Using The Ac Adapter - Lenovo 06472AU User Manual

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.

Using the AC adapter

The power to run your computer can come either from the lithium-ion (Li-ion)
battery pack provided with it, or from AC power through the AC adapter. While you
use AC power, the battery charges automatically.
The AC adapter that comes with your computer has two basic components:
1. The transformer pack that converts AC power for use with the computer.
2. The power cord that plugs into the AC outlet and into the transformer pack.
CAUTION
Using an improper power cord could cause severe damage to your computer.
To use the AC adapter, do the following. Be sure to take these steps in the order in
which they are given here.
1. Connect the AC adapter to the AC power adapter jack of the computer.
2. Connect the power cord to the transformer pack.
