DIsabling hardware components

Lockheed · 2011-09-26 13:30:09

I am using Arch on a laptop and when on battery, I would like to have an option to turn of particular hardware components, for example PCMCIA slot, WiFi card, Bluetooth, sound card, etc.

I want to achieve the same effect like disabling a device in Device Manager in Windows, so it does not draw any power.

How can I achieve this?

Maybe make a script to unload all the drivers you don't need?

But I am not sure it would disable radio. I found a command for wifi, but need one for other components, too:

sudo iwconfig wlan0 txpower off

If you unload the driver, the radio will be disabled

Ok. Can you tell me what are the driver (or should these be modules?) names for pcmcia, express card, dvdrom, bluetooth and firewire?

I think for the sound card it would have be be dedicated disable command, as unloading the driver could cause too much config damage.
