Hey man, hope you are well!
This is because your laptop has "function keys lock enabled" rather than having the regular F1-F12 functionality!
There's a couple ways to adjust this...
Sometimes on the actual keyboard itself you can enable/disable the Fn lock, or many times laptops have software that allow you to switch between if the Function Keys are F1-F12 Keys or Special Keys.
(Or, you may have to go into your BIOS/UFEI settings and you'd be able to adjust this function key as well).
WITHOUT CHANGING ANYTHING.. you should still be able to use the F1-F12 keys if you hold down the Fn key then press F6 to access the Channel Rack, for example..
But, if you'd like to have your normal operation of F1-F12 instead of the laptop special keys like sleep etc.. then you'll have to do a little research on how to switch the default behavior of the F-Keys on your laptop to normal F1-F12 instead of their special functionality..
