I have Lenovo laptop running Window XP and I've lost my administrator password!
Lenovo Windows XP Password Removal
There is a built-in administrator account with null password under XP, and then we can opt for the special account to remove/recover the one with a lost Lenovo password on XP from Safe Mode.
Power on Lenovo laptop and press F8. Choose "Safe Mode" and press "Enter" key at the Advanced Boot Option windows.
On the login windows, select the Administrator account and keep the Password column blank (or input the changed password if the default Administrator account password has been reset).
Click "Start" - "Control Panel" - "User Accounts" - Pick the account needed to reset password - "Change the password".
Input a new password and confirm it to complete Lenovo XP password reset.
