What to do if flash corruption is detected by SBIOS on Dell Desktop?
- JJoanne AlvarezSep 9, 2025
If your Dell Desktop experiences a flash corruption detected by SBIOS, try the following: 1. Press the power button for over 25 seconds to perform an RTC reset. 2. If the issue persists, consider replacing the system board. 3. Disconnect all power sources (AC, battery, coin cell) and drain flea power by pressing and holding down the power button for 3~5 seconds to ensure all power is drained. 4. Run "BIOS recovery from USB", and the instructions are in the website Dell support. 5. If the problem continues, replace the system board.
