Ruggedized case for iPhone (3GS only for now) that boosts GPS quality, provides minimal waterproofing, dust protection and doubles battery life.
If you’re having a problem where your MacBook Pro seems to randomly shut down when you’re running from battery, then you may have hit some dead cells and lowered the capacity of your battery. I had this problem a few months ago and got to chat to one of the Apple Geniuses (Geni-i?) about it. The problem manifested itself by just shutting down my laptop before it gave me a low power warning or anything at all. The way to tell if you have the same problem as me is:
- Click the Apple Menu
- Click “About This Mac”
- Click “More Info”
- Select “Power” in the left pane
- Under “Battery Information” look for “Full Charge Capacity (mAh)
Apparently this number should be up over 5000 on a healthy battery. When mine died, that number was around 3000 from memory. Currently mine is at 5440. If your battery has a low full charge capacity, then it’s likely it failed, and if you take it back to Apple they will (hopefully, as they did for me) replace it with a brand new one, free of charge.
Hope that helps someone.
