So I installed Arch this weekend, after a friend suggested I should probably move to a more technically-orientated distro than Ubuntu. I've been on linux for a while, so I managed the install without any major problems. I have GNOME3 running with GDM as well. I have a slightly over 2 years old Acer Aspire 5738ZG laptop which is also dualbooting Windows. On Windows, I'd get about 2-3 hours with light use. On Ubuntu I got slightly less (maybe 30 minutes to an hour). However on my fresh Arch install, it lasts about 30 minutes from full charge.
I have no idea where to start here, so any ideas or help?
Thanks!

Welcome to Arch. You will find the answer to many commonly asked questions in the wiki. Check out this topic: https://wiki.archlinux.org/index.php/Power_Management
How to post. A sincere effort to use modest and proper language and grammar is a sign of respect toward the community.

I have followed all the guides in that wiki page, including making the pm-utils scripts. I didn't modify the CPU frequency scaling, because I think that's already done by default? Is that true?
I just checked powertop, it says (while my battery is apparently at 85%):
"The battery reports a discharge rate of 34.5 W
The estimated remaining time is 0 hours, 32 minutes"

No there is no cpu scaling by default you need to install cpupower.
If you have a nvidia graphics chipset use the proprietary driver the open source doesn't perform well in powersaving.
Search on the Load_Cycle_Count harddrive problem to prevent hard drive failure.

No. Arch now uses the ondemand governor by default as recommended by upstream.

Actually cpu freq driver is "ondemand" by default, at least with 3.5 linux kernel
CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y

Do you have a dedicated graphics card?

I have a separate ATI Mobility Card, HD 4570, currently opensource driver.
I think I'm going to try the propriety driver anyway.
