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.

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. BIOS Setup 95
