G5 power on using keyboard

Hi all.

I have a laptop Dell G5 80% connected to an external monitor, keyboard and mouse.

How to power on the laptop from the keyboard. Usually, there is an option in the BIOS that allows it, no only from the keyboard, but from the mouse as well.

How to do it on this laptop? Is it possible?

BTW. Why when I try to post a message in the forum, there is not an option in the "Select Location" combo for Gaming G serie laptops?

Regards.
