Here’s the LED codes from HP: https://h30434.www3.hp.com/t5/Notebooks-Archive-Read-Only/HP-Laptop-Error-Blink-Codes/td-p/6142972 So as you will see you have to count the blinks. # First column for the number of blinks. # Second column for location. # Third for component being checked # Fourth for error condition. What is your resul?
