RESETTING THE PASSWORD JUMPER
To disable the power on or setup password features, or to clear the power on or setup password, complete the following steps:
1. Turn off the computer and any external devices, and disconnect the power cord from the power outlet.
2. Disconnect the keyboard, monitor and any other external devices connected to the computer.



WARNING CAUTION CAUTION
To reduce the risk of personal injury from electrical shock and/or hot surfaces, be sure to disconnect the power cord from the wall outlet, and allow the internal system component to cool before touching. When the computer is plugged in, the power supply always has voltage applied to the system board even when the unit is turned off. Failure to disconnect the power cord can result in the damage to the system. Static electricity can damage the electronic component of the computer or optional equipment. Before beginning these procedure, ensure that you are discharged of static electricity by briefly touching a grounded metal object. Refer to the Safety and Regulatory Information guide for more information.

3. Remove the computer covered or access panel.
4. Locate the header and jumper labeled E49.
