 +===== Notes =====
 +The Scorpio 640GB has a head park problem that also manifests itself on the pre-installed windows (you hear clicking sounds from the drive every few seconds, during which the drive is inaccessible),​ and is also reported on other computers. ​ I fixed it by turning off its powersave functionality (sudo hdparm -B 255 /dev/sda).
 +
 +The open source video driver also worked, though I did not test it extensively.
 +
 +I had to install Madwifi manually in ubuntu 9.10.  I followed [[http://​art.ubuntuforums.org/​showthread.php?​t=1163380|these instructions]]. ​ I used jockey to enable it, but it turned out both madwifi and ath9k were running at the same time even after reboot. ​ This was fixed after putting a line "​blacklist ath9k" in /​etc/​modprobe.d/​blacklist.conf.
 +===== Summary =====
 +With CPU throttling defaulting to "​balanced"​ and HD powersave off, battery life is more than 2h 40m when I'm just web browsing.
