Describe the process of initiating pre-boot system diagnostics on a PC.

Lesson 3 Simulation

• Pre-boot system diagnostics can only be run from a USB drive.

• Pre-boot system diagnostics are initiated by accessing the BIOS setup during the boot process.

• Pre-boot system diagnostics are automatically triggered by the operating system.

• Pre-boot system diagnostics are started by launching an application from the operating system.

Describe the role of L-BIST in diagnosing issues related to the LCD power rail.

Lesson 4

• L-BIST analyzes the hard drive for data corruption.

• L-BIST is used to perform self-tests on the LCD to identify power rail issues.

• L-BIST monitors network connectivity during startup.
