Macbook Battery Life
 
Standard Maintenance
For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her notebook on the train, then plugs it in at the office to charge. This keeps the battery juices flowing. If on the other hand, you use a desktop computer at work, and save a notebook for infrequent travel, Apple recommends charging and discharging its battery at least once per month. Need a reminder? Add an event to your desktop’s iCal. When your battery no longer holds sufficient charge to meet your needs, you may choose to replace it.
 
Optimal Setting
You can choose to use your Apple notebook in a way that maximizes its battery life.
  • Energy: The Energy Saver control panel offers several settings that determine power levels for your PowerBook. Your portable knows when it’s plugged in, and runs accordingly. When on battery power, it will dim the screen and use other components sparingly. If you change this setting to maximize performance, your battery will drain more quickly.
  • Brightness: Dim the screen to the lowest comfortable level to achieve maximum battery life. For instance, when watching a DVD on an airplane, you may not need full brightness if all the lights are off.
  • AirPort Wireless: AirPort consumes power, even if you are not using its features to connect to a network. You can turn it off in its control panel to save power.
  • Bluetooth Wireless: Likewise, you can turn off Bluetooth to maximize your battery life, as it also consumes power when not in use.
  • Applications and peripherals: Disconnect peripherals and quit applications not in use. Eject CDs and DVDs if not currently accessing them.
 
Long-Term Storage
If you don’t plan on using your notebook for more than six months, Apple recommends that you store the battery with a 50% charge. If you store a battery when it’s fully discharged, it could fall into a deep discharge state, which renders it incapable of holding any charge. Conversely, if you store it fully charged for an extended period of time, the battery may experience some loss of battery capacity, meaning it will have a shorter life.


Stuck Disk on the MLTI Macbook

The standard stuff When a disc won’t eject from your Mac, try the following:
1.) Press and hold the Eject key,
2.) Right-click on the disc icon on the Desktop and select “Eject” from the menu,
3.) Drag the disc icon to the Trash. Disk Utility Launch Disk Utility (Applications > Utilities) and select the troublesome CD or DVD in the sidebar. Click the Eject button at the top of the window.

The self-fixing Mac Shut down your Mac, turn it back on, and let it sit for 10-15 minutes. Make sure the power cord is plugged in as you do this and the disc just might pop out on its own.
