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
Notebooks, Mobile 
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 the power/sleep button 
is pressed.
If Wake-on-Lan (WOL) is 
enabled, the system can 
resume from sleep in 
response to a network signal.
Tablets/Slates
Less than or equal to 1 
minute
Not applicable
Not applicable
For computers that support an always-on, always-connected use profile where internet access is 
available (such as tablets and slates), alternative low power modes - such as Short or Long Idle 
modes (as defined in the ENERGY STAR Computer Program Requirements) are provided that 
consume very little power (</= 10 Watts) and when applicable, maximize product battery life. These 
alternative low power modes are dynamic, with the display sleep mode activated within 1 minute of 
user inactivity.
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.
