    I got a 2.2 MBP at the end of October and I've just noticed that when I leave my laptop switched off the battery still discharges. Having just left my MBP off for 12 days while I was on holiday I turned it on (it was plugged in before I turned it on so battery drain was not during bootup - the power lead led went amber before I'd pressed the power button) an it was showing 91% full. I spoke to the applecare people who said the %age is just an estimate and this is normal, I've only had windows laptops before but they have always shown full battery after sitting so I'd like to ask you lot ... is this your experience or are they spinning me a line ?

    I'm going to do some experiments noting the Full capacity Ah and the current Ah on shutdown tonight with startup tomorrow morning and present that to applecare unless this is "normal" behavior.

    I turn off my new SR macbook every night. It will keep 20 hours off every day. And this 20 hours cost 1% battery capacity!!!

    So yours is better than mine.
