Laptop does not turn on and is dead

[Amaranto]

When pressing the power button the laptop does not turn on, it doesn't show any signs of a life, I pressed for more than 30 seconds but it still does not turn on.

Only for some 10-15 minutes it would do the following:

1. I would do a short press like how I would do normally to turn it on

2. The power button blinked, and when I plugged power chord the led that sogbals charging as well (which was white because the battery was full anyway). They would blink in sync and their were all long 3 second blinks with 1 second pause between one blink and the next.

3. Only when I pressed again for longer than 15 seconds, the power button turns off again

4. I would not hear any sign of activity coming from the computer, no sound, no clicking, yet when I left the blinking on for a couple of minutes to see if that would change anything the upper left quadrat of the notebook, near the power button, was warm.

After some minutes though it stopped, and now it doesn't show any sign of life whatsoever. 

All I know is that the battery was fully charged from the day before, it's an internal built-in batter so I can't remove it as I still have 4 months of warranty left.

I will contact the support tomorrow morning to see if I can send to repair under warranty, but I wanted to know if there was anything whatsoever that I had forgotten to do to solve the problem, regardless.

@Amaranto Have you attempted to connect the device to an alternate power cord or adapter?

Or check with another wall outlet, excluding any surge protectors to check if it works?

While you respond to that, here's  the best way to resolve the issue, using the HP Guided Troubleshooter:

If the above doesn't help or the steps are insufficient, check the below steps:

Let's start with a hard reset of your notebook computer before you try any other troubleshooting steps.

Reasons for a hard reset

A hard reset has the following effects:

• Clears the memory.

• Reestablishes the connection between the BIOS and the hardware

The following conditions can be helped by the hard reset:

• Windows stop responding.

• The display suddenly goes blank.

• The computer does not wake from sleep or hibernate modes.

• Software applications freeze or fail to respond.

Hi, sorry for the delayed response. 

All your suggestions were useful, unfortunately turns out my motherboard was dead and the hp center had to substitute it for a new one, I'm lucky the laptop was still under warranty.

Have a nice day!
