery key):
  manage-bde -unlock c: -rp XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX-XXXXXX
• Press Enter. Once it states it is successfully unlocked, type exit, press Enter, and click Continue to Windows.

Keep in mind that the BitLocker recovery screen only accepts numbers (0-9) and the function keys (F1-F10). It will not allow you to type letters, as letters are never included in an official 48-digit Microsoft recovery key. If you were trying to type letters, the keyboard might actually be working but blocking the invalid inputs.
