Laptop Keyboard not working on cold start up. I must restart to enter pin.

Question

After a power down and turn on, my keypad does not allow me to enter my pin (keyboard doesn't function). Only after I go to "restart" does the keyboard function.

Operating on a Lenovo 20KJ002JUS Microsoft Windows 11

Answer 1

1

Open Command Prompt, then paste in this command and press Enter:

msdt.exe -id KeyboardDiagnostic

Run that Keyboard Troubleshooter to see if that can solve the problem.

2

If that does not resolve this for you

Open Device Manager

Expand the Keyboards section

Right click your keyboard and choose 'Uninstall'

Then restart your PC

3

If the problem is still not resolved, open the Settings App.

Go to Windows Update - Update History.

What is the KB number of the latest update that was installed, is it the optional KB5089573 June preview update?

Answer 2

This behavior matches a known Windows 11 bug introduced by a recent update where the keyboard does not work on initial (cold) startup but works after a restart.

A commonly effective workaround is to disable Fast Startup so the system performs a full, normal boot instead of a hybrid one:

1. Open Control Panel.
2. Go to Hardware and Sound > Power Options.
3. Select Choose what the power buttons do.
4. Click Change settings that are currently unavailable.
5. Under Shutdown settings, clear the checkbox for Turn on fast startup (recommended).
6. Click Save changes.
7. Shut down the laptop completely, then power it on and test the keyboard at the PIN screen.

If the issue started immediately after a Windows update and disabling Fast Startup does not help, check Windows Update for any newer fixes that may address this startup keyboard issue.
