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.
