Netbooks are miniaturized versions of laptop computers, designed specifically for portability and rapid Web access. Produced by several computer manufacturers, netbooks often lack the performance of full-sized laptop computers in favor of reduced size. Resetting your netbook to factory settings erases the contents of the hard drive, returning the computer to the state it was in when it left the factory. The operating system remains unaffected and will not require reinstallation. Instructions may vary slightly depending on your model.
Click the "Start" button on the taskbar. Select the red "Power" button and click "Restart." The computer automatically shuts down and begins loading again.
Quickly press "F10" when prompted by a message on the screen. The option appears before the Windows login screen appears. The F10 key will launch the computer's BIOS utility.
Use the arrow keys to navigate the BIOS menu, selecting the "Restore" or "Load Setup Defaults" option. The name of the option varies between manufacturers.
Confirm you want to restore your netbook to factory settings when prompted and wait while the changes take effect. This may take several minutes.
