Dell latitude laptop wont turn on

I was installing windows on my laptop (latitude C840). I deleted the existing partition, created a new one and quick formatted. After formatting it turned off and now will not turn back on. None of the lights flash when pressing the power button, with or with out a/c.
If anyone could shed any light on the problem it would be much apreciated

Hi

Sounds like somethings gone a bit iffy, here the manual for the laptop, make sure things like the memory havent worked loose etc etc.

Regards

bad battery or DC converter?

Nope dont think so. The battery was fully charged and the power was plugged in while I was in windows setup. It could possibly be the charging/power circuit. Does any one know a way of firing up the motherboards in these laptops, other than using the power switch. I am just looking for ways of testing the components, so I can figure out which part needs replacing.
Thanks for your input though
