Power management When you use your computer away from electrical outlets, you depend on battery power to keep your computer running. Different computer components consume power at different rates. The more you use the power-intensive components, the faster you consume battery power. Spend more time unplugged with ThinkPad batteries. Mobility has revolutionized business by enabling you to take your work wherever you go. With ThinkPad batteries, you will be able to work longer without being tied to an electrical outlet. 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 storage drive. - How bright you make the computer display. - How often you use the wireless features. To check for detailed battery status information, do the following: • For Windows 7: Open the Power Manager program and click the Battery tab. • For Windows 8.1: Open the Lenovo Settings program and click Power. Enabling the battery alarm on the Windows 7 operating system For the Windows 7 operating system, you can program your computer so that when the battery power falls below a certain level, three events occur: the alarm goes off, a message is displayed, and the LCD is turned off. To enable the battery alarm, do the following: 1. Start the Power Manager program. 2. Click the Global Power Settings tab. 38 User Guide
