How to Run Forced ePSA?

A hardware failure may prevent your PC from booting. If you’re experiencing a boot failure, you can run a forced ePSA test by pressing the F2 key on the Dell logo screen. The forced ePSA test will execute a number of hardware tests, including inspections of the power supply, battery, and internal components (such as cables to hard drives and video cards).

What to Expect During the ePSA Test?

During the ePSA test, you may notice the internal fans of your computer spinning up. Additionally, the ePSA will ask you if you want to proceed with the 30-minute long memory tests. If you don’t think you have a memory problem, you can decide to skip these tests.

Recording Error Codes

An error message will appear if the ePSA test runs into a hardware issue. When reporting the problem to Dell Technical Support, it is crucial to write down the error code and the validation code that is displayed. You can also look up the error code to get the detail about the error.

Contacting Dell Technical Support

You should contact Dell Technical Support with the error code and validation code if the ePSA test detects any hardware p problem. They will be able to help you to resolve the issue if the system is in the warranty period. You must contact Dell directly if the system is no longer under warranty.

Overall, the Dell ePSA (Enhanced Pre-Boot System Assessment) is a powerful tool that can help you troubleshoot the hardware of your system from outside the operating system (OS). Whether you’re experiencing a boot failure, a hardware failure, or simply want to ensure your system is running optimally, the ePSA test can provide valuable information and guidance. If you have any questions or need further assistance, don’t hesitate to contact Dell Technical Support Personnel.
