Recovering the operating system
When your computer is unable to boot to the operating system even after repeated attempts, it automatically starts Dell
SupportAssist OS Recovery.
Dell SupportAssist OS Recovery is a standalone tool that is preinstalled in all Dell computers installed with Windows operating
system. It consists of tools to diagnose and troubleshoot issues that may occur before your computer boots to the operating
system. It enables you to diagnose hardware issues, repair your computer, back up your files, or restore your computer to its
factory state.
You can also download it from the Dell Support website to troubleshoot and fix your computer when it fails to boot into their
primary operating system due to software or hardware failures.
For more information about the Dell SupportAssist OS Recovery, see Dell SupportAssist OS Recovery User's Guide at

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
Latitude and Precision 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 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 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
