Power on Password

the battery fell out so the PW changed??? Wow, you expect us to believe that???
ok, come up with some sob story or something, to make us wanna help (even though we still wont), at least we can have something other than a pitiful story to go on before telling you to F**k off

If the problem was caused by dropping the laptop on the floor and the battery falling out, the only logical solution would be to do the exact opposite of this, in the hope that your original password will return.

So the problem was, laptop falls from the desk to the floor, as it bounces, the battery falls out and then both battery and laptop come to rest (disconnected).

The opposite of this would be the battery and laptop are disconnected on the floor, you need to bounce the laptop off the floor (I would suggest throwing it really hard or kicking it), and as it bounces, throw the battery at it. If you time it just right you should be able to throw the battery into the laptop, if you can then get the laptop (plus battery) to land back on the desk, then that is a bonus. You password would almost definitely return.
