Solution:
Some of the latest keyboard and notebook models no longer have indicators for the status of the Caps Lock, Num Lock and Scroll Lock keys.
Keyboard Lights is a straightforward application that provides you with a solution to these issues, as it displays a virtual version of the classic keyboard lights in the system tray area whenever one of these keys is pressed. Whenever you press one of the keys mentioned above, a notification is displayed in the system tray area to let you know which of them are currently active.
