Warranty information on open box/refurb orders from third parties?

HI,

First of all, sorry if this is the wrong area of the forum for this...

I am considering purchasing an open box laptop from a local Microcenter and want to know, what type of warranty does Dell extend to people who have bought an open box from a third party retailer? Microcenter says that the laptop has a 90 day warranty, but I am not sure if that's a warranty they extend or if it's one that Dell extends.

I just want to know what type of warranty I would have from Dell if I purchase that laptop from Microcenter.
