2.2 Basic Flowchart

The basic flowchart in Figure 2-1 serves as a guide for identifying a possibly faulty FRU.

Before going through the diagnostic flowchart steps, verify the following:

Ask the user if a password has been registered and, if so, ask him or her to enter the password. If the user has forgotten the system password, use a jump wire to make a short circuit on M/B B500 location, then turn the computer power on. When booted, the computer overrides password protection and automatically erases the current password.

Make sure the Windows® 7 Home Edition has been installed on the HDD. Any other operating system can cause the computer to malfunction.

Make sure any piece of optional equipment has been installed.
