A1ctl controls Acer Aspire One CPU, fan, and screen resolution
So what can it do?
Once installed, you’ll notice a small icon in your Windows system tray. Click on it and up pops a menu with options to adjust things like the fan speed, CPU usage, and the screen resolution.
In the screen resolution options, you can toggle between 1024 x 600, 800 x 600, and 1024 x 768. Since that last one is actually more pixels than the Aspire One screen can technically display, you can either use some downscaling action to squash 4:3 resolution to fit on the netbook’s 16:10 screen or scroll up and down a bit to see the top or bottom of your screen.
You can also use A1ctl to enable or disable the webcam, ethernet, or WiFi hardware.
