It may be new to you, but new laptops have Windows 7 on them, not Vista.
New laptops never have a password that was placed on it before you received the computer.
If it's got one now, you or someone who has accesss to the laptop made one, or it isn't your computer and you're trying to access someone else's laptop.
If this is a password for a Windows user ?
If it's a password that was set in the computer's bios.....
- a system access password - you must type it to use the computer at all
- or a hard drive access password - you can get into the bios while booting but you must type it to use the hard drive
- or a bios access password - you must type it to enter the bios Setup
Modern laptops are very wel protected regarding passwords set in the bios. There is no easy way to remove it.
If you are the LEGITIMATE original owner, try contacting the maker of your laptop.
