Dell OptiPlex 5250 User Manual

Invoking BIST with user modes
There are two methods to invoke the LCD BIST .
• OSD Toggle
• ePSA
OSD toggle
The rst method of user initiation is via OSD toggle button. The user should press the OSD toggle button and hold it in while the power
button is applied to turn the AIO on. This is the hardware-initiated method that does not require the CPU and BIOS to be functional. The
panel will stay in BIST mode until the BIOS reboots the system. The test duration is approximately 20 seconds which allows 2 cycles of
color bar patterns.
To invoke the BIST test via OSD Toggle:
1 Press and hold down the OSD toggle button.
2 Press the power button to turn on the computer while holding down on the OSD toggle button.
NOTE
: The OSD toggle is located at the right side of the chassis, just above the Hard Disk indicator light.
ePSA
The second method to troubleshoot is via ePSA entry. The user initiates a Pre-Boot POST via F12 function key and the system enters
ePSA. The ePSA menu will have an LCD BIST selection that asserts the proper signals via BIOS commands. The BIST mode will loop for
