PC Server 300 - Power-on password cannot be reset
Applicable to: World-Wide
Symptom
8640 system has a power on password set, but the password has been lost by the customer and needs to be reset to allow system use or service access. There is no reference in the service or user documentation of the Server 300 for setting or removing the power-on password.
Problem Isolation Aids
The system is a Pentium model.
Fix
There is no jumper on the system board which will clear a Power-on Password. To remove a lost power-on password, CMOS memory on the system board must be cleared. The following procedure will clear the power-on password, but will also require the system to be totally reconfigured.
1. Remove the SRAM (Static Random Access Memory - CMOS) module from the socket at U50, located just above the IDE and diskette drive connectors (Refer to page 51 of the "User's Handbook" for the system board connector locations).
2. Wait for 5 minutes (to allow the module drain or discharge).
3. Re-install the SRAM module in its socket, being careful not to bend the pins. Also be certain the MODULE IS PROPERLY ORIENTED, otherwise it could be DAMAGED. See diagram below.
4. Then, run the SETUP again.
