Without applications, and in a flash Before buying a laptop, make sure all the keyboard buttons work
When purchasing a laptop, particularly a used one, we test every component to ensure proper operation before paying the price. These elements—the screen, keyboard, speaker, microphone, mouse, inputs and outputs, etc.—are the most crucial. All components are simple to test, with the exception of the keyboard, which is typically tested by typing every letter in the Notepad application. However, some buttons, like the arrows, do not type any letters. As a result, we will discover a website designed especially for keyboard button testing.
Regardless of the operating system, Key-Test provides a free service to rapidly test all keyboard keys' functionality before buying a laptop. The keyboard will be in front of you when you visit the website using the link below. After choosing Windows or Mac from the menu at the top, start typing on the keyboard. Calculator keys are also supported, as seen in the picture.
The button will turn white when you press it and light blue when you let it go... It is not functioning if there is no change in color. At the top, the button's name is visible.
The mouse can also be tested. The button's name appears in the upper left corner when you press the wheel or the right or left button.
