+
+## User Preferences
+
+```
+Power Profile: Performance
+Use Case: Gaming
+Battery Priority: Balanced
+Performance Mode: Maximum
+Special Requirements: 
+  - Gaming performance priority
+  - Prevent thermal throttling
+  - Fast system wake/sleep
+```
+
+## Generated TLP Configuration
+
+### General Settings
+```bash
+TLP_ENABLE=1
+TLP_WARN_LEVEL=3
+TLP_DEBUG=0
+```
+
+### CPU Management
+```bash
+# Performance-oriented CPU scaling
+CPU_SCALING_GOVERNOR_ON_AC=performance
+CPU_SCALING_GOVERNOR_ON_BAT=ondemand
+
+# Aggressive frequency scaling on AC
+CPU_SCALING_MIN_FREQ_ON_AC=800000
+CPU_SCALING_MAX_FREQ_ON_AC=4700000
+
+# Conservative on battery to preserve power
+CPU_SCALING_MIN_FREQ_ON_BAT=800000
+CPU_SCALING_MAX_FREQ_ON_BAT=3200000
+
+# Platform profiles for gaming performance
+PLATFORM_PROFILE_ON_AC=performance
+PLATFORM_PROFILE_ON_BAT=balanced
+
+# CPU energy performance preference
+CPU_ENERGY_PERF_POLICY_ON_AC=performance
+CPU_ENERGY_PERF_POLICY_ON_BAT=balance_performance
+
+# Turbo boost settings
+CPU_BOOST_ON_AC=1
+CPU_BOOST_ON_BAT=1
+
+# HWP (Hardware P-states) settings
+CPU_HWP_DYN_BOOST_ON_AC=1
+CPU_HWP_DYN_BOOST_ON_BAT=0
+```
+
+**Rationale**: Gaming requires maximum CPU performance on AC power. On battery, we use ondemand governor to balance performance with battery life while still allowing turbo boost for responsiveness.
+
+### GPU Power Management
+```bash
+# NVIDIA GPU settings
+RUNTIME_PM_ON_AC=auto
+RUNTIME_PM_ON_BAT=auto
+
+# Radeon DPM (if applicable)
+RADEON_DPM_STATE_ON_AC=performance
+RADEON_DPM_STATE_ON_BAT=balanced
+
+# Intel GPU settings
+INTEL_GPU_MIN_FREQ_ON_AC=300
+INTEL_GPU_MAX_FREQ_ON_AC=1300
+INTEL_GPU_MIN_FREQ_ON_BAT=300
+INTEL_GPU_MAX_FREQ_ON_BAT=800
+```
+
+**Rationale**: Dedicated GPU performance is prioritized on AC power for gaming. Battery mode reduces GPU frequency to conserve power.
+
+### Disk Management
+```bash
+# Aggressive disk performance on AC
+DISK_APM_LEVEL_ON_AC=254
+DISK_APM_LEVEL_ON_BAT=128
+
+# No spindown timeout for SSD
+DISK_SPINDOWN_TIMEOUT_ON_AC=0
+DISK_SPINDOWN_TIMEOUT_ON_BAT=0
+
+# SATA link power management
+SATA_LINKPWR_ON_AC=max_performance
+SATA_LINKPWR_ON_BAT=med_power_with_dipm
+
+# NVMe power management
+AHCI_RUNTIME_PM_ON_AC=on
+AHCI_RUNTIME_PM_ON_BAT=auto
+```
+
+**Rationale**: Fast game loading requires maximum disk performance on AC. SSD doesn't need spindown timeout. Battery mode uses moderate power saving.
+
+### Network Management
+```bash
+# WiFi power management
+WIFI_PWR_ON_AC=off
+WIFI_PWR_ON_BAT=on
+
+# Ethernet wake-on-LAN
+WOL_DISABLE=Y
+
+# Network device power management
+RUNTIME_PM_DRIVER_DENYLIST="mei_me nouveau nvidia"
+```
+
+**Rationale**: Gaming requires reliable, low-latency network connectivity. WiFi power saving is disabled on AC but enabled on battery to conserve power.
+
+### USB and Peripheral Management
+```bash
+# USB autosuspend for power saving
+USB_AUTOSUSPEND=1
+USB_EXCLUDE_AUDIO=1
+USB_EXCLUDE_BTUSB=1
+USB_EXCLUDE_PHONE=1
+
+# Exclude gaming peripherals from autosuspend
+USB_ALLOWLIST="046d:c52b 1532:0037"  # Gaming mouse and keyboard
+
+# Runtime PM for USB devices
+USB_AUTOSUSPEND_DISABLE_ON_SHUTDOWN=1
+```
+
+**Rationale**: Gaming peripherals need to remain active for immediate response. Audio and Bluetooth devices are excluded from autosuspend to prevent interruptions.
+
+### Thermal Management
+```bash
+# Thermal zone trip points (prevent throttling)
+TEMP_LIMITS_ON_AC="85/95"
+TEMP_LIMITS_ON_BAT="80/90"
+
+# Fan control (if supported)
+FAN_SPEED_ON_AC=auto
+FAN_SPEED_ON_BAT=auto
+```
+
+**Rationale**: Higher thermal limits on AC power allow for sustained gaming performance. Battery limits are lower to prevent overheating during mobile use.
+
+### Audio and Multimedia
+```bash
+# Audio power management
+SOUND_POWER_SAVE_ON_AC=0
+SOUND_POWER_SAVE_ON_BAT=1
+SOUND_POWER_SAVE_CONTROLLER=Y
+```
+
+**Rationale**: Audio power saving disabled on AC for gaming audio quality. Enabled on battery for power conservation.
+
+### System Sleep and Wake
+```bash
+# Fast resume for gaming
+RESTORE_DEVICE_STATE_ON_STARTUP=1
+DEVICES_TO_DISABLE_ON_STARTUP=""
+
+# USB device handling during sleep
+USB_EXCLUDE_WWAN=1
+USB_EXCLUDE_PRINTER=1
+```
+
+**Rationale**: Fast wake/sleep cycle for gaming sessions. Critical devices remain configured for immediate use.
+
