nergy Star Compliance
Certain configurations of Dell computer systems comply
with the requirements set forth by the Environmental
Protection Agency (EPA) for energy-efficient computers.
If the front panel of your computer bears the Energy Star
Emblem (see Figure 1-4), your original configuration
complied with these requirements and all Energy Star
power management features of the computer are enabled.
NOTES: As an Energy Star Partner, Dell Computer Cor-
poration has determined that these products meet the
Energy Star guidelines for energy efficiency.
Any Dell computer bearing the Energy Star Emblem is
certified to comply with EPA Energy Star requirements
as configured when shipped by Dell. Any changes you
make to this configuration may increase the system's
power consumption beyond the limits set by the EPA's
Energy Star Computers program.
