added power management section
=== Hardware issues ===
 
==== Power Management ====
 
At this stage the directory `/sys/devices/system/cpu/cpufreq` is empty, so it seems there is no integrated power management.
 
There is also no way to turn off touch detection. Still, you can
 
<pre class="shell">
# Turn off screen
echo 0 > /sys/class/backlight/lcd-backlight/brightness
# Turn on screen
echo 250 > /sys/class/backlight/lcd-backlight/brightness
 
# Force reboot
echo b > /proc/sysrq-trigger
# Turn off screen and suspend (deepsleep?)
sudo su -c "echo 0 > /sys/class/backlight/lcd-backlight/brightness" && exec pm-suspend
 
#disable two cores (not sure if temperature decreases)
echo 0 > /sys/devices/system/cpu/cpu{2..3}/online
</pre>
==== Audio ====
==== Phosh ====
 
Power button does not turn off the screen.
Epiphany does not load pages, while qutebrowser works and renders well but sometimes crashes.If the interface hangs (does oftenrandomly every few minutes of usage), restarting LightDM with <code>sudo rc-service lightdm restart</code> has no effect. ===== Browsing =====- Epiphany does not load content;- Chromium crashes;- Firefox works but crashes after a while;- Qutebrowser works well but crashes after a while;- Vimb works but crashes after a while;- Netsurf never crashed.- Dillo will probably work, too.
==== Plasma Mobile ====
==== Useful aliases ====
<pre class="shell">
# Turn off screen
echo 0 > /sys/class/backlight/lcd-backlight/brightness
# Turn on screen
echo 250 > /sys/class/backlight/lcd-backlight/brightness
 
# Force reboot
echo b > /proc/sysrq-trigger
# Turn off screen and suspend (deepsleep?)
sudo su -c "echo 0 > /sys/class/backlight/lcd-backlight/brightness" && exec pm-suspend
 
# Restart lightdm (has no effect)
sudo rc-service lightdm restart
 
# Input devices
cat /proc/bus/input/devices
 
#disable two cores (not sure if temperature decreases)
echo 0 > /sys/devices/system/cpu/cpu{2..3}/online
