I thought I had worked around this problem by turning off Auto Adjust Backlight. But just today, it happened again:

I made a call while roaming. The screen turned off as it usually does when a call starts, but then would not turn back on again.

Here is my latest idea:

I have reinstalled the Quaint Reboot available in Windows Marketplace. This program has two Start Menu entries, Reboot! and Reboot! Now. Reboot Now! requires no screen interaction once invoked. Hence, I can run it from Voice Command.

In short, my solution is not to eliminate the failure-to-wake, but to make reboot much easier.
