Hey facepunch, does anybody know of a linux distro that has decent power management unlike Ubuntu? I can't wait until 12.04 in April I would like to be able to run Linux on my netbook sometime soon.. Windows 7 starter is becoming a burden. I have a 3 cell battery which provides about 4 hours of constant usage in Windows, 6 if there is no I/O activity. Unfortunately that translates into 2 hours in Ubuntu 11.10
1.66Ghz N455 Atom, 64Bit instruction set with a 250GB HDD. I have a 8GB flash drive that I can use to install it with.
There are many things you can do on linux regarding power management. I don't know what all distros call it, but I've always known it as laptop mode. You can configure it to throttle down many parts of your system giving you a lot of extra battery life depending on what you do.
I would assume it wasn't enabled or auto-configured properly on your install.
You should be careful with that tho. Sometimes, if there's bad support for your hardware you may hit a few bad road bumps.
I don't think this is a very likely issue. If you want to use ubuntu, you can try to look up on how to set up proper power management with it.

You can also set your laptop's CPU to throttle when not in use.
I was doing some research, found AuroraOS and Fubuntu, which are rather neat because they move /tmp and a couple mother constantly accessed folders to ram reducing disk wakeups. Fubuntu is made by the creator of Jupiter power control tool. Looks like I will be trying out one of those pretty soon.. Unity is garbage anyways!
I'm sorry Windows... I.. I'm formatting my drive.. its not you... well it is you.. just just get out :'(
Power management is a tricky thing in linux. There are many ways to get it right, and different users have different requirements on the matters.
If you want to go the Arch route, the wiki has a [url=https://wiki.archlinux.org/index.php/Category:Power_management_(English)]great category page[/url] on power management. From there, just read up on the tools available and tweak things to your liking.
Personally, I think [url=https://wiki.archlinux.org/index.php/Laptop_Mode_Tools]laptop mode tools[/url] is the best thing that has ever happened, and I use mostly just that. With some acpi and some hdparm tweaks to cool the aggressive spindown.
