Handling The Battery - Lenovo ThinkPad E450 User Manual

• Hibernation mode
By using this mode, you can turn off your computer completely without saving files or exiting any
programs that are running. When the computer enters hibernation mode, all open programs, folders, and
files are saved to the hard disk drive, hybrid drive, or solid-state drive, and then the computer turns off.
To put the computer into hibernation mode, do the following:
– For Windows 7: Open the Start menu, then click the arrow next to the Shut down button. Click
Hibernate from the menu displayed.
– For Windows 8.1: Define what the power button does first, then press the power button to put the
computer into hibernation mode. For more information, see Front view.
If you put your computer into hibernation mode with the wake-up function disabled, the computer does
not consume any power. The wake-up function is disabled by default. If you put your computer into
hibernation mode with the wake-up function enabled, the computer consumes a small amount of power.
To enable the wake-up function, do the following:
1. Go to Control Panel and click System and Security.
2. Click Administrative Tools.
3. Click Task Scheduler. If you are prompted for an administrator password or confirmation, type the
password or provide confirmation.
4. From the left pane, select the task folder for which you want to enable the wake-up function. The
scheduled tasks are displayed.
5. Click a scheduled task, and then click the Conditions tab.
6. Under Power, select the check box for Wake the computer to run this task.
To put the computer into hibernation mode, change your power plan settings by doing the following:
– For Windows 7: Start the Power Manager program and then click the Power Plan tab. Then follow
the instructions on the screen. For instructions on how to start the Power Manager program, see
"Accessing Lenovo programs on the Windows 7 operating system" on page 12.
– For Windows 8.1: Go to the desktop. Right-click the battery status icon in the Windows notification
area and click Power Options, click Change plan settings that is next to your power plan. Then
follow the instructions on the screen.
