not sure about laptops, but the processor should be a large chip with heat-sink on it and a fan. when you turn it on, does nothing happen?

If I were you I'd do a search on Ebay for the model of laptop you are building. If you luck out you may find somebody selling a motherboard that has a pic of it. If you could see a pic of it and imagine how it would mount in the chassis you should be able to see where the chip would go

Could be a bad power supply, a dead motherboard, a bad battery, or even a bad power switch.

The CPU on a laptop is generally close to whatever area of the laptop has the most holes in it for ventilation.

I hate servicing laptops. Just dissected one yesterday. Ugh.

No vent holes at all? is it like 10 years old?

You can't run a laptop these days without some sort of air induction. Even that laptop I worked on yesterday was only a 900 MHz. CPU, and it had to have a heat pipe and a fan. My own Athlon 2000+ laptop has about the same ventilation as that 900 MHz. one, but has a bigger heat sink inside.

Hell, I think even my last laptop, which had a 100 MHz. CPU, had ventilation.

The cpu on my laptop is located under the keyboard assy.

Dells aren't too terribly hard to fix tho the pain is getting the thing open to work on, after that it's cake. You're gonna have to disconnect the lcd screen and pull the keyboard/keyboard bezel off. One that's done look at the back of the laptop for vent holes, there have to be some, once you find them looked for a hunk o metal screwed to the board, it may be on top, tho i doubt it, so you'll have to unscrew the board from the rest off the case. It should be there. If all else fails and you can do it, take some pics of it and post them. It'll help us help you!
