Current Behavior

When the system is rebooted to UEFI with the Caps Lock LED turned on, the LED status does not reflect the actual state of the Caps Lock key. The Caps Lock LED remains on, but the keyboard input produces lower-case characters. This causes confusion for users who rely on the LED indicator to determine the state of the Caps Lock key.

Expected Behavior

The Caps Lock LED should accurately reflect the state of the Caps Lock key in UEFI.

Steps To Reproduce

1. Turn on the Caps Lock key, ensuring the Caps Lock LED is illuminated.
2. Reboot the system and enter UEFI.
3. Observe that the Caps Lock LED remains on, but the keyboard input produces lower-case characters.
