When I got my first notebook computer almost a decade ago, it had all kinds of LED status lights – HDD activity, power status, network activity along with status lights for the Num Lock, the Caps Lock and the Scroll Lock. But these days if you buy a notebook computer, it might not come with all these LED status lights perhaps because they are trying to keep the indicator lights to a bare minimum. If you have got such a computer then you can do two things to have those cool indicator lights for specialized keys (the Num Lock, the Caps Lock and the Scroll Lock) – either attach a full size USB keyboard to your laptop or get an application that displays the LED status of these keys.
For the latter option, you can use a freeware called AlomWare Lights. It is a small Windows application that sticks itself in the notification area of Windows desktop and displays the LED status of the Num Lock, Caps Lock, and Scroll Lock keys in the system tray (next to the system clock). This is very useful for the users who have mini keyboards and their keyboards do not have the three LED lights to show these states.
But unlike some of the similar applications that can also display the LED status in the system tray, AlomWare Lights offers some other very useful and productive functions. For example, you can use it to forcibly keep the Num Lock status always turned on, so that you do not type blanks when using the numeric pad on the keyboard unbeknownst to the fact that you forgot to turn on the Num Lock. Similarly, it can keep the Caps Lock always turned off so that you do not accidentally enter uppercase letters in the password fields.
