System recovery unable to detect keyboard

4.5

You reach the recovery menu but cannot type or navigate because the keyboard is unresponsive.

Symptoms
  • Keys don't work
  • Cannot select language
  • NumLock light off
Possible Causes
  • Missing USB drivers
  • Legacy USB disabled in BIOS
  • Wireless keyboard sync

Step-by-Step Fix

1

Use Wired Keyboard

Plug in a basic USB wired keyboard; wireless ones often don't work in recovery.

2

Enable Legacy USB

Enter BIOS and ensure "Legacy USB Support" is Enabled.

3

Try Different Port

Move the keyboard to a USB 2.0 port (usually black, not blue).

When to See a Technician

Some modern laptops require specific "Intel VMD" drivers to see any input devices in recovery.
