Only times is the question, which the Notebook for a BIOS has and then whether the password from the outset was or whether it was entered later. If it has a password ex factory, I would enter the names of the BIOS and password with Google, thus as example Award password. There are passwords of kind of condition for BIOSe, which one should try out primarily. If that does not help anything, the possibility into PC gives to be a workshop that perhaps the technicians can make a BIOS resets. How goes with laptops, I do not know unfortunately.
