Ensure that the computer is off and not in a power management mode. If you cannot shut down the computer using the operating system, press and hold the power button for 4 seconds.

NOTE: Ensure that the computer is off and not in a power management mode. If you cannot shut down the computer using the operating system, press and hold the power button for 6 seconds.

7.Disconnect the keyboard and mouse, then disconnect the computer and monitor from their electrical outlets.

8.Press the power button on the computer to ground the system board.

9.Remove the computer cover.

10.Replace the 2-pin jumper plug onto pins 3 and 4 of the password connector (RTCRST_PSWD) on the system board.

NOTE: The password jumper plug must be reinstalled on the password jumper pins in order to enable the password feature.

11. Connect your computer and devices to electrical outlets, and then turn them on.

NOTE: In System Setup, both system and administrator password options appear as Not Set. The password feature is enabled, but a password is not assigned.

Clearing CMOS Settings

WARNING: Before working inside your computer, read the safety information that shipped with your computer. For additional safety best practices information, see the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance.

NOTE: The computer must be disconnected from the electrical outlet to clear the CMOS setting.

1.Remove the computer cover.

2.Locate the 4-pin password connector (PSWD) on the system board.

3.Remove the 2-pin jumper plug from pins 3 and 4.

4.Locate the 4-pin CMOS jumper (RTCRST) on the system board.

5.Move the 2-pin jumper plug from the password jumper to pins 1 and 2 of the CMOS jumper.

6.Plug in AC power to the system and wait ten seconds for the CMOS to clear.

7.Move the 2-pin jumper plug back to pins 3 and 4 of the password jumper.

8.Replace the computer cover.

9.Connect your computer and devices to electrical outlets, and turn them on.

NOTE: You can use the RTCRST jumper procedure above to attempt recovery from a No POST, No Video situation.
