The Precision T7400 BIOS level password can be reset using the board jumpers – The password enable jumper and a RTC_RST (Real Time Clock Reset) jumper are both located on the systems motherboard next to the SATA ports. Password Enable Jumper
PSWD - Password enable. The system password will be cleared and disabled when the system is started with this jumper removed.
Pins 1-2 shorted enables password
NVRAM Reset JumperRTCRST - Clears NVRAM. The NVRAM will be cleared when the jumper is closed (use the jumper from the password bridge). To properly clear; AC power must be applied (not necessarily turned on) to the system for about 10 seconds while the jumper is closed.
Pins 1-2 shorted clears NVRAM
