@3aaqib, Welcome to the HP Support Community!

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. As I understand that you are facing no power issue with the notebook. Don't worry as I have a few  suggestions which should help you resolve this issue.

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

When you try to turn it on, do you hear the fan running? Or do you get any beeping noises/blinking lights?

Does the laptop shutdown right away if the charger is disconnected from the laptop?

Have you tried to use a different compatible charger and check if it helps?

Did this happen after a power surge or power outage?

In the meantime, let's try these steps here:  

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 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.
