Have you been given the laptop local administrator account password? If so, then log on as "administrator" using the password for that account, which you have been given.
Or has your normal account been given admin rights - i.e. been made a member of the Administrators Group on the laptop? In which case you just log in as yourself, and you have admin rights through the group membership.
It can get further complicated if your PC (and / or your normal account) are members of a domain.
In your position, I would just ask the IT department that provided you with the laptop and password.
