Dell Vostro 1500 wont start, any guesses?

[Cola]

Hello,

I've got a Dell Vostro 1500 which I got from my sister after it wouldn't start anymore. I have taken it completely apart, so the only thing that's still together, is the chassis and motherboard.

It just won't start. The Hard drive isn't spinning, the fan does not start, no lights up when you plug in the charger or put the battery in. I can see that the battery is working and is charged via. the small macbook-style LED's which is on it. And I also know that the charger works because it has been tested successfully on another machine.


The following then, have been established:
It is not the small battery inside it that should just peeled out and reinserted.
It does not help to run with one ram rod, or with other RAM
It doesn't start with either the charger or battery, which I know 100% works.

It has a 15.4'' 1440x900 16:10 monitor, with a Nvidia Geforce 8400M, 2GB RAM and an Intel Centrino 2 dual core processor, so I am prepared to spend a minor amount of money to get it up and running again.

What could be wrong with it then? I kinda hoped that someone in here would be clever in electronics and stuff. I've asked on another Danish forum as well for help.

I personally think that it might would be something to do with something that leads the power from battery/charger to the other components, but I dunno.


Thanks for helping
