Troubleshooting

Dell SupportAssist Pre-boot System Performance Check  diagnostics

About this task
SupportAssist diagnostics (also known as system diagnostics) performs a complete check of your hardware. The Dell SupportAssist Pre-boot System Performance Check diagnostics are embedded within the BIOS and launched by the BIOS internally. The embedded system diagnostics provides options for particular devices or device groups,, allowing you to:

• Run tests automatically or in an interactive mode.
• Repeat the tests.
• Display or save test results.
• Run thorough tests to add more options and obtain details about any failed devices.
• View status messages that inform you when the tests are completed successfully.
• View error messages that inform you of problems encountered during testing.

NOTE: Some tests for specific devices require user interaction. Always ensure that you are present at the computer when the diagnostic tests are performed.

For more information, see the knowledge base article 000181163.

Running the SupportAssist Pre-Boot System Performance Check

Steps

1. Turn on your computer.
2. As the computer boots, press the F12 key.
3. On the boot menu screen, select Diagnostics. The diagnostic quick test begins.
   NOTE: For more information about running the SupportAssist Pre-Boot System Performance Check on a specific device, see the Dell Support Site.
4. If there are any issues, error codes are displayed.
   Note the error code and validation number and contact Dell.

System-diagnostic lights

The power-status light indicates the power status of the computer. These are the power states:

• Solid white—Computer is in S0 state. This is the normal power state of the computer.
• Blinking white—Computer is in a low-power state, S3. This does not indicate a fault.
• Solid amber—The Computer is experiencing a boot failure, including the power-supply unit.
• Blinking amber—Computer is experiencing a boot failure,, but the power-supply unit is functioning correctly.
• Off—Computer is in hibernation mode or turned off.

The power-status light may also blink amber or white according to predefined "beep codes" indicating various failures.
For example, the power and battery-status light blinks amber two times,, followed by a pause, and then blinks white three times,,  es followed by a pause. This 2,3 pattern continues until the computer is turned off, indicating no memory or RAM is detected.
The following table shows different power and battery-status light patterns and associated problems.
