Tiger crash, forced restart; log linked

Question

This may related to my query of a week ago <http://tinyurl.com/yrbwwt>.
After closed & on AC adapter for 8+ hours, opened to blank screen. (No symptoms since last week) No spin-up, no flicker. Tapped on brightness adjustment buttons (& volume). No response. Caps Lock & Num Lock both lit. Pressed battery level indicator button on battery-full charge. AC adapter glows green.
Forced restart Cmd+ Ctrl+ Power. Normal boot. As startup items loaded, a Finder alert appeared. The alert read:
<<--
The computer was restarted after Mac OS
X quit unexpectedly.

Apple.
<<Report...>> <<OK>>

Last week, there was no alert generated. This time, no scary beeping & flashing at boot. I also took pains to video record today's event, once I realized it would not wake.
TIA all. Your comments last week were of value. Perhaps the log contents will mean something to a more technically inclined user.
