• Turbo Boost (Intel): Default: Enabled.
  Disabling this locks your CPU to base frequency. Pros: Lower temperatures (65C vs 85C). Cons: 30% performance loss.
• C-States (C1E, C6, C7): Default: Auto.
  Deeper C-States (C7) save more battery but can cause audio stuttering. For Windows 10/11, leave on Auto.
• Intel SpeedStep (EIST): Never disable. Without it, your CPU runs at max clock 24/7, killing battery life.
• Configurable TDP (cTDP): Rare. Found on U-series chips (e.g., i5-8250U). Allows you to increase TDP from 15W to 25W (gains 20% performance) or lower to 10W (fanless operation).
