I have a Compaq Presario (laptop) not sure what model number and all of my literature is back in the US where I currently am not for another 2 months, but anyways I went on vacation for a week and when I came back my computer wouldn't turn on. That is to say that the power button would light up and it would make some noise (a fan or something?) but then do nothing. The screen would remain blank and when I went to turn it off it wouldn't turn off unless you cut the power. I tried several different things trying to get it to work (at least ten times) and nothing. I then took it to a store to see if they could help and the second time the store clerk tried it magically turned on. So I took it home and once again got the no-response and then the second time I tried it said it failed to boot correctly and did I want to continue and then said there was a media test failure and did nothing further. On the third try it turned on. Being the second day now that it has worked it did the same thing again, first no response then boot failure then it finally worked.
What does this mean? Is it safe to turn my computer off or will it never turn back on again?
(sorry for the long explanation)
