[arch-general] Weird behaviour A/C vs battery

[Mauro Santos]

I've read that the reboot method/commands sent to the hardware were
being changed to closely mimic what windows does [1], this was meant to
workaround broken bios which don't comply to a standard and are only
made and tested to work with windows.

Maybe somehow that is causing the problem for you, I don't know if there
is any way to use the "old" method but I guess that even if there is
this is worth a bug report in the kernel bugtracker.
