Remove Power-On Password (700, 700C) 

To disable the ThinkPad 700, 700C power-on password, do the following: 
   1. Power-off the computer. 
   2. Remove the battery pack and the bottom cover. 
   3. Locate the password-override connector on the system board.  (See 'System Board') 
   4. Install a jumper between the two pins at position 1. 
   5. Power-on the computer and wait until the POST ends. 
Remove the jumper from the password-override connector when service is completed. 

Remove Power-On Password (720, 720C) 

To disable the ThinkPad 720, 720C power-on password, do the following: 
   1. Power-off the computer. 
   2. Remove the battery pack and the bottom cover. 
   3. Locate the password-override switch on the system board. (See 'System Board') 
   4. Slide the password-override switch to the left position. 
   5. Power-on the computer and wait until the POST ends. 
Slide the password-override switch to the other position when service is complete. 

Reactivate Power-On Password
   To reactivate the password, start the system programs, select Set features from the Main Menu, then select Set password and unattended start mode, and follow the instructions on the screen. 

Remove Privileged-Access Password (PAP) 
    If the PAP is set, then forgotten, it cannot be overridden or removed. The system board must be replaced.  

Musings on PAP Recovery
   Someone claims to be able to clear the PAP for ThinkPads (for a few hundred IIRC). Your best bet is never to enable it to begin with. With the 95s, the home of the PAP has been tracked to the Dallas RTC which has a small protected data storage area. I assume the TP has a similar chip.
