@Ismaelbaig, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
I'm sorry to hear that your laptop is not starting after it overheated. I’ll guide you through a few steps to help diagnose and potentially resolve the issue.

 

Check the LED Blink Pattern

The blinking Caps Lock light is a diagnostic indicator. Count the number of blinks between pauses this can help identify the specific hardware issue. 
Refer to this HP support article for blink code meanings: HP Notebook PCs - Computer beeps or a light blinks during startup | HP® Support

Perform a Hard Reset

This can help clear any residual electrical charge that might be preventing startup:

• Turn off the laptop.
• Disconnect the power adapter.
• If the battery is removable, take it out.
• Press and hold the power button for 15 seconds.
• Reconnect the battery and power adapter, then try turning it on.

Check for Overheating Damage

If the laptop overheated while not in use, it could indicate a hardware fault (e.g., motherboard or thermal sensor failure). Ensure the vents are clear of dust and the fan is functioning.

Try an External Display

To rule out a display issue:

• Connect your laptop to an external monitor or TV using HDMI or VGA.
• Power on the laptop and check if anything displays externally.

BIOS Recovery

If the system is not booting but the power light is on, try a BIOS recovery:

• Turn off the laptop.
• Press and hold Windows + B, then press and hold the Power button for 2-3 seconds.
• Release the Power button but continue holding Windows + B until you hear beeps or see the screen light up. 

I hope this helps. 

Take care and have a good day.
