Hi, I currently have a Powerbook 12inch 1.5GHz (Rev. D). Since the release of Tiger, a bug in the Apple Trackpad driver (for Rev. D Powerbooks only I believe) has caused a process called KernelTask to be constantly at 8% (or similar number)CPU Usage when the trackpad is enabled, obviously lowering battery life. This issue is described here: http://www.macosxhints.com/article.php?story=20050808165343661 I know there is a workaround by using the SideTrack driver which lowers the KernelTask process down to 1%CPU, but I would rather be using the Apple Driver so I can enable 2 finger scrolling. Does anyone know if this issue has been resolved in 10.4.3? Thanks.
