Lenovo encourages you to make efficient use of energy an integral part of your day-to-day operations. To
help in this endeavor, Lenovo has preset the following power-management features to take effect when your
computer has been inactive for a specified length of time:
Power plan: Default

settings, see the Windows help information on the computer.

setting remains valid even when the computer is in sleep mode. If you do not need to have Wake on LAN
enabled while the computer is in sleep mode, you can reduce the power consumption and prolong the time
in sleep mode, by disabling the setting of Wake on LAN for sleep mode.
