Don't know why but our Revue's fan is now constantly running as long as it's plugged in. I took it apart and blew away all the dust in it. The fan seems to turn without hitting anything, but the sound of the fan running all the time is annoying. Do you think maybe it's a firmware problem? Seems to me that it's not getting the message that the unit is cooled down enough to stop the fan and it continues to run.

This video might help in replacing the keyboard part. https://www.youtube.com/watch?v=OCmPqsvV...
