I need a free password to login into my new toshiba laptop a250 or a key combination to reset the computer

"Hacky" needs a password!

If computer is actually new, take it back to place of purchase. New computers run the welcome setup on first run. There is no key combination for Windows' password resets.

Alternatively, you can wipe the hard drive and reinstall Vista from the Vista operating system CD that came with the computer.

Nice try "hacky".

It ain't going to happen here!
