Random is the best way to describe it, indeed! Battery is pretty much shot... I mostly use it at my desk right now, so it stays plugged in. Rather disappointed in the battery.. it started having capacity issues around month 13 of owning said computer (but the battery had about 5 cycles on it when I first purchased it, so I didn't think much of it.) I didn't purchase the extended warranty, and so far I've lucked out, excepting the battery. Normally I run Windows 7 under Boot Camp on it when I play games, and use Mac OS X for my productivity apps... with the majority of its use being for gaming Windows side. I run my laptop on a cooling stand with fans 100% of the time that I am gaming, so I'm able to keep temperatures under control. So, today I was playing StarCraft 2, and BAM my laptop shut down on me without warning. I cursed to myself because I thought I'd forgotten to plug in my laptop again... but then I noticed power cord was still connected! Overheated? I thought. Checked the temperature of the keyboard and underneath the computer... nothing out of the ordinary. It was hot, but not the scalding hot that I've felt when it did manage to overheat. I guess my question would be... how does the MBP's power management work under Windows? I thought I'd seen somewhere that the newer MBPs don't run on battery when they're fully charged, and instead draw power straight from the power cord. Does it work any differently through Boot Camp? My initial theory is that the battery's power was being drained faster than the power cord could charge it by playing a CPU/GPU intensive game, but if that were the case, shouldn't the power cord be providing enough power to stay on? Not quite sure what happened. About to go play some more games to see if I can get it to happen again. This is the first time I've ever had a random shutdown like this that wasn't because it was running on battery or that it had overheated. Any thoughts?
