What to do if Flash corruption detected by SBIOS in Dell OptiPlex 7000 Micro Desktop?
- LLaura StoutAug 21, 2025
If your Dell Desktop is experiencing a Flash corruption detected by SBIOS, first press the power button for over 25 seconds to perform an RTC reset. If the issue continues, you can try disconnecting all power sources (AC, battery, coin cell) and drain flea power by pressing and holding down the power button for 3 to 5 seconds. As a next step, run “BIOS recovery from USB”, and the instructions are in the website Dell support. If the problem persists after these steps, consider replacing the system board.
