CSO Menu on UEFI Diagnostic

HP Recommended
HP ProBook 450 G2 Notebook PC
Microsoft Windows 10 (64-bit)



I work for a company that uses the HP PC Hardware Diagnostics UEFI on a daily basis for multiple laptops (Versions and primarily). Today I was on the main menu of the diagnostic when I accidently pressed either the escape, tilde (~), or  F1 key - which brought up a CSO number and Agent ID entry field. I simply pressed enter on both fields and was given "CSO Dummy" and "Agent Dummy" on the main UEFI screen. With this - I was given additional options and able to test all USB ports at once which is extremely helpful. 


Problem is, I don't know how to bring up that CSO entry again. Could someone let me know of the key or key combination to bring that up again? I've tried multiple combinations of the keys mentioned above and nothing works.


Thank you,


-Brian W.

Hello Brian,


The key combo is Tab+A.


Hit the key combo on the main screen of the UEFI.


It's as simple as that!


Hope it works for you,
