There may be some setting in BIOS that control contrast and brightness. Also , do either brighness or contrast controls seem to be loose. I've seen knobs crack and slip on the shaft. Should be some resistance to turning. (I don't know details of your XPE)
Some laptops have software drivers that control brightness. Suspect that you could load ANSI.sys and a prompt statement in autoexec.bat and get bolded stuff to the screen. All of this, however, is just speculation. Ed Fair
