Using a BIOS Floppy Disk 
If you do not have a BIOS floppy disk, download the package from the Partnership Web site (see page 
vi) under Product Support Information in the Service and Support Library. Follow the instructions for 
creating the BIOS floppy disk. 
 
Caution 
Make sure to use the correct BIOS floppy disk for the notebook model you are repairing. The 
program does not verify the notebook model, so you could accidentally install the wrong BIOS. 
 
1. 
2. 
Insert the BIOS floppy disk in the floppy disk drive. 
Turn on the notebook and allow it to boot from the BIOS floppy disk. 
 If the notebook does not turn on at all, do the following to boot from the BIOS floppy disk: 
 
a. Unplug the AC adapter. 
 b. Press and hold Fn+B 
 c. Plug in the AC adapter. 
 d. Release Fn+B. 
Note: If the notebook will not boot from the BIOS floppy disk, try plugging the boot-block jumper 
into the notebook’s parallel port. See the wiring diagram below. 
3. The display goes blank for a minute or more while the BIOS is reprogrammed. 
Note: If you plugged in a boot block jumper, unplug it before the notebook automatically reboots. 
4. After the BIOS reprograms itself, check the BIOS version to make sure it is the latest version. 
If necessary, download the latest BIOS version and reprogram the BIOS IC.

Troubleshooting and Diagnostics 
This chapter includes troubleshooting and diagnostic information for testing the functionality of the 
notebook, and for identifying faulty components: 
• ASP support information 
• Troubleshooting information 
! Checking for customer abuse (page 3-3). 
! Troubleshooting the problem (page 3-3). 
! Verifying the repair (page 3-4). 
! Suggestions for troubleshooting (page 3-5). 
• Diagnostic tools 
! e-Diagtools diagnostic program (page 3-18). 
! Power-on self-test (page 3-19). 
! Sycard PCCtest 450/460 PC card (page 3-25). 
! Windows Management Instrumentation (page 3-26). 
! BIOS Setup utility (page 3-26). 
Support by Authorized Service Providers 
In the U.S., support of notebook computers by Authorized Service Providers (ASPs) is a purchasable 
option. Standard predefined models and standard special models do not include ASP support. The sales 
force has the option of creating models with ASP support using the specials process. 
The serial number label on the bottom of the notebook indicates the ASP support status for that model. 
See the following table. 
Table 3-1. ASP Support Options 
Serial Number Label ASP Support Status 
“NoASP” No reimbursement to ASP for parts or labor. However the ASP is authorized to 
repair the notebook, and reimbursement can be negotiated directly with the 
customer. 
“ASP” Parts and labor will be reimbursed to the ASP. 
 
In other countries, ASP support is standard in most situations—but you should check the marking on 
the serial number label to verify the ASP support status for that model.

Troubleshooting 
The suggestions in this section can help isolate and repair the cause of a problem. To ensure quality 
repair, follow the basic troubleshooting steps shown below. 
  
 
Check the customer’s description
of the problem and any supporting
information.
Try to duplicate the customer’s
problem.
Troubleshoot the problem using:
  - Diagnostic tools.
  - Troubleshooting suggestions.
Verify the repair by testing the
functionality of the complete unit.
Check for customer abuse.

3-2 Troubleshooting and Diagnostics Service Manual  
						

							 
Checking for Customer Abuse 
Some notebooks might appear to have been damaged by customer abuse. Use these guidelines to help 
determine if this is the case: 
• If the shipping box is seriously damaged, customer abuse cannot be declared. 
• If the damage could have a cause other than customer abuse, customer abuse cannot be declared. 
• If the notebook shows any of the following, customer abuse is declared: 
! Missing parts. 
! Broken plastic parts. 
! Parts not original to the notebook. 
! Damaged or missing keys on the keyboard. 
Table 3-3 lists additional criteria for determining customer abuse to specific parts of the notebook. 
 
Important 
Parts damaged by customer abuse are not covered by the warranty. 
 
Troubleshooting the Problem 
Record pertinent information about the notebook: 
• Model and serial number. 
• Operating system and version. 
• Software version (stored in hidden file c:\version.inf). 
• BIOS version. 
• Accessories and peripherals used. 
Analyze the problem: 
• Observe Symptoms. Using the customer’s information, try to duplicate the problem. Determine 
how the problem differs from proper behavior. Also, note the functions that do work properly. 
• Separate Problems. If there are multiple symptoms, separate them into distinct problems. 
• Consider Causes. Keep in mind possible causes for each problem. Use the diagnostic tools and 
troubleshooting suggestions to help find possible causes. 
! The e-Diagtools diagnostic program tests most of the notebook’s components using automatic 
and interactive tests, and is your primary troubleshooting tool. Other tools include the  
power-on self-test, WMI/Toptools (if installed), the BIOS Setup utility, and the Sycard 
PCCtest. Table 3-2 on page 3-5 shows how you can use these tools to isolate the cause of the 
notebook’s problem. 
! The troubleshooting suggestions on page 3-6 include general suggestions for repairing 
notebooks that show specific failure symptoms. 
Service Manual Troubleshooting and Diagnostics 3-3  
						

							 
Swapping modules that might be defective with others known to be good is generally an ideal way to 
find the module responsible for the problem. A failure symptom is rarely caused by more than one 
module, so you will not usually need to replace more than one to correct a particular failure. 
After you replace a module, the notebook will normally be in a confused state and lock up when you 
apply power. If this happens, press the reset button: this turns the notebook off, so that you can restart 
it in a known state. 
Verifying the Repair 
Before returning the repaired notebook to the customer, verify the repair by running the following 
tests: 
• e-Diagtools Basic Diagnostic Test. Run the basic test of the e-Diagtools diagnostic program 
(page 3-18). 
 –and– 
• Function Tests. Run tests that check the repaired function, such as those in e-Diagtool\
s 
(page 3-18). 
 –and– 
• Failed Tests. Run any other tests that failed during troubleshooting.
