Maximize that battery life

Sometimes I want to write for the longest time on my PowerBook, without being online. I just want to max the time I can work on a single charge.

• Turn off sound
• Turn off Airport
• Turn off Bluetooth
• Turn off internal modem and / or Built-in ethernet
• Turn the Screen brightness to a minimum
• Access the Systems preferences and click on the Universal Access. Set the display to grayscale, and Switch to White on Black.
• And click on the Energy Saver in the Systems Prefs. There you can adjust the Auto sleep, display sleep, hard disk sleep and reduced processor.

And if you also choose to use a light program like TextEdit you’ll be going for many hours before your Mac’s battery needs to recharge.
