Nope, it should have put the machine to sleep mode. After considerable time in sleep mode, the battery may still run out. > while looking at the core99 section of /etc/power/pwrctl > I notice that warning just display a message eitheir via wall etheir via > xmessage, and that's all > > shall I add a /sbin/shutdown -h now line ?? Do you always want to have the machine shut down instead of sleep, even when closing the lid? If so, just add the shutdown command there. If you only want the shutdown on power low, look into /usr/share/doc/pmud for the sample powerfail script, configure pmud to send a signal to init on low battery (man pmud), and set up init to run the powerfail script on power status change (man inittab).
