Using the ac power adapter and the battery pack

This topic provides information about how to use the ac power adapter and the battery for your computer.

Checking the battery status

The battery gauge 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 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: how often you access the hard disk drive, how bright you make the computer display.

Chapter 2. Using your computer11

Using the ac power adapter

The power to run your computer can come either from the lithium-ionbattery pack provided with it, or from ac power through the ac power adapter. While you use ac power, the battery charges automatically.

The ac power adapter has two basic components:

1.The transformer pack that converts ac power adapter for use with the computer.

2.The power cord that plugs into the ac outlet and into the transformer pack.

Attention: Using an improper power cord could cause severe damage to the computer.

Connecting the ac power adapter

To connect the ac power adapter, do the following:

1.Connect the ac power adapter to the ac power connector of the computer.

2.Connect the power cord to the transformer pack.

3.Plug the power cord into an electrical outlet.

Tips on using the ac power adapter

When using the ac power adapter, observe the following guidelines:

When the ac power adapter is not in use, disconnect it from the electrical outlet.

Do not bind the power cord tightly around the ac power transformer pack when it is connected to the transformer.

Before you charge the battery, make sure that its temperature is at least 10°C (50°F).

You can charge the battery when the ac power adapter is connected to the computer and the battery is installed.

Charging the battery

When you find that the battery power is low, you need to charge the battery or replace it with a fully charged one.

You are recommended to charge the battery in any of the following situations:

When you purchase a new battery

If the battery status indicator starts blinking

If the battery has not been used for a long time

Notes:

You are advised to install the battery pack when using your computer to prevent small particles from entering the inside of your computer.

To maximize the battery life, do not start recharging the battery immediately after it drops from full charge.

Charge the battery at a temperature between 50 °F and 86 °F (10 °C-30°C).

Full charge or discharge is not required.

Maximizing the battery life

To maximize the life of a new battery or a battery that you have not used recently, do either of the following:

Use the battery until the charge is completely depleted; that is, use the battery until the battery status indicator starts blinking orange.

12 User Guide

Recharge the battery completely before using it. The battery is fully charged if the battery indicator shows green when the ac power adapter is plugged in.

Handling the battery

DANGER

Do not attempt to disassemble or modify the battery pack.

Attempting to do so can cause an explosion, or liquid leakage from the battery pack.

A battery pack other than the one specified by Lenovo, or a disassembled or modified battery pack is not covered by the warranty.

DANGER

If the rechargeable battery pack is incorrectly replaced, there is danger of an explosion. The battery pack contains a small amount of harmful substances. To avoid possible injury:

This chapter provides information about accessibility and comfort.

Accessibility and comfort

Good ergonomic practice is important to get the most from your personal computer and to avoid discomfort. Arrange your workplace and the equipment you use to suit your individual needs and the kind of work

that you perform. In addition, use healthy work habits to maximize your performance and comfort while using your computer.

The following topics provide information about arranging your work area, setting up your computer equipment, and establishing healthy work habits.

Lenovo is committed to providing the latest information and technology to our customers with disabilities. Refer to our accessibility information which outlines our efforts in this area.

Ergonomic information

Working in the virtual office might mean adapting to frequent changes in your environment. Following some simple rules will make things easier and bring you the maximum benefits of your computer. Keeping in mind such basics as good lighting and proper seating, for example, can help you improve your performance and achieve greater comfort.

This example shows someone in a conventional setting. Even when not in such a setting, you can follow many of these tips. Develop good habits, and they will serve you well.

General posture: Make minor modifications in your working posture to deter the onset of discomfort caused by long periods of working in the same position. Frequent, short breaks from your work also help to prevent minor discomfort associated with your working posture.

Display: Position the display to maintain a comfortable viewing distance of510-760mm(20-30inch). Avoid glare or reflections on the display from overhead lighting or outside sources of light. Keep the display screen
