Hello fl0w3rs, I'm Johrelle a fellow Windows/Microsoft user. I'm happy to assist you.
Acer computers often use a program called Acer Quick Access to display the caps lock indicator.
You can temporarily disable it. Press Ctrl + Alt + Delete simultaneously. Click on Task Manager. Locate the QAAdmin task and click to highlight it.
Click the End Task button. This will temporarily disable the indicator until you restart your computer.
You can also disable Acer Quick Access settings. Look for the Acer Quick Access icon in your system tray. Right-click on the icon and see if there's an option to disable the caps lock indicator or notifications.
