Power LED flashes once but the laptop is not turning on.

[sagarkhetwani]

Initially the laptop was turning on but there was no display. The caps lock light was blinking continuously with no fixed numbers. (I counted till more than 10-12 times). I tried to reset the BIOS by pressing the power key for 15 seconds after removing the battery. (Which I learnt from hp troubleshooting). Now the Power LED flashes, the fan starts and then within 2 seconds it turns off. I got it checked from a local service centre, the guy said there is problem with the graphic card. He repaired it and the laptop also started working but when I got it back home it is back to the situation it was. Any suggestions what could possibly be the reason for it?

@sagarkhetwani,

Thank you for reaching out to us on HP Support Forums! I see that you are having issues with the notebook not powering on. Don't worry we'll work together to help you find a solution.

As you have mentioned in your post that you have taken the notebook to a local store where they have diagnosed the problem to be with the graphics card, however after having it repaired you are still having issues with the computer not turning on. I would suggest you could take it back to the local store to have it checked. 

In the meantime, you can perform the below steps: 

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. 

6. Alternatively, you can go through the troubleshooting steps from - HP PCs - No Power or No Boot Troubleshooting

If the issue persists, I would suggest this could be a possible hardware failure with the notebook.

I will share you a private message with details. Please watch your inbox for more information.

Let me know if this helps!

Have a great day ahead! 🙂
