Thank you for posting on the HP Support Community


To get the answer to this question, LEDs blink 1 time CPU not functional. 

I’d like additional information in order to assist you better:

  • When was the last time it worked fine?
  • Have you made any hardware/software changes?
  • Have you tried any troubleshooting steps?

While you respond to that, let's try these steps: 

Hard Reset -

1) Shutdown the computer.  

2) Unplug all the Adapter and peripherals connected.  

3) Remove the Battery. ( not for Built-in Battery computer ) 

4) Press and hold down the power button for 15 to 20 seconds.  

5) Plug-in the Adapter and put the Battery back into the computer if it's a (removable battery)

6) Try to turn on the computer and check,


Hope this helps! Keep me posted for further assistance.
