The computer won’t turn on or start up.

ÂMake sure the power cord is connected to a working power source. The plug on the power cord must be completely inserted into the computer’s power socket and firmly seated for your computer to operate correctly.

ÂIf your computer still does not start, try resetting the parameter random access memory (PRAM). Turn on the computer and immediately hold down the Command (x), Option, P, and R keys until you hear the startup sound a second time. Release the keys. Set your hard disk as the computer’s startup disk, by doing the following:

1Choose Apple () > System Preferences

2Click Startup Disk

3Select your hard disk

The PRAM is reset to the default values and your clock settings may need to be reset.

ÂIf your computer does not start up after resetting the PRAM, restart your computer while holding down the Option key to select your startup system.

ÂIf this doesn't work, restart your computer while holding down the Shift key.

The status light flashes and the computer won’t start up.

ÂIf you recently installed additional memory, a PCI expansion card, or another internal component, make sure that it is correctly installed and that it is compatible with your computer. See if removing it allows the computer to start up.

ÂIf the status light still flashes, determine the number of flashes to identify the problem:

Â2 flashes: no RAM installed

Â3 flashes: incompatible RAM installed

Â4 flashes: no good DIMM banks

Â5 or 6 flashes: contact an Apple Authorized Service Provider

You are unable to eject a disc.

A file on the disc may be in use. Quit applications that are open, then try again.

If that doesn’t work:

1Shut down the computer.

2Carefully press down the front panel covering the front of the drive tray and locate the small hole below the drive tray.

3Carefully insert the end of a large straightened paper clip into the hole.

G5 specifications

The Apple G5, introduced in June 2003, marked a significant advancement in personal computing with its innovative architecture and powerful performance. It was the first desktop computer to feature a 64-bit architecture, which allowed it to process larger amounts of data more efficiently than its 32-bit predecessors. The G5 was equipped with the IBM PowerPC 970 processor, which operated at speeds ranging from 1.6 GHz to 2.7 GHz, making it a formidable contender in the market for both personal and professional use.

One of the standout features of the G5 was its aluminum chassis, which not only gave it a sleek and modern look but also aided in heat dissipation. The innovative design allowed the G5 to maintain lower operating temperatures regardless of the loads it handled. The G5 was famous for its quiet operation, thanks to a temperature-controlled, variable-speed fan system that minimized noise during regular use while still providing adequate cooling during intensive tasks.

In terms of memory, the G5 could support up to 8 GB of RAM, utilizing DDR SDRAM technology that provided enhanced performance in multitasking and complex applications. For graphics, the G5 offered powerful options, including dedicated GPU support from NVIDIA and ATI, enabling users to perform demanding tasks such as video editing and 3D graphics rendering with ease.

The connectivity options on the G5 were well thought out, including built-in USB 2.0 and FireWire 800 ports, which supported high-speed data transfer for external devices. In addition, the G5 featured an Ethernet port for networking capabilities, making it suitable for both home and office environments.

The G5 also ran on Mac OS X, which was optimized to take full advantage of its hardware capabilities. With its Unix-based foundation, Mac OS X provided users with a stable and secure operating environment, complete with a plethora of software applications tailored for creative professionals, including those in graphic design, video editing, and audio production.

Overall, the Apple G5 was a groundbreaking machine that successfully combined advanced technology, stylish design, and robust performance, earning a dedicated following among professionals and enthusiasts alike. Its legacy continues to influence Apple's approach to desktop computing, marking a pivotal moment in the evolution of personal computers.
