Well, it's finally happened (& this is my 2nd Mini). If the 3rd Mini fails, I don't believe I'll be getting another one & I might also be done with Dell.
My Sony laptop + desktop & Dell 600M, while slow by today's standards + hot like an m f-er, have yet to fail me in ways the Mini has . ~knock on wood~ Oh man, am I'm disappointed....
I'm glad I didn't do any upgrades yet & that this was at the top of the forum.
Edit: I've seriously tested my Mini for about 9 hrs now, & I believe that the OEM AC adapter went bad/shorted out somehow. It is running from the outlet/surge protector currently with a different adapter. The 1st one I used was OEM + the other was non-OEM. I will continue to monitor the computer. I wonder if that's what killed the 1st Mini (because it worked so perfectly that I can't believe it was a lemon or that I have such bad luck)....
I'm glad it seems to be turning out to be a false alarm ('cause I was about to wonder how 2 Minis would fail in the same way in such a short time)....
Edit#2: About the AC adapter/charger that failed, I noticed that it's different to the OEM one that I have now. The picture quality is not exactly what I would like (when you zoom in), but the prongs should be clear enough. The 1 on the left is the one that failed.
