Err, wrt cussing I think you've skipped reading the Community Guidelines
(link at the top).
Some Toshibas have an anti-feature where the BIOS locks you to a specific
WiFi card, so he might need USB WiFi for which there are some FSF Respects
Your Freedom devices available from two suppliers see:

Booting a USB stick with Trisquel on it is the best way of checking any PC
you might buy for use with any recent distro. If money hasn't changed hands
yet that would be advisable in this case, just cos it's locked doesn't
necessarily mean the WiFi won't work.
Thinkpenguin do laptops which are guaranteed to work with Trisquel and Mint
(link low down in panel on right of this site). But you have to pay import
duties on top - so watch it.
Finally, yes agreed, there's no need for anything other than just a freedom
respecting distro on a PC.
