labtop
you know the word has been spelt correctly by several members.. or is it a LAB-Top.. is it the ceiling or the roof you want to check out..

Well if it is an UNUSED LaPtop .. that would assume the owner would not be that literate and the password would be dirt simple.. try a middlename of a family member, initials, password, or even laPtop... Try social engineering a password.. try "Hey stepdad..you cool dude.. thats a cool laPtop you have there.. can you open it up so I can have a peek at how bad it realy is.. perhaps if you open up a little o'le user account as well ..Please" .. the last word being the most efficient SE word I have ever used....
If you break into the pc by other methods I hope your step dad is a more forgiving person than I would be.. cause when you are finaly able to sit down.. your bum will be 12 inches closer to your head.. but then.. Why would your Sister and Stepdads LaPtop be on your computer desk in the first place..? but then not every home has a pc in the kids bedroom.. some have them in the entertainment area of the house (shut up mark)..

hmmm dunno why i bothered.. fertilizer is cheap.. and this thread is full of it..
