Oh, and as an side - if you spend in excess of $1400 on a laptop, you should not be expected to fix it when it is brand new out of the box. In my case/experience, they had me do all kinds of troubleshooting - everything from driver updates to completely re-installing Windows and sending me new drive images - to no avail or success. As it turned out, in *my* case it was just a way to stall me from returning systems within the 21 day period and then they made it incredibly difficult to do exchanges or returns thereafter.
If you are within your 21 day return period and you don't have your problem fully resolved on a laptop that you just spent a small fortune on, return it before they get a chance to deny your returns like they attempted to do with me (forcing me to spend weeks in negotiations and ultimately turn to legal assistance and the BBB).
This post is not here to damage Dell's reputation (they're quite good at that themselves). It is here to help inform and protect consumers like you and me.
