Putting the Computer to Sleep to Save Energy
Power Mac G4 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.
Note: Power Mac G4 computers are automatically set to sleep after 20 minutes of inactivity.
When the computer goes to sleep, it saves its state so that when you wake the computer,
your programs, documents, and computer settings are exactly as you left them. To save more
energy, shut down the computer or turn off the power strip when the computer is not in use.
To put your computer to sleep, you can do any of the following:
m Press the power button on the front of the computer.
m Choose Sleep from the Apple (K) menu.
m Set a sleep timer in your computer’s sleep settings by choosing System Preferences from
the Apple (K) menu and clicking Energy Saver.
When the computer is in sleep, the front panel power button light pulses.
To wake the computer, press the power button on the front panel of the computer, or press a
key on the keyboard. With some Apple monitors, you can also use the monitor’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 non-compliant card, the computer can still enter sleep mode, but it
will not achieve maximum energy saving. You can use the Apple System Profiler to find out
whether an installed card is compliant.
