Notes:
1. Power consumption and heat output
vary depending on the number and type
of optional features installed and the
power-management optional features 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 values stated 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.
