CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in the
Product Information Guide.
•Turn on your printer if one is attached.
•Enter system setup, review your computer’s configuration information, and enable all of your
computer’s components and devices, such as connectors.
Beep Codes
Your computer might emit a series of beeps during start-up if the monitor cannot display errors or problems.
This series of beeps, called a beep code, identifies a problem. One possible beep code (code 1-3-1)
consists of one beep, a burst of three beeps, and then one beep. This beep code tells you that the
computer encountered a memory problem.
If your computer beeps during start-up:

To help you troubleshoot a problem, your computer has four lights labeled "1," "2," "3," and "4" on the
front. The lights can be "off" or green. When the computer starts normally, the lights flash. If the
computer malfunctions, the pattern of the lights and also that of the power button help to identify the
problem.These lights also indicate sleep states.

Frequently Asked Questions
How Do I...SolutionWhere to Find Additional Information
Set up my computer to use
two monitors?
Connect my monitor when the
monitor cable connector doesn’t
seem to fit the connector on the
back of my computer?
If your computer has the required
graphics card to support dual-monitor
setup, then look in your shipping box
for a Y-cable. The Y-cable has a single
connector on one end (plug this
connector into the back panel) and
branches into two connectors
(plug these connectors into the
monitor cables).
If your graphics card has a DVI
connector but your monitor has a VGA
connector, then you need to use an
adapter. An adapter should be included
in the shipping box.
