Computers that have been setup with a power on password are virtually impossible to guess if you have forgotten the password.
Passwordprotection is setup to prevent people accessing the computer withoutauthorisation. There are no backdoor passwords you can use to get in.

Passwordprotection is usually set up on two levels, first on boot up and secondit may also include a password on the hard drive. This is to preventthe hard drive being taken out of a computer and inserting into another(it won't work in another computer).

If the password is saved inthe BIOS then it is possible to remove the password by removing theBIOS battery for 1/2 + hour, then reinsert the battery and configurethe BIOS again with the date. time, etc. and allow to to boot up intoWindows.
Laptops such as IBM Thinkpads, Compaqs use a EEPROM chip tostore these passwords and removing the BIOS battery won't work. If youare skilled electronically, you can build a piece of hardware and witha program read the contents of the EEPROM to identify the password,then use this password to get into the computer and then if you canremove the power up password and/or hard disk password or change them.
