I wonder if anyone could offer me any help with my laptop.

I was running it in my truck via an inverter ( I have to use cord as wont run on battery)I started the engine with the laptop running, and it immediately turned itself off. Now, when I press the on button, it lights up and the fan starts off for approx 3 seconds then just stops and the on button just flashes. Nothing on the screen and does nothing else if you leave it for a while.

I fear I may have blown something inside it, but any ideas would be greatly appreciated

Now for the reason that this happens when you start the motor the Alternator produces a very large spike which the Inverter will Multiply.
