Probably your grand daughter just replaced the password with another, or added a BIOS password for the PC. Neither can be removed without knowing the password on today's hardware, as they are very secure. So ask the daughter in law for the password, then you can enter the PC BIOS and remove any passwords set. If she also doesn't know what she did or what the new password is, get a new harddisk. If it is the Laptop's PC BIOS password which she set, then get in touch with DELL, they will be able to offer help once you have provided them with proof of ownership.

rindi is correct.  Hard drive passwords are devils to deal with.  The options are three:

1.  Know the password

2.  Pay the manufacturer to deal with it - if it is possible

Many drive manufacturers state that there is no bypass for an unknown password.   Manufacturers that do have methods of bypassing drive passwords require that the drive be shipped to their internal repair facilities with proof of ownership.

3.  Security erase the drive to unlock it

On some drives, this leaves the drive completely erased and ready to reload the operating system.  On others, this leaves the drive completely erased and still locked.

Laptop BIOS passwords are nearly as difficult, but at least Dell has a procedure for dealing with them.  See the EE laptop BIOS password article for details.
