When I went to use it the following day, it refused to switch on, and the LED status lights on the front of the chassis didn't light up at all. I did the usual thing like check the power supply (it was fine). I took it to our local and very excellent computer repair shop and they checked everything but couldn't get it to work. They said they see this quite a lot with gaming laptops, often overheating and the motherboard then breaks down.
Wondered if you had a similar experience. Really disapointing as these laptops are really expensive - the 17" one I had was ~ £1200 - never again - I think I'll go for a Raspberry pi instead, LOL :

If no change then with no battery fitted or power supply plugged in to -
if your laptop works with power supply and battery not fitted remove battery and try this.
remove RAM , clean its connector with paper, clean its connection on board with air duster.
Add in battery and power supply and try to power on, if not -
remove both power sources , remove hard drive/s clean connections with air dusters, re add power try again, if not -
remove both power sources , open laptop remove keyboard connecter, clean both sides with air duster, re connect power both and retry it.
If not and all internal dust is removed and it is retried then next -
board not working , it can be likely a capacitor, (9 out of 10 times) get it tested using an esr meter, or use signal generator on square wave and oscilloscope, replace faulty capacitor/capacitors, or other components not replace motherboard.
But if you notice the cpu gpu is melted ... it probably didn't shut down when it was designed to.
