IBM Enhanced Diagnostics
The IBM Enhanced Diagnostics program runs independently of the operating
system. You can use this program to test the hardware components of your
computer. This method of testing is generally used when other methods are not
available or have not been successful in isolating a problem suspected to be
hardware related.
You can run the IBM Enhanced Diagnostics program using the Product Recovery
CD that comes with your computer.
Running the IBM Enhanced Diagnostics program
Use the following steps to run diagnostics from the Product Recovery CD.
1. Insert the Product Recovery CD into the CD-ROM.
2. Restart your computer. If your computer does not start from the CD, then you
need to change the startup sequence (for further information, see “Changing
the startup sequence” on page 32), and then restart your computer.
3. Wait for the main menu to open.
4. From the main menu, select System Utilities.
5. From the System Utilities menu, select Run Diagnostics. The IBM Enhanced
Diagnostics program starts.
6. When you finish running the diagnostics, remove the CD from the CD-ROM
drive and turn off the computer.
7. If you changed the First Startup Device in the Primary Startup Sequence, then
restore it to the original setting. See “Changing the startup sequence” on page
32.
Replacing the battery
Your computer has a special type of memory that maintains the date, time, and
settings for built-in features. A battery keeps this information active when you
turn off the computer.
The battery 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 no longer set. An error message is
displayed when you turn on the computer.
CAUTION:
Danger of explosion if battery is incorrectly replaced.
When replacing the battery, use only IBM Part Number 33F8354 or an
equivalent type battery recommended by the manufacturer. The battery
contains lithium and can explode if not properly used, handled, or disposed of.
