SMC fix for "Service Battery"?

    The battery on my 3 y.o. MBP recently started displaying "service battery". It happened abruptly and after only 500+ cycles, half of the expected amount for this type of battery.
    I did the standard shift-ctrl-opt and power boot procedure and 3 full charge/discharge cycles and it didn't do anything.
    I remember reading somewhere that you can do an SMC reset where you unplug the battery, connect the magsafe and press the power button (or something like that) as a last resort. Anyone know anything about this?

    Nothing you can do can change your service battery message. It simply means that your battery health has dipped below a certain percentage (I believe the message appears at 70%, but I could be wrong) and that it needs replacing.

    Now, you don't need to run out and buy a new battery. Just keep in mind that when nearing their end-of-life, LiPo batteries can swell quite a bit and this could damage your computer. If your trackpad ever becomes hard to click, have your battery replaced quickly, as it has started to swell.
