All we're getting is the little green light showing that power is entering the computer. Tried turning it on using just the battery, just the adaptor, and the battery and the adaptor both installed. When we turn on it, we hear nothing....no fan, nothing coming on the screen. Computer seems to be completely dead other than being able to see that power is entering the computer by seeing the little green light. Any idea what this is? Need to at least get the data off of the hard drive (if possible) even if the rest of the computer is shot.
