Specs: Windows vista upgrade to windows 7, AMD Turion 64
I replaced my motherboard because the cmos battery was bad, when i resoldered it the solder came off of the board so i had to replace the board. I have a toshiba A215-S4697 with windows Vista that I updated to windows 7. I switched out everything plugged it up got a screen with the processor information then i was asked for a bios password, i never had one when i tried to enter information my keyboard would not work. i turned off the computer and checked all connections removed and replaced the keyboard started it back up and now i get a black screen.

Soldering irons can really mess up computer hardware; especially the cheap irons. If soldering on the ground side, voltage can find its way into every component connected. ZAP and it's done. The component voltage is so low on newer equipment, you will never detect it went through, until you power it up.
Chances are it's all "toast". Bad components cause a cascade effect that echos throughout the system. You may get it fixed by replacing parts, but it will be unreliable. Think of it like a virus with nothing to stop it. Once anything comes in contact, power applied, it's infected.

Here's a question for you. Where did you get the replacement motherboard?

Was it new from Toshiba or second-hand from ebay?

Your bios password problem with the "new" motherboard has nothing to do with your botched soldering efforts on the old board.

I suspect you have a second-hand motherboard that had the bios password enabled by it's original owner Contact whoever sold you the motherboard and if they cannot provide the password demand your money back.
