Updating my HP Pavilion - 15z this morning. Now has black screen and won't power up.

[Scook4]

I was doing some Windows updates on my HP Pavilion - 15z this morning. When I went to check on the laptop after about 15 minutes the screen was black, the laptop was unresponsive, and will not power up. The power supply is putting out 19 volts, no load. The charge light on the laptop is not on. Holding down the start button for 15 seconds does not start the laptop.

@Scook4 Welcome to HP Community!

I understand that the laptop will not power on.

Have you tried with different adapter?

Perform the below steps: 

If the computer does not start, the LED lights do not glow, and the display is black, 

you can perform one or more of the following actions to resolve the no power issue: 

(Click on the blue letters to get more details about each step) 

1. Examine the adapter and power cord for physical damage 

2. Test the power from the AC wall outlet to the notebook connector 

3. Start the computer using the battery only 

4. Check that the lid switch moves freely 

5. When you have completed the troubleshooting steps, there should be power available to the computer. When you press the power button, the LEDs should glow, and you should hear the sounds of the fan and the hard drive spinning. 

   • If the battery does not accept the charge or the notebook does not turn on without the AC adapter, contact HP to order a replacement battery. 

   • If the LEDs do not glow, and there are no other indicators of power being available to the computer, contact HP for technical assistance in troubleshooting a potential problem with the AC power connection or the system board. 

   • If the LEDs blink, or the computer beeps, but it does not start, go to HP Notebook PCs - Troubleshooting LED Blink Codes or Beep Codes During Startup or Boot. 

   • If the LEDs glow but the computer does not start on either battery or AC power, go to Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot.
