Thank you for your inquiry. I am happy to help.
I grasp that your notebook will power on but the screen remains black or blank and the Caps Lock light blinks two times intermittently. You tried connecting an external monitor but there was no change. Here is a link HP Notebook PCs - Troubleshooting LED Blink Codes or Beep Codes During Startup or Boot. As two blinks indicate a corrupted BIOS here is a link to HP Notebook PCs - Restoring the BIOS. Please let me know the outcome.

Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post serial numbers and case details.
