After the Black Macbook a1181 laptop was dropped, it's screen broke and it got some cracks in the top case. It also wouldn't charge the battery. I replaced the screen and the top case. Then I purchased a new battery for it. The new battery wouldn't charge either. I reset the SMC using the online tutorial. After I reset the SMC, the laptop charged the battery, and the battery worked for the laptop. Since this worked, I decided to put the old battery in again to see if it would charge. The old battery wouldn't charge, and when I put the new battery back in it wouldn't turn on without the power. I tried resetting the SMC again multiple times, but it didn't work. Whenever the magsafe power connector breaks, then it turns off. When I put the computer to sleep, and then unplug it, it will go to sleep, and then hibernate or whatever, but it doesn't completely have to be rebooted like if it just gets unplugged. It's been a few weeks since the new battery was charged, but the lights on it indicate that it's still fully charged.

In a nutshell: It's toast.
You dropped it hard enough to break the battery, the screen and the case. My guess: You broke something on the logic board too - maybe something to do with the power converter.
If the HD is still good, I'd look around for a replacement system that matches yours, and swap the HD.

As a last ditch attempt at getting it up on the new battery you could try resetting the SMC then doing a Reset of the PRAM. If that did not do the trick and U wanted more mental anguish, i would run the Extended Hardware test from install disk then do a PRAM reset and hope. After all that a stiff drink and a lie down.

extended hardware test

I do not have the original install disks that came with the computer, I only have the Leopard install disk. Can I run the diagnostics with the install disk? I tried running the install disk while holding down the d key and it didn't work.

Thanks
