I've had a few "red bar" mornings lately - grabbing the Treo on the way out the door only to get one of those "charge the battery immediately" warnings, despite having a well-charged Treo the night before. I've isolated the problem to the screen being locked on all night, caused, I believe, by an alert turning on the screen, which then does not sut off for some reason. I have keyguard turned on (the Palm app, not a 3rd party app), and the "Keyguard: Press Center button to unlock" message is still lit with the screen on all night.

Anyone know how to solve this problem? Thanks in advance.

(I started to search the forum but 'm not sure exactly how to define this problem so I didn't have any luck).
