Macbook Pro (Early 2009) hibernates when removed from wall power

After recently upgrading to Mountain Lion, I got the notification that my battery needed servicing. I went into the genius joint and they ran the usual suite of diagnostics. The battery apparently failed because it wasn't reaching a certain percentage of maximum. I expected as much since this was the original battery I had in the machine when I bought it.

So, $180 later, I have a new battery. Now, after disconnecting from wall power, my Mac hibernates, even if I am typing on the machine. I've paid two visits to the geniuses again. One reset the PRAM and the other reset the SMC. Both haven't yielded a solution. He said that since the diagnostics aren't showing the new battery to be faulty they cannot swap the battery. They suspect it's a software issue and want me to wipe the OS and reinstall from scratch. Yippee, welcome to Microsoft Windows.

I don't know the relevant system.log messages that might yield a solution. Here are the ones I can find quite easily:

If anyone has any suggestions that don't involve wiping my hard drive so I can fix this, I'd buy you a beer.
