    Hey everyone. I hope somebody here can help me out.

    I installed the 10.5.2 update last night and I noticed today that my battery life was about half what it normally was. It would also charge really quickly, but then discharge very quickly. I took a look at the system profiler and it says my total battery capacity is 2667 mHa. I asked around and it seems that a true full charge is around 5000mHa. Leaving my computer on the charger past when it says 100% doesn't give me any extra charge. This all worked fine yesterday before I installed the OS X update. I don't have an extra battery to test whether its the battery or the computer.

    Any ideas on how to reset the full Battery capacity or do should I try going back to 10.5.1?

    Yep, didn't help. I also reset the System Management Controller with no results.
