Hi Welcome to FixYa!
You could try these steps on restoring your laptop into its factory defaults.
1)Turn off your computer if it is on. Wait for the system to shut down completely. Once it is off, press the "Power" button to turn it back on. Press the "F10" button at the top of the keyboard repeatedly as soon as you see the screen turn on. This will let you enter the setup menu.
2)Use the arrow keys to move between the various menu tabs at the top of the screen. Press the "Right" button until the "File" tab is highlighted, then press the "Enter" button to enter this menu. Here you can make changes to the settings of your computer, or in this instance, restore factory default settings.
3)Use the "Up" and "Down" arrow buttons to move to the "Restore Defaults" option, then press enter. You will see a screen asking "Are You Sure You Wish to Restore System Defaults?" Press the "Y" button to continue. The system will begin restoring your default settings. Do not press a button until a screen says "System Defaults Restored."
4)Use the arrow keys to move down to the "Save Changes and Exit" option and press "Enter." The system will save your changes and automatically reboot your computer. You do not need to press "F10" this time as the computer will start Windows normally. You will see the factory settings have been restored once the system loads.
Hope this could help!
