Welcome to HP Support Forums. 🙂

I read that the keyboard locks out on HP computer after every restart or startup. I understand that you have to press the Ctrl+Alt+L keys to unlock it. I'd like to assist you with this case.

I would like to know the following information to assist you better:

• Please let me know the exact computer model no. This link will help you to find the model no: http://hp.care/2bygf7l
• What version of Windows operating system are you using?
• Have you tried to use another keyboard (if available) and checked if that works fine?

Please feel free to reply with the information. I'm always here to help. Cheers! 🙂

hello

Hp notebook Pavilion

operating system - windows 7 64 bit service pack 1, but it was windows 10 before with the same issue.

Tried external usb keyboard after restart it works for a few seconds and then it sems like laptop takes over the other keyboard as well. 

So no another keyboards don't seem to work, and again ctrl+alt+L fix's it 

Thank you

Thank you for replying with the information. 

I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

• Open the device manager.
• Expand "keyboards".
• Right click on the drivers inside keyboards and select uninstall.
• Restart the laptop.

Please run a hardware test on the keyboard if the issue persists:

• Hold the power button for at least five seconds to turn off the computer.

• Turn on the computer and immediately press the F2 key repeatedly, about once every second.

• The HP PC Hardware Diagnostics (UEFI) main menu is displayed.

• Select component tests.

Figure : Example of component Tests options

• Keyboard - Quick interactive functional test of the keys on the keyboard. Click Keyboard, then Run once. The Keyboard Test time is 3 minutes.

I hope this helps. Feel free to keep me posted on the results. Cheers! 🙂
