Real Time Clock—RTC reset
The Real Time Clock (RTC) reset function allows you or the service technician to recover the recently launched model systems
from No POST/No Boot/No Power situations. You can initiate the RTC reset on the system from a power-off state only if it
is connected to AC power. Press and hold the power button for 30 seconds. The system RTC reset occurs after you release the
power button.
NOTE: If AC power is disconnected from the system during the process or the power button is held longer than 40
seconds, the RTC reset process gets aborted.
The RTC reset will reset the BIOS to defaults, un-provision Intel vPro and reset the system date and time. The following items
are unaffected by the RTC reset:
● Service Tag
● Asset Tag
● Ownership Tag
● Admin Password
● System Password
● HDD Password
● Key Databases
● System Logs
● TPM on and TPM Enabled settings are unaffected by RTC Reset and should not cause BitLocker issues
NOTE:
The IT administrator's vPro account and password on the system will be un-provisioned. The system needs to go
through the setup and configuration process again to reconnect it to the vPro server.
The below items may or may not reset based on your custom BIOS setting selections:
● Boot List
● Enable Legacy Option ROMs
● Secure Boot Enable — Allow BIOS Downgrade
