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.
