On my Lenovo laptop, there's a BIOS setting to swap them, which I was very happy to find!
I'll see if I can find that setting on my laptop as well :) thanks
Lenovo introduced the BIOS setting in late 2009. If you have an older system there may be an updated BIOS. Here is a video showing how to do it https://www.youtube.com/watch?v=uR955qVc068
