I have a Toshiba A105-S4054 Laptop, purchased in the fall of 06. Recently I had to replace the LCD, for about 160. dollars, all has gone well with that.

Last night, it started shutting itself off. I would restert it, could feel the fan running, and it would get to the desktop, I could move the mouse around, and it would die.

So I removed the battery, tried running directly from the AC adapter, no joy. Tested the AC adapter with a neat little device that glows when there is power, there is power, although the battery is not holding a charge.

I also tried an external monitor just incase.

Then I removed the RAM and reseated it, tried another RAM stick, still would not stay on.

I did manage to get the bios and set it to boot from CD, then tried running a Linux Live, Linspire CD, and it would start, but I still got shut down.

I removed the Hard Drive and tried the Linspire again, same problem. It would recognize it, but then shut down.

So I tore it down to the motherboard basically, but I had missed a few things , and when I popped off the plastic, lots of things came unhooked, like the keyboard, and what seems like is the mousepad, and 2 other things, I went ahead and cleaned out the CPU fan, which did have some lint in it, quite a bit, and the little copper radiator looking thing also had lint, I cleaned all of that off.

Put it all back together, which was a chore, because those tiny connections are hard to get in there. And now it won't even power on at all.

If I tear it all back down tomorrow can I link to photobucket and post pictures here so someone might could tell me if I am missing some connection, or have something wrong in there?

Nothing on the motherboard looked burned or scorched or anything. I would like to know where the bios battery is so I could try removing it and trying again before I give up.

Any help will be GREATFULLY Appreciated:)
