A small tray utility for ThinkPad laptops. Control the status LEDs, CPU fan, and keyboard backlight, and keep an eye on CPU temperature, fan speed, and battery, all in one place.
Turn the power, red dot, microphone-mute, and sleep (moon) LEDs on, off, or into their blink state.
Switch the fan between firmware Auto and Full speed for a quick cooling boost.
Set Off, Low, or High. Optionally remember the level across sleep and restart, and dim it when apps go full screen.
See the CPU temperature (color coded) and current fan RPM at a glance, right in the window.
Charge level and state, plus battery health and cycle count where the hardware reports them.
Uses the signed PawnIO driver so it runs on Windows 11 with Memory Integrity enabled. WinRing0 is the default on other systems.
It talks to Lenovo ThinkPad embedded controllers, so it's meant for ThinkPads, not other brands. Not affiliated with Lenovo.
It speaks directly to the embedded controller, so keep just one instance running — don't launch a second copy at the same time.
Self-contained, no telemetry. It isn't code-signed, so if SmartScreen warns you, click More info, then Run anyway.
