Great computer, very fast speed, but it has one problem.  The line input jacks do not work.  Calling Assurion and Amazon was not helpful at all.  Dell will not help at all.  They said the computer was used and I would need to do an ownership transfer on their website.  Their website asks for the Federal Office, Department, and phone number, where it was purchased from.No one can supply this information, so their is no support from Dell if you purchase this computer.You're on your own.
