  If your Dell Laptop detects flash corruption, press and hold the power button for over 25 seconds to perform an RTC reset. If that doesn't work, remove all power sources (AC adapter, battery, and coin cell), then drain any remaining power by holding the power button for 3-5 seconds. If the issue persists, the system board may need to be replaced.
