If the following symptoms are present, they may indicate damage caused by nonwarranted activity: Missing parts may be a symptom of unauthorized service or modification. HDD spindles can become noisy if subjected to excessive force or by being dropped. I9990303 errors can be caused by exposure to strong magnetic fields. How to Disable the Power-On Password: 1. Power-off the computer. 2. Open the keyboard, and remove the diskette drive or CD-ROM drive and the battery pack. 3. Install a jumper on the power-on password connector on the left side of the FDD connector. (See "Power-On Password Connector" on page 345 for location.) 4. Reinstall the battery pack and the diskette drive/CD-ROM drive. 5. Power-on the computer and wait until the POST ends. 6. Verify that the password prompt does not appear. 7. After the service check is completed, remove the jumper. To reactivate the password, set the password again. Supervisor and Hard Disk Passwords: The supervisor password and the hard disk password (HDP) are security features that are used to protect the system and the hard disk data from unauthorized access. No overriding capability is provided. If only a hard disk password is set, obtaining permission from the password owner to unlock the password is a prerequisite for running diagnostic tests and performing service. If both supervisor password and hard disk password are set, you can enter Easy-Setup by pressing the Enter key or power-on password at the supervisor password prompt. In this case, the Password, Start up, and Initialize icons cannot be selected. See "Password Combinations (POP, HDP, PAP)" on page 239 for more information about passwords. Power Shutdown Switch: The power shutdown switch resets the system regardless of the microcode status and forces the power off. Use this push button to power-off when power is not completely off or the microcode is in a hung state. See "Rear View" on page 342 for the power shutdown switch. 204 IBM Mobile Systems HMM
