Hi - starting a couple of days ago, my Dell Mini 9 (bought in December 2008) would not turn on. I hit the power button, the power light turns on white for about 10 seconds, and then turns off. Screen stays blank and dark. I've tried getting a new AC adaptor, and powering on with and without the battery, but it's always the same - the power light coming on for ten seconds or so, and then going out, but no other activity. Any ideas as to what's going on, or what I can do? Not sure if matters, but a couple of weeks ago I clean installed Ubuntu desktop 10.04 LTR. Thanks in advance for your help.
