● Disposal of LCD
The fluorescent tube in the LCD contains mercury. When disposing of the PC, follow your local
environmental rules and regulations.
● Disposal of battery
Since batteries are used in the PC unit, an explosion may occur if it is thrown into a fire. When
disposing of an old battery, follow your local environmental rules and regulations.
■ Power-saving function (Windows 2000 models)

an internal option of peripheral (e.g. a printer or USB device) that does not support the advanced
power-saving mode, your PC may malfunction after returning from the standby mode.
In such cases, switch the standby mode from Advanced (ACPI S3) to Standard (ACPI SI).
■ USB (Windows 2000 models)
“USB” stands for “Universal Serial Bus”, which standardizes mouse, keyboard, printer, modem,
and speaker interfaces.
