Yesterday I just picked up my new batteries bought directly from Toshiba Canada. It was so cheap that I ordered two of them.
It was a great deal! The total amount, including taxes and shipping (free!) was 57,00 Canadian dollars. With the battery that came with my laptop (a Satellite A100 0fh model), after 1 year, i only got near 1h 20m of battery life, with wireless and sound. With the new batteries, I can now go up to 3h!
Last week I played around with Intel’s powertop tool and realized that i could improve my system to use less power and have more autonomy. I started disabling bluetooth, cupsys (as i don’t use the printer services all the time), disabling the boot splash (so the system boot up more quickly) and finally, the tifm_7xx1 and tifm_core, which enables my Texas Instuments 5-1 Card reader (On the linux box, only SD cards work) by putting them into the modules blacklist.
There’s couple of other options Intel’s powerop told me to do like usbcore.autosuspend=1 on kernel boot arguments, run iwpriv eth1 set_power 5 for the wireless card, run “echo 1500 > /proc/sys/vm/dirty_writeback_centisecs” i found here some explanations about all that.
But i’m not doing it yet… by the way, Intel’s powertop is an interesting piece of software!
What about you guys? As we are on an “energy save year”, what tips and tricks do you have to save your laptop battery? Share with us!

Since you asked:
(On the linux box, only SD cards work)
I found some explanations about all that here.

Other than that you are doing pretty well.
When I bought my Toshiba Satellite 2410 laptop, I wanted to buy some batteries but I ran out funds. And each battery cost around $100-$120. But in the end, I killed my laptop’s fan by running Gentoo on it… or rather emerging and compiling all the latest and greatest updates. Mea culpa. Should of run Debian or Ubuntu like one of my friends suggested.

Your English is pretty great! A few notes:
“I” is a capital letter even in the middle of a sentence: “Yesterday I just picked up my new batteries”.
“Autonomy” isn’t really the right word for how long your battery lasts: people would normally say “battery life”.
“Which” has an extra (silent) “h” in it: “the tifm_7xx1 and tifm_core, which enables…”
“On the linux box, only SD cards work” — there’s more than one SD card, so it’s “work” rather than “works”, because “it works” but “they work”.
“we are on an ‘energy save year’” — singular “year”, not plural “years”.
“So fell free to correct” -> “So feel free to correct”.
“help-me” doesn’t have a hyphen in it: “help me”
Sorry, I feel quite unkind now — I can’t speak any Portuguese at all!
