- PowerBook 500 redirects here; there was never a "PowerBook 500".
The 500 series encompass the following PowerBooks:
The most significant change to the new PowerBooks was the replacement of the trackball with the trackpad. The trackpad has since been praised. Most people prefer the trackpad to the trackball. Switching over to the trackpad is exceptionally easy.
The PowerBook 500 series can accept one Type III PCMCIA card or two Type II PCMCIA cards. Initially, however, the Macintosh system software restricted use of Type II cards to just one card at a time.
The new battery that accompanies the 500 series PowerBooks -- the PowerBook Intelligent Battery -- is a multicelled NiMH power pack with a built-in chip which tracks power usage and tells the PowerBook how to manage and preserve power. The new battery lasts 2 - 4 hours per charge, depending on how the user actually uses the laptop.
Additionally, the PowerBook 500 series come with two battery compartments, one of which can be removed for the usage of PCMCIA cards.
