    Yah? I close the lid at night and when I wake up, my 12" PB seems to lose 10%of the battery life?

    Is there something wrong or is that normal?

    It uses VERY little power when its asleep. About as-much as it does when u shut it off. losing 10% overnight is very normal.

    it's normal, but it sucks !

    same happens to every PB I know. A week on sleep and it's dead.
    why, oh why, won't Apple give OSX a 'proper' hibernation feature (like my WinXP laptop has)
    it's the only downside I can find to my powerbook !

    because sleep is "instant on" "instant off"... hibernation is shuting down and booting up. takes far to looonng. Im 100% sure that a similar feature will be implemented in Tiger. It would be nice to "hibernate" and finish ur work exactly how u left it a week or even months later!

    Not a PowerBook, but here's some numbers on power usage for my 800MHz G3 iBook with a 12" screen.

    What rev 12" do you have? My girlfriend sold her rev A which lost about that much and got a rev C which loses much less. My rev C 17" goes to sleep at 100% and when I get to work (about 5-6 hours later, sadly enough) it is at 96%.

    My 12" Rev C PB only loses about 4 or 5 % if it's asleep overnight. 10% sounds excessive to me.

    I never shut mine down, because a reboot takes far to lang time, and it uses more power to reboot than having it sleep for a couple of hours.

    My PB loses about 10% per day while in sleep mode - although it doesn't often go a whole day without being used! I've only turned my PB off 3 or 4 times in almost 2 years.

    For reference, try putting a Windoze machine to sleep - not hibernation, but sleep- overnight. It'll lose close to 25% overnight.

    You're doing fine.
