Laptop not turning on!

[Amirk365]

So here's the deal. My Acer E-15-411 was working ok for 4 years but suddenly, one morning, I pushed the power button and nothing. 10 minutes later it turns on like nothing has happened. Been Googling everywhere and everyone seems stumped by this.
OS: Windows 10 1803
Processor : Intel Celeron N2840
Battery: New and works with another computer without a hitch.
Can anyone here help me?

It's hard to say what the issue is. If the computer is on right now, I would strongly suggest backing up all your files in case the HDD is failing.

Might be the inverter board is failing for some reason. When you turn it on do you hear any fans spinning up or beeps?
