A light control center for Razer Blade laptops, in a full Windows window. It changes the performance mode, the fans, the keyboard lighting, the screen and the battery settings straight through the laptop's controller, without Razer Synapse or its background services.
Blade Control grew out of Razer Helper, a tray popup. It keeps Razer Helper's tested hardware code and moves it into a resizable window laid out like a modern control center: page tabs along the top, cards for the settings, and a panel with the laptop's picture, battery, power plan and temperatures.
- Performance: Silent, Balanced and Custom, with Custom's CPU (Low to Boost) and GPU (Low to High) levels. Each power source keeps its own mode, and plugging in or unplugging switches between them. Max fan speed, plugged in, on the models that have it, and the battery charge limit (60 to 99%) on controllers that accept one. On the 2025 and later Blades, on battery, Silent and Balanced use the firmware's Battery Saver and Battery Balanced, as Synapse does.
- Silent really is quiet: Silent also turns Windows' CPU boost off, which is what quiets a Blade 15 Base (2020); Balanced and Custom give it back. An experimental switch in Settings turns this off.
- Battery mode: one switch, and on battery the laptop goes to Silent, the screen to 25% and 60 Hz, the keyboard to 20%, Windows' Energy saver on, and transparency and window shadows off, with an offer to close the apps keeping the NVIDIA GPU awake. Plugging in puts everything back.
- Apps: a profile for each game or app (mode, fans, refresh rate, screen colors, keyboard lighting and game mode, which blocks the Windows key and optionally Alt+Tab and Alt+F4) that goes on while it runs and is undone when it closes, with a notice. Games installed with Steam, Epic Games, Xbox and Battle.net are found for you.
- Lighting: keyboard and logo effects, color and brightness, and the keyboard going dark with the screen, when idle or on low battery.
- Display: the internal screen's refresh rate (Auto follows the charger), a color profile (Standard, Night light, Neutral, Contrast) that stays on after the app closes, whether an external display is connected (and an option to keep running with the lid closed while one is, plugged in), and Integrated graphics only (see below), with whether the dedicated GPU is awake or asleep right now and which apps are using it.
- Battery: the charge, power and time left, the last 24 hours from Windows' own battery report, and the battery's health.
- Optimize: freeing memory, temporary files and the shader cache, the apps keeping the dedicated GPU awake, hibernation, and Razer's own software.
- Device panel: the laptop's picture and model, battery (its watts on the tray icon's hover), Windows' power plan (with a "Razer Blade" plan to install: performance plugged in, battery life on battery), the controller's firmware and the BIOS versions, and the charger in (USB-C and its watts, or the laptop's own; hidden on battery). CPU and GPU temperatures with the last hour's average can be turned on in Settings, Experimental.
- Tray: closing the window keeps the app in the tray; a click on its icon opens it again, and its menu switches the performance mode or ends the app. It can start with Windows.
- Updates: the app looks on GitHub for a newer version once a day, and updates itself in one click: it downloads the release, checks its SHA-256 and restarts, keeping your settings. It can be turned off in Settings.
- Shortcuts, from any app or game: Fn+Del shows or hides the window, and Ctrl+Shift+F1 / F2 / F3 switch to Silent, Balanced and Custom, with a small notice at the top right that never takes the focus. The mode shortcuts can be turned off in Settings.
- Your settings in a file: Settings exports the modes, app profiles and options to a file and imports them back, for a Windows reinstall or another Blade. What only applies to this PC stays out.

A switch on the Display page that turns the dedicated (NVIDIA) GPU off, as Device Manager's Disable does, so everything runs on the integrated GPU: more battery and less heat. It asks for administrator permission, and before turning the GPU off it offers to close the apps using it. While it is on:
- the HDMI and USB-C video ports show no picture, since they are wired to the dedicated GPU (the switch will not turn on with an external display connected);
- games and 3D apps run much slower;
- it stays on after restarting, until it is turned off. A driver update may turn the GPU back on.
This is not a MUX switch: on laptops without one, such as the Blade 15 Base (2020), the internal screen is always driven by the integrated GPU.
While Windows has no "Razer Blade" power plan, the device panel offers Install Razer Blade plan. It adds a copy of Windows' Balanced plan with the changes below and makes it the active plan, without administrator permission.
| Setting | Plugged in | On battery |
|---|---|---|
| Energy performance preference (0 performance, 100 efficiency) | 20 | 80 |
| Processor boost | Aggressive, 60% of it used | Efficient aggressive, 40% |
| Frequency changes | Checked every 30 ms; rise straight to the top, drop gradually | Checked every 100 ms; rise gradually |
| Response to clicks and keys (latency hints) | 99% | 40% |
| Cores kept awake | All; more woken at 60% load | At least 30%; more woken at 85% |
| PCI Express and NVMe power saving | Off | On |
| Wi-Fi power saving | Off | Maximum |
| Intel graphics | Maximum performance | Balanced |
Everything else, such as when the screen turns off or the laptop sleeps, is Balanced's. Silent still turns the CPU boost off in whatever plan is active.
Verified on a Razer Blade 15 Base (2020), a Razer Blade 14 (2025) and a Razer Blade 16 (2023). Every Razer Blade from 2021 on is recognized (Blade 14, 15, 16, 17 and 18, including the 2025 and 2026 models). They use the same commands and are expected to work; a command a laptop's firmware does not have is refused cleanly, and the app hides or explains what it cannot do.
Blade Control is a portable app: nothing to install.
- Build the portable folder (see below) or take it from a release.
- Keep the files together in one folder and open
BladeControl.exe.
The settings and the log live in %LOCALAPPDATA%\BladeControl. With Start at
login on, Windows starts the exe from wherever it was last opened, in the tray.
- Windows 10 or 11 on a Razer Blade.
- The portable build carries .NET inside it. Building from source needs the .NET 10 SDK.
dotnet build BladeControl.slnx
dotnet test tests/BladeControl.Core.Tests
dotnet run --project src/BladeControlThe portable folder: BladeControl.exe, which carries .NET inside it, and
beside it the few native DLLs WPF needs, so nothing is unpacked into the
temporary folder.
dotnet publish src/BladeControl -c Release -p:Portable=true -o distBladeControl.exe --screenshot file.png [page] [width] draws the window into a
picture a few seconds after it opens, then closes; page is one of
Performance, Lighting, Display, Battery, Optimize or Settings. The previews
above were made this way.
| Folder | What it holds |
|---|---|
src/BladeControl.Core |
Everything that talks to the laptop and Windows: the EC over HID, sensors, power plans, devices, settings, the log and the translations. No interface. |
src/BladeControl |
The WPF window: themes, views and view models. |
tests/BladeControl.Core.Tests |
The tests for the core, with a scripted EC so nothing touches the laptop. |
