key F5

[birost]

I connected a USB keyboard to notebook.

But key F5 doesn't work.

Thank you for your help, Mr. mdklassen!

Open a command-line prompt, by holding-down the "Windows" key (bottom-left of your keyboard) and clicking 'R', and then releasing the "Windows" key.

Type:    CMD

Press ENTER

Type:    CLS

Press ENTER

Type:  ECHO ABC

Press ENTER

Press the 'F5' key, and tell us what happens, or tell us if nothing happens.

Try it with both the "internal" keyboard and the "external" USB-connected keyboard.

Press the 'F5' key -> NOTHING if it is a notebook (iinternal keyboard)

>    CMD

Press ENTER

>    CLS

Press ENTER

>  ECHO ABC

Press ENTER

>ABC

Press the 'F5' key -> ECHO ABC, if it is the "external" USB-connected keyboard

So, the 'F5' key on your internal keyboard is not working, while the 'F5' keyboard on the external keyboard works fine.

Is there anything (dirt? hair? cookie chip? bread crumbs?) hidden underneath the "key-cap" ?

Ihave a new notebook, brought it in December 2016.
I tried to use notebook very carefully.

Since it is less than  3 months old, contact HP (via the hyperlink at the bottom-left of this web-page), and exercise your "warranty" to get it repaired or replaced.

Did not find the hyperlink. There is a "Report Inappropriate Content" hyperlink at the bottom-left of web-page.
