Lenovo laptops come with a built-in data deletion feature that can be used to erase all the data on the laptop. This is a great way to clean up any mess you may have made while using the laptop. To use the data deletion feature, first open the Lenovo laptop’s lid and press and hold down on the power button for about 10 seconds. Then release the button and open the lid again. Now, use your finger to scroll down on the screen until you find a blue check mark next to “Data Erase.” Once you have clicked on this check mark, your laptop will start deleting all of its data.
