The PowerBook G4 is a series of notebook computers that was manufactured, marketed, and sold by Apple, Inc. (then Apple Computer, Inc) between 2001 and 2006 as part of its PowerBook line. It uses the PowerPC G4 processor, initially produced by Motorola and later by Freescale, after Motorola spun off its semiconductor business under that name in 2004. The PowerBook G4 had two different designs: one enclosed in a titanium body with a translucent black keyboard and a 15" screen; and another in an aluminum body with an aluminum-colored keyboard, in 12", 15", and 17" sizes.
Between 2001 and 2003, Apple produced the Titanium PowerBook G4; between 2003 and 2006, the Aluminum models were produced. Both models were hailed for their modern design, long battery life, and processing power. When the Aluminum PowerBook G4s were first released in January 2003, however, only 12 and 17-inch models were available. The 15-inch retained the titanium body until September 2003 when a new aluminum 15-inch PowerBook was released. In addition to the change from titanium to aluminum, the new 15-inch model featured a FireWire 800 port, which had been included with the 17-inch model since its debut nine months earlier.
The PowerBook G4 line was the last generation of the PowerBook series, and was succeeded by the Intel-powered MacBook Pro line in the first half of 2006.
The first generations of the PowerBook G4 were announced at Steve Jobs' keynote at MacWorld Expo in January 2001. They featured a PowerPC G4 processor running at either 400 or 500 MHz. They were just 1 inch (25 mm) deep, 0.7 inches (18 mm) shallower than their predecessor, the PowerBook G3. The PowerBook G4 Titanium also featured a front-mounted slot-loading optical drive into which optical discs (initially DVDs or CDs) could be inserted. The notebook was given the nickname "TiBook", a blend of the words titanium, the material used for the computer's case, and the brand name PowerBook, the name of the computer.
Industrial design
The initial design of the PowerBook G4s was developed by Apple hardware designers Jory Bell, Nick Merz, and Danny Delulis. The ODM Quanta also helped in the design. The new machine was a sharp departure from the black plastic, curvilinear PowerBook G3 models that preceded it. Apple's industrial design team, headed by British designer Jonathan Ive, was to continue toward minimalistic designs—the Titanium G4 laid the groundwork for the Aluminum PowerBook G4, the MacBook Pro, the Power Mac G5, the flat-screen iMac, the Xserve, and the Mac mini.
[edit] Quality issues
The hinges on the Titanium PowerBook display are notorious for breaking under typical use. Usually the hinge (which is shaped like an L) will break just to the left of where it attaches to the lower case on the right hinge, and just to the right on the left hinge (where the right hinge is on the right side of the computer when the optical drive is facing you). When the 667 MHz and 800 MHz "DVI" Powerbooks were introduced, Apple changed the hinge design slightly to strengthen it. At least one manufacturer began producing sturdier replacement hinges to address this problem, though actually performing the repair is difficult as the display bezel is glued together. In addition some discolouration, bubbling or peeling of paint on the outer bezel occurred, notably around the area where the palm would rest whiles using the trackpad. This appeared on early models but not on later Titanium PowerBooks.[citation needed]
[edit] Display issues.
The video cable is routed around the left side hinge. With heavy use this will cause the cable to weaken. Many owners on the internet have reported display problems such as random lines or a jumbled screen. Few have replaced just the video cable to successfully resolve this problem. There is also a backlight cable that might fail. Tinkerers would try replacing either or both cables before buying expensive LCDs.
