Instead of removing the battery, you can instead just unplug the machine, and right next to the battery, to the right of it, you will see two little solderings that mold just a tad out from the motherboard. I believe it says CLTRST or something like that. Just use a flathead screwdriver to connect them when the power is off and unplugged. Then plug her back in and she'll be cleared! Viola! Simple, huh?
