Restoring a laptop to factory settings typically involves a set of keystrokes, such as holding Ctrl and F8 or Command R, to access the startup menu and reset options. The keystrokes or steps depend on the type of laptop in question.
The master reset is often in the BIOS menu. For many Windows-based laptops, press F8, Control (Ctrl) and F11, or another function key at startup before the logo appears. Holding the Command and R keys at startup serves the same function on many Apple laptops. Once the proper menu is accessed, use the indicated keys to select the correct reset option. Instructions may vary but typically require the user to agree to deleting all files and installed programs as part of the restoration process. Some newer machines allow for data backup before restoring so files are not lost.
