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® Vista Home Premium 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.
