hp model 15-bs134wm 

ok so in the beginning the screen on my laptop was only playing the top half. the bottom half was black and they were seperated by a perfect line straight across the middle. a couple weeks later the entire screen goes black on me. i then used the hdmi port to watch my tv from it. It worked perfect, so i looked up a fix for it and tryd to start it in safe mode. as soon as i tried safe mode, teh hdmi stopped working and my screen remained black so im basically blind from here on. ive tryd a hard restart. ive tried entering bios still nothing worked. now today i just noticed my caps on light is blinking 4 times repetively.

Hi @Jocko43,

Welcome to the HP support community.
 

We understand you're experiencing a blank screen issue with your HP 15-bs134wm laptop, where initially only the top half of the screen displayed content, later progressing to full black, and now you’re observing 4 Caps Lock blinks repeating in a cycle, with no HDMI output after attempting Safe Mode.

The 4-blink Caps Lock error on HP notebooks indicates a graphics system failure. In your case, this confirms that the issue is related to the integrated GPU or video controller on the system board.
