---|---|---|
Solid green | Power is on, and the computer is operating normally. On the desktop computer, a solid green light indicates a network connection. | No corrective action is required. |
Blinking green | The computer is in a power-saving mode (Microsoft® Windows® XP). | Press the power button, move the mouse, or press a key on the keyboard to wake the computer. |
Blinks green several times and then turns off | A configuration error exists. | Check the diagnostic lights to see if the specific problem is identified (see Diagnostic Lights). |
Solid yellow | The Dell Diagnostics is running a test, or a device on the system board may be faulty or incorrectly installed. | If the Dell Diagnostics is running, allow the testing to complete. If the computer does not boot, contact Dell for technical assistance (see Contacting Dell). |
Blinking yellow | A power supply or system board failure has occurred. | See Power Problems. |
Solid green and a beep code during POST | A problem was detected while the BIOS was executing. | See Beep Codes for instructions on diagnosing the beep code. Also, check the diagnostic lights to see if the specific problem is identified (see Diagnostic Lights). |
Solid green power light and no beep code and no video during POST | The monitor or the graphics card may be faulty or incorrectly installed. | Check the diagnostic lights to see if the specific problem is identified (see Diagnostic Lights). See Video and Monitor Problems. |
Solid green power light and no beep code but the computer locks up during POST | An integrated system board device may be faulty. | Check the diagnostic lights to see if the specific problem is identified (see Diagnostic Lights). If the problem is not identified, contact Dell for technical assistance (see Contacting Dell). |
Diagnostic Lights
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide. |
If the POST portion of system boot completes successfully, all four lights display solid green. If the computer malfunctions during the POST process, the pattern displayed on the LEDs may help identify where in the process the computer halted.
NOTE: The orientation of the diagnostic lights may vary dependent upon the computer type. The diagnostic lights can appear either vertical or horizontal. |

Suggested Resolution

---|---|---|
| The computer is in a normal "off" condition, or a possible pre-BIOS failure has occurred. The diagnostic lights are not lit after the computer successfully boots to the operating system. | Plug the computer into a working electrical outlet and press the power button. |
| A possible BIOS failure has occurred; the computer is in the recovery mode. | Run the BIOS Recovery utility, wait for recovery completion, and then restart the computer. |
| A possible processor failure has occurred. | Reinstall the processor and restart the computer. |
| Memory modules are detected, but a memory failure has occurred. |
|
| A possible graphics card failure has occurred. |
|
| A possible floppy or hard drive failure has occurred. | Reseat all power and data cables and restart the computer. |
| A possible USB failure has occurred. | Reinstall all USB devices, check cable connections, and then restart the computer. |
| No memory modules are detected. |
|
| Memory modules are detected, but a memory configuration or compatibility error exists. |
|
| A failure has occurred. This pattern also displays when you enter system setup (see Entering System Setup) and may not indicate a problem. |
|
| After POST is complete, all four diagnostic lights turn green briefly before turning off to indicate normal operating condition. | None. |
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:
- Write down the beep code on the Diagnostics Checklist.
- Run the Dell Diagnostics to identify a more serious cause (see Dell Diagnostics).
- Contact Dell for technical assistance (see Contacting Dell).
