Thank you for posting on HP Forums, MKazi is at your service. 

I understand that you have an HP Envy series laptop. I read that there is a ticking noise from the laptop and the power button light is flashing. Not worry, I'll do my best to help you. 

It could be a noise from the hard drive as it might have failed. But before we conclude the issue I would like to know the following information:

• What is the exact laptop model no? This link will help you to find the model no: http://hp.care/2bygf7l
• Did any hardware changes or software updates happen on the laptop recently?
• What was the last thing happening on the laptop before this issue started?

While you respond to that, I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

• Power off the laptop.
• Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.
• Disconnected AC adapter from the laptop.
• Press and hold the power button for 15 seconds.
• Reconnect the battery and plug the AC adapter.
• Power ON the laptop.

In case the ticking noise stops then please continue to perform a BIOS rollback.The steps mentioned under "Step 1: Recover the BIOS using a key press combination" from this HP document will help.

If the ticking noise continues then you may reach out to our HP phone support team to check the available service options for your HP laptop. 

Hope this information helps. Feel free to keep me posted. 

All the best! 🙂

Hi MKazi, it's HP ENVY TouchSmart 15-j151nr Touchscreen Notebook with i7 4th generation CPU, 16G ram and 1 TB drive, the model was  I purchased it in March 2014. 

I did try the steps you mentioned, but there was totally no response - no ticking noise anymore, just completely no response.

I remembered the charging light was white which means the battery was fully charged.

I switched the battery to the old one which didn't use for a while, the battery charging light became orange.

I charged it for 30 min, press the power button.

This time I saw the dots in circle on screen, but then the fan came on and blowing out hot air and the screen went blank.

Hit F12, the notebook lost power completely, it seems it may have short circuited and the charging light was gone too.

Switch the battery again, the charging light is not on; checked the charge cable and it had power.

Pick up the notebook and heard some sound from loose part inside.

My son told me that the notebook had an update couple days ago.

He was using it in the morning. I picked him up in the afternoon for school break.

The issue occurred when he tried to start the notebook after came home about an hour.

The next morning, I took the notebook to a repair shop, and it was surprised that the computer was able to boot up, but it won't charge anymore. 

The battery was fully charged, I immediately copied all files to a USB drive.

Based on the symptom, we suspected the issue is with the Motherboard power circuit - the laptop would be useless after the battery is drained. 

The laptop is dead now. I press and hold the power button, the charge light is white and flash couple times.
