Hi,
I want my laptop to shutdown when the battery is critical low, but the
ACPI Battery info warning only comes on at a battery level of 10, but I
just noticed that the kernel logs:
kernel: battery0: critically low charge!
..this happens at battery "life" 7. Better point of shutting down, this
will give me at least 10 minutes more ;-)
How can I catch this in the devd.conf?
My current catch of the battery notifications looks like this (and it
works nicely, but in my point of view, too early):
notify 10 {
match "system" "ACPI";
match "subsystem" "CMBAT";
action "/usr/local/etc/rc.d/battery";
};
Of course, I could make a loop in the "battery" shell script to catch it
from the "sysctl -n hw.acpi.battery.life" ;-), but if I can get the
kernel "critically low charge", I think that's better.
Info: Laptop, Toshiba Satellite Pro L40
