Fix that allowed the system to restart and verify the BIOS Update:The RTC reset function allows you or the service technician to recover Dell Latitude, Inspiron, Precision, Vostro, Alienware, or XPS systems from No POST/No Boot situations. - Initiate the RTC reset on the system while it is in a power-off state and is connected to AC power. - Press and hold the power button for 30 seconds. - Release the power button. The system RTC reset then occurs.   Extra Notes from Jesse: 1. RTC reset is available on select Dell Latitude, Inspiron, Precision, Vostro, Alienware, or XPS PCs only. 2. If AC power is removed from the system during the process or the power button is held less than 25 seconds or longer than 40 seconds, the RTC reset process is aborted.
