Lenovo ThinkPad computers come with a built-in screenshot tool that allows you to take a picture or video of what you are seeing on the screen and store it in the computer’s memory. To use this feature, first open the Lenovo ThinkPad computer’s lid and press the Fn key to access the system’s main menu. From here, select Screenshot and then press the left arrow key to select the type of screenshot you want to take. You can choose to take a picture or video of your screen using either a digital camera or a microphone.
