Power/sleep lamp

also lets you know if the system is operating in a power-saving mode.
A steady green lamp indicates that the power is on to all system
components. An unlit lamp indicates that power is not on.
A steady amber lamp and a blank monitor (VESA-compliant) screen
indicates that the system is in a power-saving (sleep) mode, with
full-power reduction.

Hard drive lamp
A blinking lamp indicates that the hard drive is active. The blinking
lamp tells you that the hard drive is reading or writing data.
Do not turn off the system unless absolutely
necessary while the hard drive lamp is lit. To do so can damage your hard
drive or data.

also use the diskette drive as a bootable drive for loading and starting

To prevent damage to your diskette drive and
data, do not turn off the system or remove a diskette while the diskette
drive busy lamp is lit.
Universal Serial Bus Port

to easily and conveniently add plug and play USB devices without
opening up the system. You simply plug the USB device into the port.
You can connect up to 127 devices including a mouse, monitor, keyboard,
printer, scanner, speakers, and more. Two additional USB ports are on the
rear of the system.
