Classmate pc will not boot.

[S.P.A.M.er 17]

Hi all. Today was the first day since competition that we have tried to use our classmate. We plugged the charger in and tried to turn it on and it won't boot what so ever. There are no beeps, no hardrive activity, and the screen doesn't turn on at all. All that happens is the power light turns on and the num and caps lock blink. We have tried to turn it one without the battery when it was plugged in and now the battery is fully charged. Has anyone had a similar problem and how did you solve it? Thanks for the help. ---Ralph.
