Does the Rev B Air have a "cmos/smc" battery?

    is everything!
    I couldn't take the "heft" of the 13" pro so I bought a rev b refurb with the ssd. I've been having some weird battery issues that I don't remember having with my previous Rev B so I dropped it off with a "genius".

    When the battery completely died and it was in hibernate mode, it would take more then 9 hours to fully recharge. When I turned it back on after a complete battery drain the clock would reset back to 1/1/2000.

    Also, putting it to sleep at 100% and opening it 8-10 hours later the battery would be less then 20%

    The "genius" said that the macbook air doesn't have a backup battery to remember things like time and date. When the battery completely goes, that's it. They also couldn't find anything wrong with it. Sounds a bit fishy to me.

    No, that battery is integrated into the main battery.
