No Boot After Using Fn & Power Diagnostic Mode

 

When attempting to run e-Diags by pressing the Fn and Power buttons together, the system completes the quick test and exits, but instead of booting to the OS, it returns to the e-Diags screen.

There is no issue when running e-Diags by pressing F12 for a one-time bootup.

Cause

 

When the system boots from the Fn and Power button, the e-Diags flag is set, not cleared. It causes a repeat boot into Diagnostics.
