Keyboard error

HP Recommended
HP 19 all-in-one
Microsoft Windows 7 (64-bit)

My father-in-laws HP 19 all-in-one is getting a secure boot violation - invalid signature detected.  I read how to turn off the signature detection in setup.  Unfortunately, when I came to his place to fix it, he is getting a keyboard error before that so I can't use the keyboard to get into setup.  I tried his keyboard in all of the USB ports on the device (6 in total) to no avail, however, the keyboard works fine when I plug it into my laptop.  Any suggestions?

@Mikegee1 Here's a related post that has a solution to your predicament: click here to view,

And if that doesn't help, you may want to perform a hard reset using the below steps and get back to me with the results:

 

Ensure your device is OFF.

Unplug all the external devices (If any).

Disconnect the power from the computer

Press and hold the power button for about 30 seconds.

Connect the power supply

Press the power button to turn on your device and check if the issue persists.
