Your computer batteries
Your computer batteries enable you to do more, save more, and spend more time
unplugged. Mobility has revolutionized business by enabling you to take your work
wherever you go. With your computer batteries, you will be able to work longer
without being tied to an electrical outlet.
Note:
The operating system may run slower when using the battery mode.
DANGER
Use only the original battery or a battery supplied by Lenovo. The use of any other battery
gives rise to a risk of fire. Dispose of used batteries in accordance with the instructions.
Checking battery status
You can determine the percentage of battery power remaining by using Windows
Power options.
The rate at which you use battery power determines how long you can use the
battery of your computer between charges. As 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:
v The amount of energy stored in the battery when you begin to work.
v The way you use your computer: for example, how often you access the hard disk
drive and how bright you make the computer display.
