Real Time Clock reset
The Real Time Clock (RTC) reset function allows you or the service technician to recover the recently launched model Dell Latitude and
Precision systems from select
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 25 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 is 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
The following items may or may not reset based on your custom BIOS setting selections:
•
The Boot List
•
Enable Legacy OROMs
•
Secure Boot Enable
