I think they offer tech support for the brands they sell there aka Macs and Fujitsu, etc (maybe Lenovo, I'm not sure). They'll always look at your computer if you'd like them to, but it costs $15 and if there's a part that needs to be replaced, they can't do it for you if they don't house that brand (that's how it was an year or so ago).
Source: me. My Dell decided to stop charging.
Edit: It might have changed since then though because the tech support area seems to have been revamped. Easiest to just go and ask! The staff's pretty helpful.
TL;DR--YES THEY DO
