    Just upgraded the HD to a seagate 750GB HD.. i noticed that the battery % ha stayed at 95% since charging since last night..

    Is this normal and can i purchase a better or larger battery in the near future?

    You are okay. Unless you run the battery down below 90% or so, it will only recharge back up to around 95%. Unplug it and use it down to below 90% then recharge and you should get back close to 100%. This is by design to prevent overcharging from frequent small charges.

    It's normal that your battery may stop charging between 93-99%. For details, read the CHARGING section of the following link. The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.

    i did a battery reset by turning off computer and holding control, option, and shift with power button.. seemed to fix the issue as the battery is now at 100%..
