Diagnostics and LED Indicators

The diagnostics and LED indicators are important on any computer. They are useful both in keeping up with the running status of your computer battery and AC adapter, and as a handy troubleshooting tool.

As this computer is a tablet with a removable keyboard dock, the only diagnostic LED is the battery LED. Below are instructions about how to enter the ePSA diagnostics and what the battery LED can do.

Diagnostics

The Dell Enhanced Pre-boot System Assessment (ePSA) diagnostics performs a check of your hardware to ensure that all devices are functioning correctly. The ePSA is embedded with the BIOS.

Features of the ePSA

The embedded diagnostics provide options for particular devices or device groups allowing 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 to provide extra information about the failed devices.
• View status messages that inform you if tests are completed successfully.
• View error messages that inform you of problems encountered during testing.

Launching the ePSA

1. Power on the Latitude laptop.
2. Tap F12 rapidly during the startup as the Dell logo appears.
3. On the boot menu screen, select the Diagnostics option. The ePSA window is displayed, listing all devices detected in the laptop.

However, if the tablet unit is undocked:

1. Power on the tablet.
2. When the Dell logo is displayed, press the Volume Up button located on the right side of the tablet. The Boot Menu screen displays.
3. Use the Volume Up button to navigate the option to Diagnostics and press Volume Down to select. The ePSA utility window is displayed, listing all devices detected in the laptop.

Testing Devices using ePSA

The ePSA starts running the quick test automatically on all the detected devices without waiting for user input.

To select a specific device to test, user can press Esc to stop the testing.
