root@vi-notebook:/home/vi# laptop_mode start force
Laptop mode 
enabled, not active

How to start laptop mode? It starts successfully when AC adapter is removed, but not by explicit command.

The system is GNU/Linux Debian i386 squeeze (not up to date), 2.6.30-zen2-31270-gc7099db-dirty, Acer Extensa 5220.

Update:
Changed to ENABLE_LAPTOP_MODE_ON_AC=1 in /etc/laptop_mode/laptop-mode.conf, now it is turned on always. But I can't turn it off with laptop_mode stop force, it stays turned on anyway.

How do I turn it off again?

Update 2:
Implemented hardcore solution, "radical laptop mode": http://vi-server.org/vi/code/kernel/0003-block-Introduce-hung-iosched.patch

It just forces HDD to be off until I explicitly allow access to it again (all requests get hung).

@vi - You should edit your question instead of adding information in the comment field, makes it easier to read. – Nifle Mar 16 '10 at 7:24
    
Well if "ENABLE_LAPTOP_MODE_ON_AC=1" works on then just reverse when you want it off "ENABLE_LAPTOP_MODE_ON_AC=0" – Iceking007 Feb 17 '11 at 15:02
