Laptop battery

[heimo]

What you want is laptop-mode (it's in universe, you need that in
/etc/apt/sources.list)

(lots of other good advice there too!)


Code:
--------------------
    sudo apt-get install laptop-mode-tools
--------------------
 

If you have ACPI enabled in laptops BIOS, this should be able to spin
down your laptops hard disk and do writes in batches. This approach has
caveats - you risk losing some data if you lose power / crash or
something like that. You need to read 
Code:
--------------------
    man laptop_mode
--------------------
 I don't know if it enables itself, so 
Code:
--------------------
    sudo /etc/init.d/laptop-mode start
--------------------
 may be neccessary.

Don't hesitate to ask for more help, if neccessary.

EDIT: added -sudo
