2. BIOS / Firmware

  • BIOS type: Phoenix/Award/AMI UEFI variants depending on OEM firmware releases for the specific laptop model.
  • Common features:
    • Boot order configuration (HDD, optical, USB, network).
    • SATA mode: AHCI/IDE options (modern boards default to AHCI).
    • CPU features: Intel SpeedStep, virtualization (VT-x) enable/disable.
    • Memory remapping and event logging.
    • Power management: ACPI settings, wake-on-LAN (if supported).
  • Updating: Firmware updates must match the exact laptop model and board revision — using a mismatched BIOS can brick the system. Use manufacturer-provided BIOS utility or a recovery method with a USB BIOS flash stick if supported.
