Assume these options appear on consumer and business notebooks or embedded systems that use InsydeH2O UEFI firmware; implementations and exact labels vary by vendor.

• Fan Profile / Smart Fan: Choose performance vs quiet. Use balanced or adaptive unless testing thermal limits.
• Thermal Throttling / TDP Limits: Controls CPU power/thermal behavior. Leave default unless tuning for performance or silent operation.

Recommended settings (general guidance)

• Leave Secure Boot enabled unless you must install unsigned OS components or older OSes; disable only temporarily for specific tasks.
• Keep TPM/fTPM enabled if you use disk encryption (BitLocker) or platform attestation.
• Use AHCI for SATA unless you need RAID; switching modes after an OS install typically requires driver changes.
• Enable virtualization (VT-x/AMD-V) if you run virtual machines or developer tools; otherwise you can disable to reduce attack surface.
• Leave C-States enabled for battery devices to save power; if you need low-latency compute, consider limiting deep C-states.
• For battery longevity on portable devices, enable battery conservation/charge threshold features if available.
• Avoid manual changes to DVMT or integrated graphics pre-allocated memory unless troubleshooting specific graphics issues.

• Modify hidden setup variables with UEFITool, IRFExtract, or H2OEZE.
• Flash back using an SPI programmer (risk of bricking).

Changing the wrong voltage or clock speed can render the laptop entirely unbootable. Thermal Throttling or Overheating: Fan Profile / Smart Fan: Choose performance vs quiet
