In the old days, the notebook computers used to come with all the usual features you can find in the desktop computers including all the LED indicator lights for hard drive activity, Num Lock, Caps Lock and more. You can still find such laptops that do have all these LED lights, but more and more new models of laptops are now coming without these LED lights. The only light that you can see in modern laptops comes from the computer screen.
If you want to view the current status of the Num Lock, Caps Lock, and Scroll Lock then you can use the free Vovsoft Keyboard Lights. It is a small but useful simple tool that can display the above-mentioned indicator lights near the system tray of Windows desktop. The lights mimic the traditional large LED lights that glow red and green. The green lights mean that a key lock has been engaged and the red light means that it has been released.
From the options of keyboard Lights, you can choose which of the keyboard locks status should be displayed – Num Lock, Caps Lock or Scroll Lock. You can make it notify in the system tray whenever the key lock status is changed. You can also make it play a sound whenever the lock keys are toggled on. So whenever you change the status of any of these three keys, it will play the sound and flash the notification window displaying the status of all the three lock keys.
The small tool could be useful for anyone who has a laptop that did not come with any of the keyboard indicator lock LED lights. It is free, lightweight and can be used in all the versions of Windows including the latest version of Windows 10.
