Intermittent Power on

[DrMun]

Intermittent power to notebook.  

With known good battery and adaptor, and no LED indicators at adaptor input, notebook does not power on .  When LED lights white at adaptor input on notebook, pressing the on/off button will cause the white led to extiguish and notebook remains non working.  Intermittently, the adaptor input led will light orange, and the notebook will operate normally.  Any ideas on what the problem may be?

Powering with known good battery only, notebook power up remains ntermittent.

Powering with known good adaptor only, notebook power up remains intermittent.

When notebook does power on, diagnostics indicates adaptor (I have two) and battery (I have two), fully functional and good.

Hi @DrMun,

Thank you for visiting the HP Forums! A great place where you can find solutions for your issues with help from the community! I came across your post and wanted to assist you. I understand you are having issues with the Laptop does not power on anymore. Don't worry we'll work together to find a solution for you.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any changes on the PC before the issue started?

Did this happen after a recent update to Windows or upgrade to Windows 10?

After reviewing your post, this looks to be a possible hardware failure. Before you could contact our HP phone support for available service options. I would recommend you try these steps here: 

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 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. 

If you have followed these steps here and still having the issue. I would recommend you contact our HP phone support for available service related options. If your product is out of warranty, please choose paid options to get the tech support number.

Thank-you Jeet_singh!  

I followed all of the troubleshooting directions provided and find the laptop fits into trouble shooting step 5 - "(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. )

I will look into contacting HP for technical support.  A bit frustrating that this HP machine is just out of warranty, and in addition, it has already been to HP warranty repair for a failed keyboard.  Hope not all HP devices are this problematic in quality control.....
