How to Unlock an IBM ThinkPad T60
IBM-branded Thinkpad T60 laptops from Lenovo are mobile computing devices that feature a keyboard lock for data security. When the lock is enabled, pressing the keys on the keyboard does not result in input to the computer. The lock hampers attempts by an unauthorized user from gaining access to your computer and your files. Lock your Thinkpad using the Function key. The Function key used in conjunction with other keys on the keyboard expand the laptop's number of available features.
Locate the "Fn" key in the lower left corner of your Thinkpad keyboard.
Locate the "F2" key in the upper left area of the keyboard.
Press and hold the "Fn" key, then press the "F2" key to toggle the "Lock" feature. Release both keys.
