If you are looking for a stylish keyboard with bluetooth connectivity you need to know one dark side of those fancy keyboards.

Bluetooth turns ON once your operation system (windows) is loaded (Bluetooth does not work with DOS). This means you can not use your keyboard before the windows is started. You can not access the BIOS menu using these bluetooth keyboards. This also means you can not have a system password either.

If you have to use BIOS quite a lot OR you have a system with multiple operating systems where you choose which OS to run OR you have to choose/change a booting source,  you can not use a bluetooth keyboard for any of these purposes.
