Lenovo S10 manual Using the AC adapter

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:

vThe amount of energy stored in the battery when you begin to work.

vThe 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.
