Enhanced Pre-boot System Assessment - ePSA

The ePSA is a diagnostic utility available on the tablet. This utility includes a series of tests for a tablet's hardware. Customers can run these

code and generates a beep code.

• Automatic Default Operation- runs test on all devices, allowing a user to interrupt and select any device.

• Checks the Master Boot Record for readiness to boot into a full OS environment.

• Tablet panel test.

• Video card.

• Primary battery.

• Multiprocessor cache test.

LCD Built-in Self Test - BIST

Dell laptop PCs have a built-in diagnostic tool that helps you determine if the screen abnormality you are experiencing is an inherent

problem with the LCD (screen) of the Dell laptop PC or with the video card (GPU) and PC settings.

When you notice screen abnormalities like ickering, distortion, clarity issues, fuzzy or blurry image, horizontal or vertical lines, color fade

etc., it is always a good practice to isolate the LCD (screen) by running the built-in self test (BIST).

1 Power on the system.

2 Before the Dell Logo is displayed, immediately press the Volume Up button to get the Boot Menu.

3 Scroll down the Diagnostics and then press the Volume Down button to select.

4 The tablet will begin running the ePSA utility.
