Hi, I purchased a mini 9 in November. It has been really nothing but trouble from day one. It would lock up or freeze randomly. Finally, it just quit around Christmas, and after a couple of hours on the phone, it was returned to depot for service. The motherboard was changed and the unit returned. It locked up during boot. I changed anti virus and messed with every suggested setting without much success. It would run sometimes for hours and then lock up. Or sometimes it would take 3 or 4 tries just to get through boot-up. Last evening, the unit died again. Blank. No LED, no power, nothing. I spend a couple of hours on the phone with Dell and they are taking back to depot for service. I'd really like another unit as this one has issues.
I'm looking for suggestions (other than using it as a door stop).
