I'm new to Ubuntu, and I've just installed Ubuntu 11.10, and I must say I really like it a lot. I'm getting used to Ubuntu faster than I thought but the only issue I'm having is the power consumption.

I have a " dell 15R with BIOS a07" and I uninstalled Ubuntu 11.04 because of some glitches I hated. None of those appear on this Ubuntu but now my computer discharges way too quick. when I check the power icon, it states that I have like 3:45 min remaining, which is fairly the same as what win7 and Ubuntu 11.04 used to tell me but 15 min later I check again and it gives me only 1:15 min remaining. Also, my computer seems to get a lot hotter than it used to.

Is there more options to control the power usage on my laptop?

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
