]]>That's so cool. I'm going to get a laptop now. If it's not compiled into Arch's 2.6.6, I'm going to be pissed. I haven compiled a kernel myself in 2 months now, and I don't plan to compile much of anything when we have such great package maintainers to do these things for us!
I don't think there's even an option for that. Laptop mode is just a feature of the 2.6-kernel (maybe 2.6.x; I don't rememeber exactly) series. In case you've missed this, here's a link to a PKGBUILD by phrakture: http://bbs.archlinux.org/viewtopic.php? … laptopmode
EDIT: Seems your lucky, it turns out the feature starts with kernel 2.6.6
]]>Laptop mode will spin down your drive and buffer all writes rather than spinning it back up. When you do a read that requires data from the disk, it will spin up the disk, perform the read, perform all pending writes and spin the disk back down. After a user-defined interval (default 10 minutes) it will spin the disk up just to flush writes -- I prefer to set it to an insanely long time and then just tell it to flush manually at appropriate times (by toggling laptop mode off for a moment).
I wasn't aware there was such a mode - Does anyone know where the config option is?
