Hardware Environment: HP/Compaq nx7010
When S5 is supposed to be entered the machine reboots instead. This _only_
happens when AC power is connected. When running on batteries the machine shuts
The bug appeared in acpi patch 20040715 and is still present (vanilla 2.6.9).
Traces shows that the kernel still writes the correct values to enter S5. The
bug must be during the setup of the state change.
Steps to reproduce:
Shut down machine with AC connected.
They seem to cover different kernel versions so it might not be the same bug.
bug 2252 went away with Linux-2.6.9 but it didn't go away here, so this system
must be different from that one.
Please try out the patch in bug 2109

please try this debug patch.
it undoes the "poweroff regression" fix in ACPICA 20040427
Patch had no effect.
I am seeing this bug too with 2.6.9.
I recently removed my laptop battery because it is broken, and am running on AC
all the time now. Could this be a reason maybe?
It makes no difference if the battery is connected or not here.
please test the patch in bug 3669
Patch solves problem.
Great work! =)
The patch in bug 3669 solves it, right? I'll mark this one as a duplicate.
