Protecting Your Optical Drive

To keep your optical drive working properly:

ÂPosition your computer so that the drive tray doesn’t bump into anything when it opens.

ÂClose the drive when you’re not using it.

ÂDo not put anything on the drive tray when it is open.

ÂDo not touch the optical drive lens with your fingers. Do not wipe the lens with a paper towel or other abrasive surface. If you need to clean the lens, see an Apple Authorized Service Provider for a lens cleaner.

ÂKeep your computer away from any source of moisture.

Maintaining Your Display

To maintain your display and ensure its long life:

ÂDo not press on the surface of the display screen.

ÂDo not write on the screen or touch the screen with a sharp object.

ÂIf you will not be using your display and computer for a day or more, turn off the computer and display or use Energy Saver.

ÂTurn off your display, turn down the brightness, or use a screen saver program that dims or varies the image on the screen when the computer is idle for a prolonged time.

Important Ergonomic and Health-Related Information

Here are some guidelines for adjusting the furniture in your office to reduce glare and to accommodate your physical size and shape.

ÂAn adjustable chair that provides firm, comfortable support is best. Adjust the height of the chair so your thighs are tilted slightly and your feet are flat on the floor.

The back of the chair should support your lower back (lumbar region). Follow the manufacturer’s instructions for adjusting the backrest to fit your body properly.

ÂWhen you use the computer keyboard, your shoulders should be relaxed. Your upper arm and forearm should form an approximate right angle, with your wrist and hand in roughly a straight line.

You may have to raise your chair so your forearms and hands are at the proper angle to the keyboard. If this makes it impossible to rest your feet flat on the floor, you can use a footrest with adjustable height and tilt to make up for any gap between the floor and your feet. Or you can lower the desktop to eliminate the need for a footrest. Another option is to use a desk with a keyboard tray that’s lower than the regular work surface.

ÂPosition the mouse at the same height as your keyboard. Allow adequate space to use the mouse comfortably.

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.
