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.

Power and battery-status light
The power and battery status light indicates the power and battery status of the computer. These are the power states:
Solid white:
Power adapter is connected and the battery has more than 5% charge.
Amber:
Computer is running on battery and the battery has less than 5% charge.
Off:
●
Power adapter is connected, and the battery is fully charged.
●
Computer is running on battery, and the battery has more than 5% charge.
●
Computer is in sleep state, hibernation, or turned off.
The power and battery-status light may blink amber or white according to pre-defined "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.
