Jaunty: computer does not hibernate/suspend after critically low batter

[Tihomir Plachkov]

Hi Xandros,

Thanks for your answer. Looks promising. I will give it a try, although I
have to spend a whole day around my 9 cell batter to charge it and discharge
it 3 times. I'll give it some heavy discharge boost with some gaming
then....  :).
 By the way in DMESG I receive messages from ACPI but when running the
command acpi -b the shell tels me it is not being installed. Do I need to
install only the command acpi or it is a part of some tools-kit I am
missing. Yeah silly question but I do not know the answer :).
And does acpi -b give the same output as

cat /proc/acpi/battery/BAT0/state

sudo Greetings,

Tish
