hello sir, When I turn on my HP EliteBook 840 G5 laptop, the keyboard lights up and within about two seconds, the Caps Lock and Num Lock lights start blinking. They blink on and off three times, then stop. After that, the keyboard light turns off, and the Caps Lock and Num Lock lights blink on and off two more times and then stop again. After a short while, the fan turns on, but the screen stays black and nothing is displayed.
