Notes:
1. Power consumption and heat output
vary depending on the number and type
of optional features that are installed and
the power-management optional features
that are in use.
2. These levels were measured in
controlled acoustical environments
according to the procedures specified by
the American National Standards
Institute (ANSI) S12.10 and ISO 7779
and are reported in accordance with ISO
9296. Actual sound-pressure levels in a
given location might exceed the average
stated values because of room
reflections and other nearby noise
sources. The declared sound-power
levels indicate an upper limit, below
which a large number of computers will
operate.
