Yeah, like a fool I let the software update install Battery Update 1.3.
Now my MBP's battery is totally screwed up. It shuts itself off even if there is
50% of battery remaining.

Still waiting for a fix from apple.
A warning to all of y'all to read the support forums before install mac-breaking updates like this.

Okay, I found out that the problem is software, not hardware that's one thing for sure. This is from reading the support forums as well as trying the battery out on my friends laptop. Still gives a pretty respectable 2:30 watching dvds.
Now i've to wait for apple to release a damn firmware update.
