Lets focus on one issue in this bug report -- the simpler
and more dramatic issue that when you pull out the A/C,
your system shuts down. Lets move the video/X issue
to another bug report, okay? At the end of the day
the two may be related, but buttons & events should
be easier to debug than video.
The log in comment #5 shows that you are receiving a power button event
and the system is executing a graceful shutdown:
Sep 27 13:42:23 tau acpid: received event "button/power PWRF 00000080 00000001"
Sep 27 13:42:23 tau acpid: notifying client 1841[103:1002]
Sep 27 13:42:23 tau acpid: notifying client 2001[0:0]
Sep 27 13:42:23 tau acpid: client has disconnected
Sep 27 13:42:23 tau acpid: executing action "/etc/acpi/default.sh button/power
PWRF 00000080 00000001"
Sep 27 13:42:23 tau init: Switching to runlevel: 0
Lets test your power button...
Please kill acpid and cat /proc/acpi/event
then press the power button, the sleep button, the lid button, and any other
buttons you might have and observe what comes out on the screen.
Then switch between AC and DC a few times and report what you see.
Also,
grep . /sys/firmware/acpi/interrupts/*
between each physical event to see if you can identify which buttons & switches
map to which low-level ACPI events.
Note that you can clear these stats between tests like so:
# echo 0 > /sys/firmware/acpi/interrupts/sci
