I recently encountered a problem with kahelOS in my laptop. I was using the battery power and even though the battery is not yet totally empty, the power went off without giving any warning. Do I need to change any of my settings?

Kahel by default will use the 'performance' power management
settings, here's the necessary steps to solve this problem.1. Right-click the panel and choose 'Add to Panel...' then add the 'CPU
Frequency Scaling Monitor'. Depending on your CPU, if your using
multiple-cores, you might want to add 2 applets.2. Right-click the applet, then choose Preferences, where you can set
what CPU are you going to control. If you have multiple-cores, you will
see CPU 0, 1, n...3. Click the applet then choose how would you like to use your CPU,
options are the following.* ondemand - increase the CPU usage when an application demands it, if
no applications is running the CPU will go back to the lowest frequency.* conservative - by default the CPU will use the lowest frequency,
when an application requires it, the CPU frequency will increment
gradually.* powersave - The CPU will always run on the lowest frequency even if
an application launches, this is suitable for battery powered hardware
like laptops and smaller computers to save more battery life.* performance - The CPU will always run on the highest frequency even
if no applications is running or requires it. This is recommended if you
require CPU intensive processing like compiling, rendering, running
games, etc.Additionally you can install the 'laptop-mode-tools' package by running:
'sudo pacman -S laptop-mode-tools'
then insert 'laptop-mode' in your rc.conf to start the service
automatically upon boot.'sudo nano /etc/rc.conf'
then add the line, 'laptop-mode' in the DAEMONS=(... ) list
so the line
'DAEMONS=(@syslog-ng @netfs @crond dbus hal ...)'
will become
'DAEMONS=(@syslog-ng @netfs @crond dbus hal laptop-mode ...)'
additionally you can add the '@' to start it on background or '!' to not
start it.Posted 10 months ago # -
