suspend

I am unable to change power settings so that when I close the lid the battery stops consuming energy.

There are three options in the power settings menu:

When the screen is closed: 1 Do nothing 2 Pause 3 Sleep

First I could not change anything. I see all the options but I could not click on option 2 and 3. (grey text instead of black)

I already made it possible to put in to sleep mode. But I can't pause (suspend) the laptop.

Anyone an idea?

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.

Why does my laptop resume immediately after suspend?

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I seem to be having some problem with suspend mode. Every time I try to suspend my laptop, it just locks the screen. Or maybe it successfully suspends just to resume only an instant after. What could cause such a behaviour? I'm running 32-bit Ubuntu 12.04 with the 3.2.0-25 kernel on a HP dv5-1178er… >>> More
