G-Helper is a free, open-source Windows control application from Serge’s community project for ASUS laptops and handhelds. It selects performance modes and adjusts graphics, cooling, charging, lighting, and compatible peripherals. Available controls depend on the device’s hardware and firmware.
What a performance mode changes
Silent, Balanced, and Turbo select ASUS firmware presets with their own power limits and fan behavior. G-Helper pairs each with a Windows power mode, from power efficiency through best performance. Users can change that pairing under Fans + Power.
Custom modes combine a firmware preset with overrides that users save. The application can remember different performance choices for battery and external power, then switch when the power source changes.
Fans follow temperature points
The fan editor connects temperature points to fan-speed percentages. Apply sends the curve to firmware, which continues controlling the fans in real time. Some models reject custom curves or interpret the same points differently.
CPU power and tuning
Per-mode CPU settings also include sustained and boost power limits and a Windows boost policy. Firmware can clamp or ignore limits it does not accept. On compatible AMD systems, optional undervolting and temperature controls communicate with the processor’s management controller. Those controls require administrator access.
Integrated and discrete graphics
GPU modes determine which graphics processors operate and which one drives the laptop screen:
| Mode | Graphics behavior |
|---|---|
| Eco | Disable the discrete GPU; use integrated graphics |
| Standard | Enable both; integrated graphics drives the screen |
| Ultimate | Enable both; discrete graphics drives the screen |
| Optimized | Use Eco on battery and Standard on external power |
Devices without GPU-disable or display-switching support omit the corresponding controls. NVIDIA tuning adds core and memory offsets, a maximum clock, GPU power, Dynamic Boost, and temperature targets. G-Helper also toggles a compatible XG Mobile external GPU dock; deactivation can close GPU applications and asks for confirmation.
Screen and charging choices
Display controls select refresh rate and overdrive. Auto chooses a lower refresh rate on battery and the maximum on external power. Compatible panels add Mini-LED zone switching, flicker-free dimming, visual presets, and color-gamut selection. G-Helper invokes ASUS’s display component for visual modes and gamuts.
A charge target stops battery charging at the level the user chooses. Firmware resets that target after a restart, and G-Helper reapplies it when it starts. Charging can continue before the application opens.
Keyboard lighting and lid panels
Users choose keyboard colors, animation modes, and separate backlight timeouts for battery and external power. AniMe Matrix can display image animations, a clock, or an audio visualizer. Its image controls load frames from an animated GIF and show them on the lid panel. Slash Lighting offers patterns, brightness, and audio effects on compatible devices.
Keys can launch actions
G-Helper handles Fn-Lock and shortcuts for performance modes, display brightness, and graphics switching. Extra settings can remap special keys to an application path or a Windows key combination. Pressing that key launches the program or sends those keystrokes.
External ASUS controls
A compatible mouse, keyboard, or headset adds a device-name button that opens its settings. Mouse controls set DPI, polling rate, button bindings, and lighting. Ordinary bindings and DPI settings remain in onboard memory; shortcut Combos require G-Helper to keep running.
The keyboard panel shows a layout where users pick colors or remap individual keys. Those changes stay on the keyboard after the app closes. Headset controls include equalizer presets or custom sliders, microphone noise reduction, sidetone, and idle power settings. Each model exposes its own supported options.
Readings over a game
The main interface shows processor temperatures, fan speeds, and battery status. A hardware overlay adds foreground-game FPS, power draw, load bars, and a power-history chart. Shortcuts toggle it, move it, resize it, or change its detail level.
The overlay follows compatible DirectX or Vulkan games as users switch between them. Older exclusive full-screen games may hide it. When the discrete GPU powers down, its readings disappear while CPU and fan readings continue.
Model-specific updates
The Updates section checks ASUS’s website for the laptop model and highlights new BIOS or driver downloads. Its links open the official ASUS downloads for that device.
