The PowerBook G4 is a series of notebook computers that were 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 latest version of OS X any PowerBook G4 can run is Mac OS X Leopard, released in 2007.[1]

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. They were among the first laptops to use a widescreen aspect ratio.The PowerBook G4 Titanium also featured a front-mounted slot-loading optical drive.[2] 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.[3]
[edit] Industrial design
The initial design of the PowerBook G4s was developed by Apple hardware designers Jory Bell, Nick Merz, and Danny Delulis.[4] The ODM Quanta also helped in the design.[citation needed] The new machine was a sharp departure from the black plastic, curvilinear PowerBook G3 models that preceded it. The orientation of the Apple logo on the computer's lid was switched so it would 'read' correctly to onlookers when the computer was in use. PowerBook G3 and prior models presented it right side up to the computer's owner when the lid was closed. Apple's industrial design team, headed by British designer Jonathan Ive, converged around a minimalist aesthetic—the Titanium G4's design language 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 while 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.

In 2003 Apple introduced a new line of PowerBook G4s with 12, 15, and 17-inch screens and aluminum cases (prompting the new moniker "AlBook"). The new notebooks not only brought a different design to the PowerBook G4 line but also laid down the foundation for Apple’s notebook design for the next five years, replaced initially in January 2008 by the MacBook Air and the subsequent MacBook and MacBook Pro redesigns in October. The 15" titanium model was still available until September 16, 2003, when the Aluminum model replaced it. Notably, the 12" model brought a welcome return to the Apple subnotebook configuration, conspicuously lacking in their product line since the discontinuation of the PowerBook 2400 in 1998. While the titanium PowerBook G4s were capable of running Mac OS 9 or Mac OS X operating systems, the aluminum PowerBook G4s could only boot in Mac OS X from startup. Both series of machines could run Mac OS 9 in Classic mode from within Mac OS X.
[edit] Industrial design
The aluminum PowerBook G4 was designed by Apple's Vice President of Industrial Design, Jonathan Ive, and used a radically different design from the preceding titanium models. The most obvious change was the use of aluminum, not titanium, to manufacture the body. The keyboard, which was originally black, was changed to match the color of the body. Additionally, the aluminum keyboard was backlit on the 17" model and on one of the 15" models. The design was considered superior to most other notebooks when it debuted in 2003, and consequently, it made the PowerBook G4 one of the most desirable notebooks on the market. The external design of Apple's professional laptops continued to remain similar to the aluminum Powerbook G4 until the Spotlight on Notebooks event on October 14, 2008.
[edit] Quality issues
Some owners have experienced failure of the lower memory slot, with the typical repair being the replacement of the logic board. Apple had started a Repair Extension Program concerning the issue,[7] but it has been noted that some models displaying the issue have not been included. This leaves certain PowerBook G4 owners with only a maximum of 1 GB of RAM to use instead of a full 2 GB.
Apple previously had a Repair Extension Program to fix the "white spot" issue on its 15" PowerBook displays.[8]
There has also been a rash of reports concerning sudden and pervasive sleeping of 1.5 and 1.67 GHz models known as Narcoleptic Aluminum Powerbook Syndrome.[9][10] Symptoms include the PowerBook suddenly entering sleep mode, no matter what the battery level is or if it is plugged in. One cause is the ambient light sensing, and associated instruction set coding, with possible keyboard backlight and sleep light issues accompanying the so-called "narcolepsy". Another cause is the trackpad heat sensor monitoring the trackpad; system logs report "Power Management received emergency overtemp signal. Going to sleep.".[citation needed]
To correct this, service groups will often replace the logic board or power converter, but the actual fix (depending on the model) for the first cause is to replace or remove the left or right ambient light sensors; and for the second cause, disconnect, remove, or replace the heat sensor, or the entire top case which holds the trackpad heat sensor. Alternatively, there are reports which detail success in removing certain sensor kernel extensions or rebuilding the kernel using the Darwin Open Source project after commenting out the relevant sleepSystem()
call; though permanent solution of the sleep issue in this manner is little documented.[11]
The 1.67 GHz model may suffer from manufacturing or design defects in its display. Initial reports pointed to this only being a problem with type M9689 17" PowerBooks introduced in Q2 2005, but then this problem was also seen in displays replaced by Apple Service Providers in this period (e.g. because of the bright spots issue). The devices were the last 17" models shipped with the matte 1440×900 pixel low resolution display. After many months of usage, the displays may show permanently shining lines of various colors stretching vertically across the LCD. Often this will start with 1-pixel wide vertical lines being "stuck" in an "always-on" mode. Various sites have been set up documenting this issue.[12][13] and a campaign seeks to get Apple to acknowledge that a defect exists. Posts regarding this in Apple forums have been heavily censored. There has been no official word from Apple on the issue.
On May 20, 2005, Apple recalled 12 inch iBook G4, and 12 and 15 inch PowerBook G4 batteries (model number A1061, first 5 characters HQ441 – HQ507 for the iBook, model # A1079, serial # 3X446 – 3X510 for 12" PowerBook, model # A1078, serial # 3X446 – 3X509.)[14] They were recalled due to short-circuiting which caused overheating and explosion. The batteries were made by LG Chemical, in Taiwan and China. Apple has removed the recall from its website, but it is possible to get a new one by calling them.

[edit] Discontinuation
The PowerPC G5, which powers Apple's now-discontinued Power Mac G5 and iMac G5 computers, proved to be too power-hungry and heat-intensive to use in laptops.[15] This, along with the stalling development of the G5, is said to be one of the main reasons for Apple's transition from PowerPC to Intel processors.[16] On January 10, 2006, Apple released its first Intel-based laptop, the 15" MacBook Pro.[17] A 17" version of the MacBook Pro followed on April 24, 2006.[18] The 12" PowerBook G4 and the G4 iBook were discontinued and replaced by the 13.3" MacBook on May 16, 2006, ending the whole PowerBook line.[19] However, a replacement for the 12" subnotebook form factor was not immediately forthcoming; the MacBook Air, released in 2008, served as an indirect replacement while the 13" MacBook Pro released in 2009 is the direct replacement for the 12" PowerBook G4.[20][21]
Apple CEO Steve Jobs noted during the introduction of the MacBook Pro that Apple wants the word "Mac" in the name of all its Mac hardware products.
