SupportAssist, ePSA, or PSA preboot computer assessment diagnostic test can help identify a potential battery failure and, if there is a component failure, report an error code. When you have an ePSA code, you can submit the Service Tag, ePSA error and validation code at the SupportAssist Pre-Boot System Performance Check page, to learn how to proceed.

1. Power on the computer and tap F12 key at the Dell logo screen.
2. In the One Time Boot Menu, select Diagnostics, and press the Enter key.
3. In the Preboot diagnostics, respond to the user prompts appropriately.
4. Review the test results for battery (Figure 3). If the battery test fails, you can submit the Service Tag, ePSA error and validation code at the SupportAssist Pre-Boot System Performance Check page.
   NOTE:

   • Dell also offers an online diagnostics test, browse to the Online Battery Diagnostics page.
   • The test will start automatically.
   • You may be prompted to install or update the SupportAssist program, if so, follow the prompts.
