How do I update a page if F5 does not work?

I bought a new LapTop some time ago. In this model you can on the F5 button "silent" set (F6 is quieter, F7 louder), but not one page refresh. That's annoying pretty much and if I google, there's always something of the F5 button to update.

(have a Windows 10 Probook)

Then it will be FN + F5.

Can I change in the BIOS.

Should also refresh in the browser with such a repeat button.

Must be a strange laptop, because the other functions of the F-keys are triggered only when pressing the Fn key simultaneously.

So check if the Fn key is locked or defective

Otherwise, you can use any browser also by clicking on the "Refresh icon" in the menu bar update

At the bottom left is an FN key that you must hold down and then press F5. If you do not press the FN key, the multimedia functions of the key are used like "Pause, Volume Down and Volume up".

Otherwise there's still

CTRL + R
Right mouse and "reload"
Icon at the top of the bar at your browser. Is usually a down arrow
