Well at least it doesn't have a BIOS password. If it did then the laptop might as well be dead and totally useless.
The only thing you can do (unless your friend remembers the password) is to reinstall Windows. Doing so will basically format the C: Drive so any important data would be erased. If it has a D: Drive, then the data there will be safe.
Consult the manual to determine how to reinstall the operating system. Hopefully your friend still has the manual. Other search online to find out how to do it for that laptop model.
