How can I boot my HP Probook 6470b without a keyboard

[Kaylor_11xer]

Hello, I'm having an  issue with this laptop, I'm currently stuck in Hardware Diagnostics UEFI. Everytime I try to boot the laptop it shows me the Blue HP logo as normal but keeps sending me to Hardware Diagnostics UEFI, and sadly my keyboard stopped working making it hard to exit the UEFI. I try  numerous ways to to try exit but always making my return to HD UEFI, I have  no Idea what I can do please help me.

If the keyboard fails to work in the UEFI diagnostics, then there is a hardware problem.

HP releases newer UEFI diagnostics periodically.
When you select F2 during boot you are requesting UEFI diagnostics.
There is an updated diagnostics package Click Here
Look for the phrase 'issues outside the OS',
Expand the'+'symbol and click the DOWNLOAD button.
The version of the UEFI diagnostics is shown at the left of that DOWNLOAD button.
When you press F2 to run diagnostics please ensure the version is the new one.

This UEFI update can be downloaded on any system to a USB flash for later installation.
