Putting the Computer to Sleep to Save Energy

Power Mac G5 computers are set to go to sleep after a period of inactivity. Sleep is a state in which your computer uses very little power. You can also put the computer to sleep whenever you want to.

Note: Power Mac G5 computers are set to sleep automatically within15 minutes of inactivity; however, you can change the automatic sleep settings in System Preferences.

When the computer wakes from sleep, your programs, documents, and computer settings are exactly as you left them. To save more energy, shut down the computer when it’s not in use.

To put your computer to sleep, you can do any of the following:

Press the power button on the front of the computer.

Choose Apple (K) > Sleep.

Choose Apple (K) > System Preferences, click Energy Saver, and set a sleep timer.

When the computer is in sleep, the front panel power button light pulses.

To wake the computer, press the power button on the front of the computer or press a key on the keyboard. With some Apple displays, you can also use the display’s power button to put the computer to sleep and wake it.

Not all PCI cards or replacement AGP cards comply with the computer’s power management standards. If you install a noncompliant card, the computer can still enter sleep mode, but it may not save as much energy as possible.

For more information about energy-saving options, see Mac OS Help.

Transferring Information Between Two

Macintosh Computers

If two Macintosh computers are not connected by an Ethernet, AirPort, or Bluetooth network, you can transfer information between them by connecting them with a standard Cat 5 Ethernet cable (in effect creating a small network of just two computers). You can buy this type of cable from an Apple Authorized Reseller. You connect the cable to each computer’s Ethernet port and then turn on file sharing on both computers. You can also configure the Ethernet settings on two computers to create a small network.

First, turn on file sharing on both computers:

1Choose Apple (K) > System Preferences.

2Click Sharing, then click Start.

3Open Network preferences, select AppleTalk, and then select “Make AppleTalk Active.”

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.
