New Netbook Packard Bell Dot S - Battery life

Hello Guys,

This is my first day with my new Netboook an Packard Bell DOt S (Atom N2600) .

It is supposed to have battery lasting 5+ hours with wifi usage.

Today I just installed #! and the battery drained it about 2 hours and 30 minutes. Even my laptop can work a lote more with batteries.

I am pretty sure ( I hope) to be an OS problem. Is crunchbang optimized for netbooks in terms of battery?
If not what I should do to fix the issue? It is the most important thng battery to a netbook

Thanks

Re: New Netbook Packard Bell Dot S - Battery life

Most probably the power regression issue relevant to linux kernel up until 3.4, right?

I would try rc6 grub mod as well, or install liquorix kernel. These will make a massive difference.

Doesn't matter that your machine is not thinkpad, its an intel thing in this post I'm suggesting, and a power regression inherent to the kernel.

Try 'e' at boot first, otherwise look at /etc/defaults/grub

Re: New Netbook Packard Bell Dot S - Battery life

^It's not an Intel, but a PowerVR graphic card, so all the rc6 stuff is useless.

@gosom: Try newer (3.6x +) kernels (liquorix, siduction-kernels), they are supposed to have improved support for power management on this card. Also, try searching for "gma3600" or "intel cedar view" in the webs...
I have the same netbook, but I barely use it (I gave it to a friend without computer). It has been getting better with newer kernels, at least performance-wise. Dunno about battery life.

I can recommend Jupiter, a small applet that lives in the notification area.
http://sourceforge.net/projects/jupiter/files/

The Wbupd8 Team maintains a ppa:
https://launchpad.net/~webupd8team/+archive/jupiter

It is by far the easiest way to maintain battery life on Linux that I have tried.

A PPA for Ubuntu. Means you have to deal with possible problems.

Ok and how I upgrade the kernel?

Is this kernel ok?

http://liquorix.net/

I would prefer to stay with sogmething more tested.

@ivanov

It has worked for me on Debian before, and I have no reason to suspect it will not work again. But if you are wary of the ppa, you can always download the source from sourceforge and build it yourself  smile

@gossom:

Maybe this:

http://crunchbang.org/forums/viewtopic.php?id=22740
http://liquorix.net/
http://siduction.org/

Though, it is of advantage to use Testing/Unstable or consider installing CrunchBang 11 Waldorf.

Re: New Netbook Packard Bell Dot S - Battery life

I will try first with the crunchbang 11. Fix the other problems and then I will consider another Kernel

Re: New Netbook Packard Bell Dot S - Battery life

I meant for the repos, #! 11 itself offers the same kernel that you can find in backports in #! 10. That means you have to try indeed some of the suggestions, stock #! 11 probably won't fix your power regression.

Re: New Netbook Packard Bell Dot S - Battery life

How's the battery life now? I asked my friend, he has about 2.5 hs of battery with siduction-xfce4 on this netbook with a 3-cell battery.
