I have a device running Ubuntu 10.04 with SSD drive and want to optimize its power consumption. As far as I understood laptop mode documentation, it is intended for conventional disk drives.

Does it make sense to configure laptop mode on Linux laptop with SSD drive in order to save power ?

You know 12.10 is available? –  pnuts Nov 28 '12 at 10:33
    
@pnuts As I wrote above "I have a device running Ubuntu ...", industrial device, so we stick to 10.04 to avoid expensive testing etc. –  tommyk Nov 28 '12 at 10:36
    
Wouldn't have mentioned 12.10 had you not mentioned 10.04! But (a) Precise Pangolin might be better for settling on (an LTS version) and (b) seems odd to be optimising and industrial device for at best very modest power savings. –  pnuts Nov 28 '12 at 10:44
    
@pnuts It makes sense to optimize power settings if the device is in 97% use cases battery powered. Another reason are our custom drivers, some of them do not work with 12.04. –  tommyk Nov 28 '12 at 12:05

I don't think it is quite necessary, since the prices of SSD is still quite high. On linux, it is more power-saving than in other commercial operating system. Futhermore, SSDs can only save up a little power, there will not be a too significant difference with the improvement of power.

Sorry I don't get what is the relation between power saving and SSD price. Can you be more specific ? –  tommyk Nov 28 '12 at 9:54
