I had one issue that occurred on my 9300 when I ran windows update and it took ten minutes (I timed it!) to shut down and then almost 8 to reboot. I ran sys restore and all was well.
My problems have all been with Dell Financial and their "crack" people. Between the English problems, they don't have a clue what to do when you get off their little scripts they have. I called to get an invoice when I didn't get one, and it turned into a missing laptop callback! I went around the world on the phone, when I called the first time. India, Panama, back to India, to Texas, to (I think from the accent) The Phillipines, back to India, and finally back to Tx, where I thought it was all settled. Then, the next day, some guy calls, from India, and says "We have investigated and our records show that your laptop was delivered on June the third, and that someone claiming to be you signed for it!" I snorted and nearly choked on my iced tea. I don't know where they came up with the missing laptop nonsense.
They called again from Dell Financial asking if my laptop had been found. Jeez.
And I thought Acer support was goofy.
