Bad cpu or bad mobo?

I've been tasked with figuring out what's wrong with a Toshiba Satelite 1405-s151.
A typical celeron 1.3 low end laptop. The thing won't boot, or post. The power light comes on, the heatpipe gets hot and occasionly the fan runs long enogh to cool it down but that's it. I got it to boot into windows once, but when I restarted it, it just sat there like a farm dog waiting to be kicked.I was curious if any one out there owned something similar and had the same problem.

Power light stays on and doesn't flash? It posted at some point if you got onto windows once? That was the only time it posted? It would be worth it to chase down a processor just to make sure. It could probably handle a faster processor. I'll try to look it up for you if I get a chance.

If it doesn't post one of those 2 components or the memory. If it were a desktop I would include the video card. In your case that is the MB. If it posts occasionally you need to figure out what is different when it doesn't post.

Thanks Rip! unfortunately I don't have a sodimm to swap in to check if that's the problem. I could rip one out of my laughably old Gateway, but it's only a 66mhz fsb on that thing and I doubt that would help . I can get it to boot about once in every 50 or so power button pushes

so if I can get it to do that I'll run memtest. When it does boot up, it runs fine....

Now it doesn't boot at all. The leds come on, but that's it. This thing happens to have this socket 478 processor in it. I'm 80% certain that the cpu is dead in this thing. Would it be worth it springing for a cpu- assuming I can find one?
