Also, you can make these scripts run whenever you're on battery power if you add them to /etc/laptop-mode/batt-start. For example:
Code:
root@portarisk:/etc/laptop-mode/batt-start # ls -l
total 4
-rwxr-xr-x 1 root root 805 2010-02-16 17:09 3810t_power_save.sh
root@portarisk:/etc/laptop-mode/batt-start # cat 3810t_power_save.sh
#!/bin/bash

# Description: Enables every power saving feature I know of

echo 10 > /sys/module/snd_hda_intel/parameters/power_save
echo Y > /sys/module/snd_hda_intel/parameters/power_save_controller
echo 1 > /dev/dsp # Gotta make a sound to turn it on
# Enable various kernel power saving features
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
# Enable SATA power management
for i in /sys/class/scsi_host/*; do echo "min_power" > $i/link_power_management_policy; cat $i/link_power_management_policy; done
# Enable Wifi power management
/sbin/iwconfig wlan0 power on
# Enable the most aggressive hard drive power savings
hdparm -B 1 -S 12 /dev/sda # Note: '-B 1' does work on the 3810T hard drive but doesn't save you much
# Enable USB autosuspend for all USB devices
for i in /sys/bus/usb/devices/*; do echo 1 > \$i/power/autosuspend; done
for i in /sys/bus/usb/devices/*; do echo auto > \$i/power/level; done
You can also add a "turn power saving features off" script to batt-stop to speed things back up again on AC power. Example:
Code:
root@portarisk:/etc/laptop-mode/batt-stop # ls -l
total 4
-rwxr-xr-x 1 root root 325 2010-02-16 17:10 3810t_power_save_off.sh
root@portarisk:/etc/laptop-mode/batt-stop # cat 3810t_power_save_off.sh
#!/bin/bash

1. Will those scripts in start and stop folders run automatically, as I do not see any instruction where it mentions to laptop_mode to launch the 3810t_power_save.sh in corresponding modes!
2. Is the "laptop_mode start" always running, or it has to be launched by including the command in "/etc/init.d/boot.local"? Also it be good to point that laptop_mode is not installed by default, and needs to be installed, hence the question.
I read that them scripts can be as well added to "/etc/init.d/boot.local", and not the /etc/laptop-mode/..." folders.
As per sound problem, I didn't install anything extra, just launched "alsamixer" > F4 > and maxed the rigth channel (0 for left channel) in Capture, and Input Source set to Mic. This way Skype works perfect.
For ATI, select discrete in BIOS, as there is no switching support for now, and install the driver from System>Admin>Hardware Drivers.
Riskable/Admin >> It be really handy to have all the instructions, step-by-step posted on first post and pinned, and to include other tweaks as well, related to 3810T/TG models.
Thanks.
OpenSource is good for you and for the world!
