In the event of a hardware issue, which step should be taken after running ePSA diagnostics on the LCD panel?

After running the ePSA diagnostics on the LCD panel, verifying USB input device functionality is a logical next step because it helps confirm whether the issue lies with the display or another part of the system. The ePSA (enhanced Pre-boot System Assessment) diagnostics help identify hardware issues, so if the diagnostics indicate that the LCD panel is functioning correctly, the next step would be to check the input devices to ensure they are working properly. This approach eliminates potential faults that could be related to user interaction with the system, such as non-responsive behavior due to a malfunctioning keyboard or mouse.

Furthermore, examining the USB input device functionality could also provide insights into whether the problem is related to software or peripheral devices rather than the hardware itself, including the LCD panel. This step is crucial in a systematic troubleshooting process, as it helps isolate the cause of the issue more effectively before jumping to more extensive solutions, such as replacing hardware components or resetting settings, which could be unnecessarily time-consuming and costly if the problem does not actually lie with the LCD panel itself.
