HP Recommended

My HP EliteBook Folio 1030 G3 is experiencing a startup failure. When I turn on the computer, the fan runs at maximum speed, the screen remains completely black (no display), and the Caps Lock and Num Lock lights blink 4 times consecutively.
The computer does not display the HP logo or boot into the system. I have already tried restarting and performing a power reset, but the problem persists.
I would like to know the meaning of this blinking code and the recommended solution.
