Always assuming that you do indeed own this laptop, and further assuming that you have the advanced skills necessary to get to the cmos battery (if you don't know what it is, stop here) you need to remove it for about a minute or so, replace and put the laptop back together. Not to be mean, but generally speaking, if you have to ask how to "reset" the bios password you probably don't have the necessary skills to accomplish this. At any rate, this is the solution. Cheers!
