ENERGY STAR
®
Certification (select models only)
ENERGY STAR is a U.S. Environmental Protection Agency voluntary program that helps businesses
and individuals save money and protect our climate through superior energy efficiency. Products that
earn the ENERGY STAR prevent greenhouse gas emissions by meeting strict energy efficiency
criteria or requirements set by the U.S. Environmental Protection Agency. As an ENERGY STAR
Partner, Hewlett-Packard Company has followed the U.S. EPA’s enhanced product certification
process to ensure that products marked with the ENERGY STAR logo are ENERGY STAR certified
per the applicable ENERGY STAR guidelines. The following logo appears on all ENERGY STAR-
certified computers::
A key ENERGY STAR requirement for computer products is power management features that
significantly reduce energy consumption when the product is not in use. Power management allows a
computer to automatically enter a low power “sleep” mode, or other low power mode, after a defined
period of inactivity. The power management features have been preset as follows when the computer
is operating on AC power:
Computer type Time to activate display
sleep mode
Time to activate computer
sleep mode (minutes)
Resuming from sleep mode
Desktops, Integrated
Desktops, Workstations
Less than or equal to 15
minutes (varies by model)
Less than or equal to 30
minutes (varies by model)
Product will exit sleep mode
when user interacts with any
input device, including the
mouse or keyboard.
If Wake-on-Lan (WOL) is
enabled, the system can
resume from sleep in
response to a network signal.
Thin clients Less than or equal to 15
minutes (varies by model)
Less than or equal to 30
minutes when sleep mode is
supported by the operating
system (varies by model)
When sleep mode is
supported by operating
system product will exit sleep
mode when user interacts
with any input device,
including the mouse or
keyboard.
If Wake-on-Lan (WOL) is
enabled, the system can
resume from sleep in
response to a network signal.
The computer exits Sleep when the power/Sleep button is pressed. When the Wake On LAN (WOL)
feature is enabled, the computer can also exit Sleep in response to a network signal.
