power, but an internal power problem may exist.
–

Ensure the voltage selection switch is set to match the AC power at

your location, if applicable.

Ensure the processor power cable is securely connected to the system

• If the power light is steady amber, a device may be malfunctioning or

incorrectly installed.

Multiple power strips connected to the same electrical outlet

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. For example, beep code 1-3-1 (one possible beep code)

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.
Reseating the memory modules may correct the following beep code errors. If

the problem persists, contact Dell™ (see

obtaining technical assistance.
