Your system performs a power-on self-test (POST) when it starts.  Should
you encounter any of the following problems, follow the corresponding
instructions:

Your computer does not come on:

     Are all the cables properly connected to the computer?  If you
     are using a printer or other device with your computer, make sure
     it is properly connected and turned on.  (See the device's manual
     for instructions.)

     If you have installed an add-in board, have you installed it
     correctly?

     Is the voltage setting on the back panel set to 115V, or 230 V if
     your power outlet uses that voltage?

The computer comes on, but nothing appears on the monitor:

     Is the monitor plugged in and turned on?  Are the brightness
     and contrast nobs correctly adjusted?

     Is your software correctly configured for your monitor and video
     adapter?  Check the software user's manual.

     If you installed an add-in video board, have you installed and
     configured it correctly?

The computer comes on, but does not finish booting:

     Does the computer beep more than once when you turn it on?
     If you just changed the computer configuration, it may not be
     configured correctly.  Run System Setup to fix the configuration
     The section "POST Beep Codes" can help you determine which
     component caused the error.

     Does a configuration error message appear on the screen?  If so,
     run System Setup to correct the problem.

     If you installed a second hard drive, have you installed and
     configured it correctly?  Check your installation and make sure
     it is correct.

     Does the computer report a CMOS or battery failure error?  Run
     System Setup to check your configuration.  If the configuration
     settings are lost, the batter needs to be replaced.

The computer boots but does not run properly:

     Is the computer unable to use the second hard disk you installed?
     Make sure it is configured in System Setup.  Also, make sure you
     have partitioned and formatted the drive.

You have problems using a CD-ROM drive:

     Make sure you are using the appropriate version of the MSCDEX.EXE 
     CD-driver software.  Use the version of MSCDEX.EXE that came with
     your operating system, or contact the manufacturer of the CD-ROM
     drive for the correct CD-driver software.
