The same size and weight its 1.0 and 1.25 GHz predecessors, the 2004 15″ PowerBook G4 runs faster (at 1.33 and 1.5 GHz) and moves to the Mobility Radeon 9700 graphics processor.
The 1.5 GHz model has the same illuminated keyboard found on the 17″ PowerBook G4. The SuperDrive on the faster PowerBook officially supports 4x DVD burning, twice as fast as on the 2003 model. The SuperDrive model is priced at $100 less than its predecessor.
Battery life is rated at 4.5 hours.
Closed Lid Mode: G4 PowerBooks support “lid closed” (or clamshell) mode, which leaves the built-in display off and dedicates all video RAM to an external display. To used closed lid mode, your ‘Book must be plugged into the AC adapter and connected to an external display and a USB or Bluetooth mouse and keyboard (you might also want to consider external speakers). Power up your ‘Book until the desktop appears on the external display and then close the lid. Your ‘Book will go to sleep, but you can wake it by moving the mouse or using the keyboard. The built-in display will remain off, and the external monitor will become your only display. Since all video RAM is now dedicated to the external monitor, you may have more colors available at higher resolutions. The TiBook is designed to run safely in closed lid mode, but if yours runs hot (perhaps due to overclocking or high ambient temperatures), you may want to open the lid when in closed lid mode: The screen will remain off and the computer will more readily vent heat from the CPU.
To resume use of the internal display, you need to disconnect the external display, put the computer to sleep, and then open the lid. This will wake up your ‘Book and restore use of the built-in display.
