Re: Laptop power saving script for #! & Debian

How much extra battery life are you getting with this?

Re: Laptop power saving script for #! & Debian

Thanks for posting this, hardran3.  I, too, have been disappointed with battery life in CrunchBang; Ubuntu Netbook Edition is noticeably better.  I tried installing gnome-power-manager, which makes it a bit better, but your script looks to go much deeper.  I'll try it on my Acer 1810TZ and report back.

Re: Laptop power saving script for #! & Debian

I'm wondering how you run the script? You have to be root to execute it.

Or does laptop-tools make it run every time the power is unplugged?

Re: Laptop power saving script for #! & Debian

Re: Laptop power saving script for #! & Debian

^ huh, that's really weird. maybe it's because i'm using testing repos? But when I reinstalled pm-utils it made me remove laptop-mode-tools (even though in synaptic there were no conflicts on the package details) and when I originally installed laptop-mode it made me remove something (don't remember what, but it must have been pm-utils)... oh well. Like you said, it works! So I don't question

Re: Laptop power saving script for #! & Debian

@jelloir...that makes sense but it just doesn't show up...in fact laptop-mode-tools only conflicts with noflushd.

BUT::: I just checked pm-tools and that DOES conflict with laptop-mode-tools. So that must have been causing the problem and you're probably right as to why. Thanks for clearing that up!

Re: Laptop power saving script for #! & Debian

Script worked well on my EEE 1001pxd.  I ended up lowering  backlight brightness. I found your setting a bit to bright for my screen.

Went from around 5h30m to 6h40 min.

My watt usage went from the low 9's to the mid 8's

Thanks!

Re: Laptop power saving script for #! & Debian

wow, this is great! I just did it and have been running my laptop with the screen brightness at 100% downloading lots of files and on the internet for 10 minutes and my battery is still at 100%!! it used to be that by now it would be at 95!

I love all of your hacks to make things better. I just added the liquorix kernel as well and now a couple of things work better than they did ever before. and faster I'm a slow typer so it's been about 20 minutes now and I'm still at 100!!

my battery, honestly has a longer battery life than in my windows 7 now.

thank you soooo much!!

Re: Laptop power saving script for #! & Debian

Many thanks I shall give this a go.  I'm only getting just under 2 hours (with wireless on) at the mo.  Which isn't too good for a Thinkpad!
