I see that you're having an issue with notebook not booting up. Now, if you could please tell me how many times the LED light is blinking on the caps lock/num lock key?
Once you find out check this list of causes and let me know which one it is.
I look forward to your response.

OK, if it's blinking just once, then it's indicating the CPU is bad. Now, it could very well be the MOBO but at this point knowing you already replaced the CPU it could be either or. Now that doesn't rule out that the CPU you have now was bad when you used it to replace the old one.
I would suggest calling HP@8004746836 to see what options they have to replace or repair the notebook.
