IBook

From Wikipedia, the free encyclopedia

The original "Blueberry" iBook

The iBook is a now discontinued line of laptop computers that was developed and sold by Apple Computer, Inc. between 1999 and 2006. It was targeted at the consumer and education markets, with fewer features and lower prices than the PowerBook, and more recently, the MacBook Pro. The MacBook replaced the iBook line in May 2006.

[edit] iBook G3 ("Clamshell")

The original iBook
Type:	Laptop
Developer:	Apple Computer
Released:	July 21, 1999
Discontinued:	May 1, 2001
Processor(s):	PowerPC G3, 300–466 MHz

After much speculation, Steve Jobs unveiled the consumer-targeted iBook G3 laptop computer during the keynote presentation of Macworld Conference & Expo, New York City on July 21, 1999. The design was influenced by Apple's consumer desktop, the iMac, with a large distinctive shape, translucent clear and colored plastics. Its marketing slogan was "iMac to go".^[1]

The iBook G3 design catered to children and students. A carrying handle was built into the hinge. Apple demonstrated Phil Schiller, Apple's VP of Marketing, holding the iBook G3 while jumping off a height (onto cushions) to tout the durability of the casing. Like the iMac, the iBook G3 used a PowerPC G3 CPU, and included no legacy Apple interfaces. USB, Ethernet, modem ports and an optical drive were standard. The ports were placed uncovered along the side, as a cover was thought to be fragile. Similarly, there were no latches. The bottom surface had additional power connectors that allowed multiple iBooks G3's to be easily charged on a custom-made rack. The iBook G3 was the first Mac to use Apple's new "Unified Motherboard Architecture", which reduced the parts count (condensing all of the machine's core features into two chips) and added AGP and Ultra DMA support.

The first iBook G3 was the first mainstream computer ever designed and sold with internal wireless networking. The display bezel contained the wireless antenna, which attached to an optional internal wireless card. Lucent helped in creating this wireless capability and in establishing the industry standard. Apple released the AirPort Wireless Base Station at the same time.

There was heated debate over many things such as the aesthetics, features, weight, performance, and pricing. The iBook G3 was heftier than the PowerBook of the time, with lower specifications. Standard features like PC card slots were absent, as were long rumoured features like touch-screens, and an ultra-long battery life. The iBook was labelled "toilet seat", among other things, due to the distinctive design. Nevertheless, this same distinctive design made the iBook G3 visible in movies and televisions shows.

The iBook G3 was a commercial success. The line continually received processor, memory, hard disk upgrades, and new colors. FireWire and video out were later added.

[edit] Expandability/Upgrades

The original iBook's only customer-serviceable parts were the memory (RAM) and AirPort card, accessed via two slots under the easily-removable keyboard. No other modifications could be performed in warranty, and no PCMCIA port existed to provide additional expansion capabilities. Complicated procedures are required (such as removing nearly 40 screws) in order to access any internal components such as the hard disk and optical drive. Most iBooks shipped with Mac OS 8.6 or 9.0. Support for these iBooks is built into OS X v10.0 through v10.3.9. OS X v10.4 (Tiger) requires a Firewire port and DVD drive, essentially restricting it to the late-model iBook SE. iFixit offers a set of guides for the iBooks that provide instructions with pictures covering how to get to any internal component.^[2]

The third-party software XPostfacto^[3] enables installation of Mac OS X (10.0 and later) on unsupported Macs.

[edit] iBook G3 Dual USB (12.1-inch & 14.1-inch)

Processor(s):	PowerPC G3, 500–900 MHz

The next generation iBook G3 debuted at a press conference in Cupertino on May 1, 2001. The machine had been totally redesigned from scratch. Bold colors and the radical form-factor were abandoned for a white and slim-line polycarbonate shell, a design which earned Apple accolades from the computing industry and inspired the look of countless other products. The handle was removed, as was the latchless design. An L-shaped hinge reduced screen height, a feature Apple adopted in all its future portables.

With the iBook G3, Apple began its use of translucent and white polycarbonate in most of its consumer machines such as iMac, eMac, Mac Mini, MacBook. In contrast, most of its professional products used an anodized aluminum finish.

Developer:	Apple Computer
Released:	October 22, 2003
Discontinued:	May 16, 2006
Processor(s):	PowerPC G4, 800 MHz–1.42 GHz

A PowerPC G4 chip, slot-loading optical drives and a solid white case and keyboard were added on October 23, 2003—finally ending Apple’s use of the PowerPC G3 chip. The translucent case finish and magnesium components were replaced with opaque plastics. The iBook G4 is notable for lacking the translucent case finish, transluscent keyboard, magnesium chassis and palm rests, and magnesium display hinge (replaced with a plastic part) of the former iBook.

[edit] Expandability and upgrades

The iBook keyboard lifts up allowing installation of the AirPort (wireless) card and additional memory. This gives the keyboard a "spongy" effect, especially in PowerPC G3 models with the translucent keyboard. The "spongyness" was reduced in the later PowerPC G4 models.

However, accessing the hard drive is a complex and time-consuming procedure involving partial disassembly of the unit and the removal of over 20 screws, of many different types and length. iFixit offers a set of Fixit Guides for the iBooks that provide instructions with pictures covering how to get to any internal component.

Installing memory in the iBook G4 involves removing the keyboard, Airport (Wireless 802.11b/g) card and opening the RAM shield with a Phillips 00 screwdriver. While some of the lower models, eg. 800mhz and 933mhz G4 have specified a 640 MiB RAM limit, it may be possible to have a total of 1.5 GiB of RAM installed (512 MiB built-in, 1 GiB so-dimm add-on).

[edit] Quality issues

In late November 2003, a number of iBook G3 users started to report a display problem with their laptops. In December 2003, a group of users headed by Michael Johnson at http://www.blackcider.com/, and Bill Owen at http://www.eyestir.com/ sought to file a class action suit against Apple. In January 2004, in a response to the widely publicised display defect, Apple initiated the "iBook Logic Board Repair Extension Program", which covers any expense of repairing "affected iBooks for three years".^[4][5]

An online petition was started to encourage Apple to acknowledge that this problem is allegedly happening to early G4 iBook computers too, where one website has gathered nearly 2000 instances of logic board failure in the G4 iBooks shortly after the basic 1 year warranty.^[6][7] Also an increasing amount of users are reporting similar display problems with more recent 1 GHz models. In addition users are complaining on discussion boards across the web and on Apple's own site that the replacement logic boards are faulty and failing as well. An other online petition refers to this particular issue and has now collected over 4000 signatures^[8]. Apple has not admitted that these replacements are defective and new class action lawsuits have been submited Dec 2006.^[9] One discussion forum, guessing that some of the iBook problem was caused by the GPU losing contact, found that placing a shim between the plastic casing and the heat sink solved the problem - and that Apple was using this solution also. For a detailed explanation of the technique, see this guide.

[edit] Discontinuation

On May 16, 2006, the Intel-powered MacBook replaced the iBook line.
