Hi Wade, It could be that the gasket, under, the start button shifted. The intermittent, power up & down, has been a Cube problem since they were first introduced. Some people have simply put a bit of paper under the gasket to make it more secure, and others have replaced the gasket. I think there is more info about this at cubeowner.com and at Apple Discussions. kl On Mar 13, 2006, at 4:16 PM, Wade Dunham wrote: > he reports that after a couple > of minutes, it shuts down & restarts intermittently.
