ENERGY STAR
®
Program
Your Computer model may be ENERGY STAR
®
compliant. If the model you purchased is compliant, it is
labeled with the ENERGY STAR logo on the computer and
the following information applies.
TOSHIBA is a partner in the ENERGY STAR Program and
has designed this computer to meet the latest ENERGY
STAR guidelines for energy efficiency. Your computer
ships with the power management options preset to a
configuration that will provide the most stable operating
environment and optimum system performance for both
AC power and battery modes.
To conserve energy, your computer is set to enter the low-
power Sleep Mode which shuts down the system and
display within 15 minutes of inactivity in AC power mode.
TOSHIBA recommends that you leave this and other
energy saving features active, so that your computer will
operate at its maximum energy efficiency. You can wake
the computer from Sleep Mode by pressing the power
button.
Products that earn the ENERGY STAR prevent
greenhouse gas emissions by meeting strict energy
efficiency guidelines set by the US EPA and the EU
Commission. According to the EPA, a computer meeting
the new ENERGY STAR specifications will use between
20% and 50% less energy depending on how it is used.
