hi

check this

HP Notebook PCs - Computer Does Not Start and Emits an LED or Beep Code | HP® Customer Support

The red light blinks three times, and then five, short white light blinks (3 long red, 5 short white)

This condition indicates that the computer does not detect the processor (CPU).

Contact HP Customer Support for repair due to system board or CPU failure.

It’s not a red light it’s the white light and it’s blinking on the caps lock key 5 times slowly then 3 times rapidly. I’ve tried the steps you showed me but nothing worked unfortunately, any other suggestions?

HP Recommended

re-read the document if you find anything else...
you say 3 long and 5 short exactly?
what I'm saying comes closest
initially I had indicated the opposite, but it was not correct long / short

The red light blinks five times, and then three, short white light blinks (5 long red, 3 short white)

This condition indicates that the embedded controller cannot reach the BIOS within the established time limit.

  1. Remove all accessory devices from the notebook.

  2. Contact HP Customer Support if the issue persists.

now this is the document we have here
I don't know why hp removed the other documents, which were different
impossible for me to know here, which is correct, the long/short frequency or the color

It’s exactly 5 short (white) lights and 3 rapid(white lights).
Now I turned on my laptop today and theres no caps lock light blinking. It’s just the solid power button that’s on and still and all black screen. What could this mean? 

HP Recommended

No you were correct at first. It is 5 long blinks and 3 short/rapid blinks. But there is no red lights. The blinks are all a white light for both the 5 long and 3 short.  I visited the link you sent me and tried what you told me to do but its still not working:( do you think this could be a motherboard issue? I only had this laptop for less then 2 months it’s brand new:( 

HP Recommended

if brand new, then don't bother, return to seller, use warranty
