Tips for Troubleshooting
In each problem-specific section, try the steps in the order suggested. This may 
help you to solve the problem more quickly.
Try to pin point the problem and thus avoid replacing non-defective parts. 
Keep a record of the steps you take when troubleshooting: The information 
may be useful when calling for technical support or for passing on to service 
personnel.
Use some other electrical device to confirm that the electrical outlet is 
working.
Ensure the VM is turned on.
Ensure all connections are securely attached. 
The Power-On Self Test
The Power-On Self Test (POST) runs every time you turn on or reset the com-
puter. The POST checks memory, the mainboard, the display, the keyboard, 
the disk drives, and other installed options. 
A few seconds after you turn on your computer, a copyright message appears 
on your display screen. A memory test message appears next; as the test con-
tinues, memory size increases until all installed memory is tested. Normally, the 
only test routine visible on the screen will be the memory test.
If failure is detected in an area other than the mainboard (such as the keyboard 
or an adapter card), an error message is displayed on the screen and testing is 
stopped.
If your system does not successfully complete the POST, but displays a blank 
screen, emits a series of beeps, or displays an error code, consult your dealer.
