Turning on the computer

When the computer is connected to an ac power source but is not turned on, the
operating system does not run, and all core logic is shut down; however, the
computer can respond to remote requests to turn on the computer. The power-on
LED flashes to indicate that the computer is connected to an ac power source but is
not turned on (standby mode).

the rear of the computer.
When this LED is lit, it indicates that there is an active connection on the
Ethernet port. This LED is located on the rear of the computer.
When this LED is lit, it indicates that the hard disk drive is in use.
Use these connectors (four-pin on the front and six-pin on the rear) to
connect IEEE 1394 devices, such as digital video cameras and external
hard disk drives.
Note: Some models come with the IEEE 1394 adapter installed. If your
computer did not come with this adapter installed, do not install any
adapter in the mini-PCI slot. It is not supported.
Use this connector to send audio signals from the computer to external
devices, such as speakers with built-in amplifiers, headphones, multimedia
keyboards, or the audio line-in jack on a stereo system.
Use this connector to connect a microphone to your computer when you
want to record voices or other sounds on the hard disk. You can also use
this connector (and a microphone) with speech recognition software.
Press this button to turn the computer on or off.
When this LED is lit and not flashing, it indicates that the computer is
turned on. When this LED is flashing, it indicates that the computer is off
and still connected to an ac power source (standby mode).
When this amber LED is lit, it indicates that a system error has occurred.
An LED on the system board is also lit to help isolate the error.
Use these connectors to connect USB devices to your computer, using
redundant Plug and Play technology.
