Sorry about that. I was trying to reply to a post from about a year ago from a guy named Clark that seemed to have the same problem I have. My Dell Inspiron 1526 fails to boot up about 9 times out of 10. When it fail, the display doesn't do anything and the hard activity light doesn't even blink. On that rare occassion that it does boot up, everything checks out fine. Right now I'm thinking that the battery isn't strong enough to boot it up. When I get a chance, I plan on shutting down, removing the battery, and seeing if it boots up any better on AC only.
