Checking the battery status
The battery-status icon in the Windows notification area displays the percentage of battery power remaining.
The rate at which you use battery power will determine how long you can use the battery of your computer
between charges. Because each computer user has different habits and needs, it is difficult to predict how
long a battery charge will last. There are two main factors:
• How much energy is stored in the battery when you begin to work.
• The way you use your computer. For example:
– How often you access the hard disk drive, solid-state drive, or hybrid drive.
– How bright you make the computer display.
– How often you use the wireless features.

• For Windows 7: Open the Power Manager program and click the Battery tab.
• For Windows 8 and Windows 8.1: Open the Lenovo Settings program and click Power.
