Power Problems

The power light on the front panel communicates codes that can help you determine whether there is a problem with your computer. The following table lists the codes for the power light. For more information, see "Diagnostic Lights."

Power Light Codes 

Power Light	Cause
Solid green	Power is on, and the computer is operating normally.
Blinking green	The computer is in the sleep state (Microsoft® Windows® 2000 and Windows XP). For more information, see "Power Management."
Blinks green several times and then turns off	There is a configuration error. Check the diagnostic lights to see if the specific problem is identified.
Solid yellow	The Dell Diagnostics is running a test, or a device on the system board may be faulty or incorrectly installed.
Blinking yellow	There is a system board or power supply failure.

Basic Checks:

• Check the diagnostic lights to see if the specific problem is identified.
  
  
• Test the electrical outlet: ensure that the electrical outlet is working by testing it with a different device such as a lamp.
  
  
• While diagnosing the problem, connect the computer power cable directly to a known working electrical outlet to ensure that the computer turns on. Do not connect it to a power protection device, UPS, power strip, or extension cord.
  
  
• Ensure that all power cables are firmly connected, verifying that each power cable is adequately connected at the computer device and to the electrical outlet.
  
  
• Check for interference: electrical appliances on the same circuit or operating in close proximity to the computer can cause interference.
  
  
• Test the power cable: swap the power cables between the computer and the monitor to see whether the problem symptoms change.
  
  

If the problem still exists after you complete the basic checks, fill out the Diagnostics Checklist as you perform the following steps:

1. Turn off the computer and devices, disconnect them from their electrical outlets, and wait 10 to 20 seconds.
   
   
2. Reconnect the computer and devices to their electrical outlets.

• Remove any newly added hardware and contact the hardware manufacturer.
  
  
• See your OS documentation.
  
  

System Memory Problems

During POST, the computer checks the computer's memory, determines the amount of installed memory, and then writes to and reads from the number of available bytes to ensure proper operation.

NOTE: If you installed up to 4 GB of memory but not all of it is available for use by the OS, see "Addressing Memory with 4-GB Configurations."

Basic Checks:

• Check the diagnostic lights to see if the specific problem is identified.
  
  
• If an insufficient memory message appears, save and close any open files and exit any open application programs not in use. Consider installing additional system memory.
  
  
• Restart the computer.
  
  
• Run the System Memory test group in the Dell Diagnostics.
  
  
• If you have the optional memory riser boards installed, reseat the riser boards.
  
  
• Reseat the memory modules in system board or riser board sockets.
  
  
• If you are not using the optional memory riser boards, verify that all system board memory sockets contain a RIMM or CRIMM.
  
  
• Memory modules must be installed in matched pairs. Ensure that the modules installed in system board or memory riser board socket pairs are identical. To identify system board socket pairs, see "System Board Memory Components." To identify memory riser board socket pairs, see "Memory Riser Board Components."
  
  

If the problem still exists after you complete the basic checks, fill out the Diagnostics Checklist as you perform the following steps.

CAUTION: Before you perform this procedure, see "Safety First— For You and Your Computer."
