This is the much-discussed "failure to wake" problem.

My own experience is that this initially occurs after certain kinds of unexpected errors. Thereafter, it will continue to occur until you turn off Auto Adjust Backlight, power down, and power back up. The problem should then be gone (for now), and you can turn Auto Adjust Backlight back on if you wish.

To avoid having to remove the case and back cover so often, I have installed Quaint Reboot from the Windows Marketplace. It contains a "Reboot Now" command that requires no screen interaction. Thus, when this problem occurs, I can reboot simply by activating Voice Command (by holding down the Talk button) and saying, "Start Reboot Now". But after reboot, I must turn off Auto Adjust Backlight or the problem will recur.

Here are just some of the unexpected errors that have triggered this:

1) Installing Microsoft's VOIP package, then attempting to use it immediately without rebooting.

2) Setting the phone to Roaming Only, then attempting to make a call immediately without rebooting.

3) Sending a file to a network printer with Jetcet, then closing the Jetcet program before the file is finished printing.
