Power Management Issues
About a week ago I began observing the following behavior in my laptop:
-After placing the latptop on the coffee table and standing up, my kne
brushed the corner causing an ESD
-Since then, when I leave the laptop idle for more than two hours, the
monitor and HDD shut off (as specified in my BIOS settings) but will not
wake again (before I reflashed my BIOS it seemed that this was happening
with a shorter idel period)
-This is what I have tried so far:
-re-flashed the BIOS with latest version from Toshiba
-adjusted the power management settings from the BIOS
-left the computer idle for varying periods of time with basically the
same result (after 2 hours, no wakeup)
-have experimented with leaving the battery in place and also with
removing it after fully charged, leaving the machine to run on AC power
alone (no this did not help)
-tried modyifying the settings in xscreensaver-demo (to no effect)
-tried killing the xscreensaver daemon before I went to sleep (again, no
effect)
-The real kicker: this problem does not occur under Windows XP. I have
already tried leaving the machine running overnight under WinXP (instead of
Debian) and it always wakes up properly, regardless of how long the machine
has bee idle.
-This behavior is also not creating any log files that I am able to find.
Machine Specs:
Toshiba Satellite 2805-S401
PIII-700MHz
256 MB RAM
S3 Savage-IX/MV 8MB video
20 GB HDD
internal floppy and CD-ROM/DVD-ROM
Debian Woody 3.0r1 (stock bf2.4 kernel)
I am at a loss to what the source of the problem could be. I would
appreciate any help.
