What to do if SBIOS detects flash corruption on Dell Laptop?
- CChristina HillAug 29, 2025
If SBIOS detects flash corruption on your Dell Laptop, press the power button for over 25 seconds to do an RTC reset. If the issue continues, replace the system board. Additionally, disconnect all power sources (AC, battery, coin cell) and drain flea power by pressing and holding down the power button for 3~5 seconds.
