SupportAssist diagnostics
About this task
The SupportAssist diagnostics (previously known as ePSA diagnostics) performs a complete check of your hardware. The
SupportAssist diagnostics is embedded in the BIOS and is launched by it internally. The SupportAssist diagnostics provides a set
of options for particular devices or device groups. It allows you to:
● Run tests automatically or in an interactive mode.
● Repeat tests
● Display or save test results
● Run thorough tests to introduce additional test options and provide extra information about the failed device(s)
● View status messages that indicate if the tests are completed successfully
● View error messages that indicate if problems were encountered during the test
NOTE:
Some tests are meant for specific devices and require user interaction. Ensure that you are present in front of the
computer when the diagnostic tests are performed.

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—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
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.
NOTE:
