How to run the ePSA diagnostics suite

 

The Dell Enhanced Pre-Boot System Assessment (ePSA) diagnostics runs a complete suite of hardware checks on your system to assure that all the devices are in a working condition. This is built into the BIOS and works outside of the Operating system.

You can find out more about the ePSA diagnostics from the article linked below:

 
  1. Power on the Latitude tablet

Testing Hardware using ePSA

The ePSA starts running the Quick Test automatically on all detected hardware without waiting for your input. (Except for the LCD test which looks for your response to an on-screen question.) To select a specific part to test, you can press the ESC key to cancel the Quick Test and select the Thorough Test Mode instead.

Where to get the diagnostic LED indicators and what they mean for you

 

On this particular system, the diagnostic indicator is a single LED on the Power Button and it uses both the color and number of pulses of light to communicate fault codes.

This means the LED indicator consists of two groups of numbers for each color.

  • The first number corresponds to the number of Amber blinks from the LED. (from 1 to 9 blinks)
  • The second number corresponds to the number of White blinks from the LED. (from 1 to 9 blinks)
LED Code Fault Description Suggested Steps
2, 1 CPU
2, 2 System board: BIOS ROM Failure
  • Try updating the BIOS with the latest revision.
  • Contact Tech Support if the issue continues
2, 3 No Memory
2, 4 Memory Failure
2, 6 System board: Chipset
2, 7 LCD
  • Run the ePSA diagnostics
  • Contact Tech Support with results
3, 3 BIOS Recovery image not found
3, 4 BIOS Recovery image invalid
