It looks that Dell did have the spare parts handy and sent the technical service yesterday.
As I suspected, the failed item was the power supply, so the repair took just a few minutes.
In the meantime, I learned in Ubuntu a couple of things that may be of use for someone else.
1. MB3D runs under Wine. I didn't stumbled into any major problem to use it, except the snail speed provided by the old laptop.
2. J-Wildfire also runs very well under Ubuntu.
Thanks again to those of you that cheered me with the problem!

Today my Dell refused to turn on. This is my 4th nasty event with this PC -StudioXPS 910- in less than 3 years. It seems these guys are all buying shares of Apple, going peacefully to bankruptcy.
For those of you living in real countries (I live in Argentina) my PC in under a 3 year guarantee. The response to my request was: if we conclude that we have the potential spare parts needed, the service may come in the next 7 working days but, if some of those parts have to be imported, we commit to have it fixed in the next 48 DAYS!
As a result, you will not be seen me often in dA until this is resolved. I am now in an old laptop running Ubuntu 13.04 (really spectacular), but all my parameters and programs are in the Dell so no new production and regrettable not much of faving and commenting in the meantime.
Cheers and hugs!
