Real Time Clock (RTC) reset
The Real Time Clock (RTC) reset function allows you or the service technician to recover the recently launched model Dell computers
from No POST/No Boot/No Power situations. You can initiate the RTC reset on the computer from a power-off state only if it is
connected to AC power. Press and hold the power button for 30 seconds. The computer RTC reset occurs after you release the power
button.
NOTE: The RTC reset is aborted if the power button is held for less than 25 seconds or more than 40 seconds.
The RTC reset restores the BIOS to defaults and resets the computer's date and time. The computer restarts several times during the
reset process. Depending on how the computer is configured, you may see LED indications during the period the power button is held and
after it is released. Once the reset is complete, the computer restarts and the Dell logo appears indicates reset success.
CAUTION: Once RTC reset is complete, the computer may remain in a no-boot status until the time, date, and other
BIOS settings are correctly set to boot in Windows. Failing to boot immediately after a reset does not mean that the
reset has failed. You must restore the previous BIOS settings, such as the SATA Operation mode (ex. RAID On AHCI) for
the computer to reboot normally.
The following items are unaffected by the RTC reset:
TPM (remains on and enabled if it was in that state prior to RTC reset)
Service Tag
Asset Tag
Ownership Tag
Admin Password
System Password
Hard drive Password
Key Databases
System Logs
The following items may or may not reset based on your custom BIOS setting selections:
Boot List
Secure Boot Enable
Allow BIOS Downgrade
Password clear
The Master System Password is used to clear the admin and computer password.
To clear the system or BIOS passwords, contact Dell technical support as described at www.dell.com/contactdell.
