Charging the battery
It is recommended that you charge the battery or replace it with a charged battery on any of the following
conditions:
• The percentage of battery power remaining is low.
• The power alarm alerts you that the remaining power is low.
Maximizing the battery life
To maximize the battery life, do the following:
• Use the battery until the charge is depleted; that is, use the battery until the battery status indicator starts
blinking orange.
• Fully recharge the battery before using it. The battery is fully charged if the battery indicator shows solid
green when the ac power adapter is plugged in.
• Always use power management features such as power modes, sleep, and hibernation.
Power-saving modes
There are several modes that you can use at any time to conserve power. This topic introduces each mode and
gives tips on the effective use of the battery power.
Sleep mode
If you are not going to use the computer for a short time, put the computer into sleep mode. When the
computer is in sleep mode, you can wake it up to resume use and bypass the startup process.
To put the computer into sleep mode, do the following:
• Windows 7:
1. Click Start.
2. Click the triangle mark next to the Shut down icon, and then select Sleep.
Windows 8:
1. Move the cursor to the top-right or bottom-right corner of the screen to display the charms.
2. Click Settings.
3. Select Sleep from the Power menu options.
• Press Fn + F1.
Attention: Wait until the power indicator starts blinking (indicating that the computer is in sleep state)
before you move the computer. Moving the computer while the hard disk drive is spinning can damage the
hard disk drive, causing loss of data.
To wake up the computer, do one of the following:
• Press the power button.
• Press the Fn key on the keyboard.
Hibernation mode
By using this mode, you can turn off the computer completely without saving files or exiting from any
program that is running. When the computer enters hibernation mode, all open programs, folders, and files
are saved to the hard disk drive, and then the computer turns off.
