Handling static-sensitive devices

Do not open the static-protective package containing the new part until the defective part has been removed from the computer and you are ready to install the new part. Static electricity, although harmless to you, can seriously damage computer components and parts.

When you handle parts and other computer components, take these precautions to avoid static-electricity damage:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Always handle parts and other computer components carefully. Handle

adapters, memory modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.

v Prevent others from touching the parts and other computer components.

v Before you replace a new part, touch the static-protective package containing the

part to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. This reduces static electricity in the package and your body.

v When possible, remove the new part from the static-protective packaging, and

install it directly in the computer without setting the part down. When this is not possible, place the static-protective package that the part came in on a smooth, level surface and place the part on it.

v Do not place the part on the computer cover or other metal surface.

Replacing the battery

Your computer has a special type of memory that maintains the date, time, and settings for built-in features, such as parallel-port assignments (configuration). A battery keeps this information active when you turn off the computer.

The battery normally requires no charging or maintenance throughout its life; however, no battery lasts forever. If the battery fails, the date, time, and configuration information (including passwords) are lost. An error message is displayed when you turn on the computer.

Refer to the "Lithium battery notice" in the Safety and Warranty Guide for information about replacing and disposing of the battery.

To replace the battery:

1. Remove the computer cover. See “Removing the cover” on page 12.

2. Locate the battery. See “Identifying parts on the system board” on page 9.

3. Remove the old battery.

Figure 17. Battery removal

24 Hardware Installation and Replacement Guide

4. Install the new battery.

Figure 18. Battery installation

5. Replace the computer cover, and connect the cables. See Chapter 4, “Completing the parts replacement,” on page 47.

Note: When the computer is turned on for the first time after battery replacement, an error message might be displayed. This is normal after replacing the battery.

6. Turn on the computer and all attached devices.

7. Use the Setup Utility program to set the date and time and any passwords. See

"Using the Setup Utility" in the User Guide.

Chapter 5. Security features

To help prevent hardware theft and unauthorized access to your computer, several security lock options are available. In addition to a physical lock, unauthorized use of your computer can be prevented by a software lock that locks the keyboard until a correct password is typed in.

Make sure that any security cables that you install do not interfere with other computer cables.

Integrated cable lock

An integrated cable lock (sometimes referred to as the Kensington lock), can be used to secure your computer to a desk, table, or other non-permanent fixture. The cable lock attaches to a security slot at the rear of your computer and is operated with a key. See Figure 43. The cable lock also locks the buttons used to open the computer cover. This is the same type of lock used with many laptop computers. You can order a security cable directly from Lenovo. Go to http://www.lenovo.com/support/ and search on Kensington.

Figure 43. Integrated cable lock

Padlock

Your computer is equipped with a padlock loop such that the cover cannot be removed when a padlock is installed.

Figure 44. Installing a padlock

Password protection

To deter unauthorized use of your computer, you can use the Setup Utility program to set a password. When you turn on your computer, you are prompted to type the password to unlock the keyboard for normal use.

What to do next:
