Systems like the Latitude 5480, 5490, or Precision 7510 may show 8FC8 but actually use a SHA-256 hash. For these, you need to extract the NVRAM content using a SPI programmer (hardware-level bypass). This is an advanced procedure involving a Raspberry Pi or CH341A programmer.
Start with the simplest attempts (common backdoor passwords), then move to Service Tag-based generators, and finally, if necessary, the hardware CMOS reset. Avoid motherboard replacement at all costs; it is rarely the solution.

The master password is Q2480JFW or z4jcn3c .
Resolving a BIOS lock is significantly more difficult than resetting a Windows password because the password is stored on a non-volatile chip (EEPROM) on the motherboard. Removing the laptop battery or letting the main battery die will not reset a BIOS password on modern Dell machines.
