DIMM.

Power Button
The power button controls the system's AC input power.
The Microsoft® Windows® 98 and Windows 98 Second Edition (SE) operating systems let you configure the
function of the power button through the Advanced Configuration and Power Interface (ACPI) feature (see
Table 1).
NOTICE: To turn off your computer system, perform an orderly system shutdown using the operating
system menu when possible.
