54 Troubleshooting Enhanced Pre-Boot System Assessment (ePSA) diagnostics CAUTION: Use the ePSA diagnostics to test only your computer. Using this program with other computers may cause invalid results or error messages. The ePSA diagnostics (also known as system diagnostics) performs a complete check of your hardware. The ePSA is embedded with the BIOS and is launched by the BIOS internally.

Power-supply unit Built-in Self Test (BIST) XPS 8930 supports a new power-supply unit Built-in Self Test (BIST). BIST can now be performed by connecting the power cord to the power-supply unit. 1. Turn off your computer. 2. Disconnect the power cord from the power-supply unit, and wait for 15 seconds. 3. After 15 seconds, connect the power cord to the power-supply unit. • • If the LED is on for 3 seconds and turns off, it indicates that the power-supply unit is functional.
7. Turn on your computer.
