Thanks for all your replies. I no longer feel lost and lonely. Good news. My EE miraculously turned on, and I believe it happened after I took the battery out and put it back in without the charger being connected. So far it seems to be working normally. I'll report if it happens again.
I want to clarify that the Entourage Edge recommended support site does not help with hardware problems. If it doesn't turn on, they said, they can't help.
Of course, I first tried calling the EE support line which did not connect me after numerous tries. I've no doubt most of you know this. It would be nice to know what their position is on honoring their one year warranties since I have less than seven months owning it.
However, I would still like to know if there is a reputable service company that can repair Dualbooks for hardware problems.
Thanks again.
