Problem

Function Keys F1 -F12 are not working in MicroStation the laptops media functions are activated instead.

Solution

The issue is most likely caused by the laptop and not MicroStation.

Check the laptops Keyboard and Mouse Driver to see if the Function Keys can be set to legacy behaviour.
On some laptops you might have to download a specific keyboard driver to acheive the above. 

Yet other laptops you might have to adjust the Function Key settings on BIOS level.
If this is the case then please consult with your laptop manufactures support department.
