Windows equivalent of /proc/acpi/ibm/light

Question

I want to the led on my Lenovo Thinkpad- T500 to blink programmatically. I see it can be done in linux by

echo "on" > /proc/acpi/ibm/light

Is there any equally simple windows alternative for this. I will be really grateful for any suggestions.

Thanks.

Answer 1

Arkadiusz Wahlig's command line ThinkLight.exe (C source code) will do it under Windows XP/Vista/7 as long as the Lenovo drivers are installed, no Python required.

Usage: ThinkLight.exe <command> [args]
Commands:
  on - turns the ThinkLight ON
  off - turns the ThinkLight OFF
  toggle - toggles the current ThinkLight state
  blink <count> [speed]
    - blinks the ThinkLight <count> number of times,
    - blinks the ThinkLight [speed] times per second, defaults to 3

Answer 2

No. You will need to write a program to do ACPI calls as windows does not expose any of this to the user.

This question would hence be better suited to StackOverflow.

Answer 3

Yes, I realize that I should have asked it in Stack Overflow in the first place. I don't think it can be moved now, because my Stack Overflow and Super User accounts are not linked. I'll move it once they are linked. I am user247077 on Stack Overflow. Meanwhile, this should http://www.thinkwiki.org/wiki/Python_script_for_Windows_to_control_ThinkPad_features give an idea to go about solving the problem.
