I had (have) and iBook too and even with Debian the standby power =

management was better than that on any modern PC laptop I've had. Dunno =

about 1yr uptimes, many Mac OS X upgrades/patches require a reboot, =

perhaps the clock had been changed and this made it look like it was up =

for a year?

On my Dell laptop I use swsusp2 (http://softwaresuspend.berlios.de/) to =

save the machine to disk and the laptop hasn't been fully rebooted in =

over a week now since the new kernel went in. It suspends memory to =

swapspace and fully powers down the machine. On reboot, the kernel loads =

as normal but before it gets to init, swsusp2 checks swap for a saved =

image and loads that it instead if there is one there. After that you =

can continue where you left off. Not nearly as quick as a Macs =

suspend-to-memory but being a fully off means you can change batteries =

or even boot in to Windows...

It would be pretty straightforward to rig an ACPI close-lid event to =

trigger hibernation though I prefer to use the Dell's suspend button to =

hibernate as I often use the laptop with the lid closed (remote access =

or laptop sized iPod) to save power.
