Acer manufactures many different models of laptops and desktop computers. The program integrated into the Acer computer's motherboard, called the Basic Input/Output System (BIOS), allows you to configure the hardware, such as the hard drive(s) and optical drive(s). In addition, you can set certain system settings such as the computer's boot sequence. Occasionally, changing the BIOS settings can negatively affect the system, making the system unstable or even inoperable. When this occurs, you may need to restore, or reset, the Acer's BIOS settings to the factory default settings.

Step 1

Turn on or reboot your Acer computer and wait until you see the Acer logo on the screen. This may take up to 30 seconds.

Step 2

Press the required key on the keyboard to enter the system BIOS when prompted. This may vary depending on the model. Watch the screen to confirm you press the correct key. Common keys to press include the "Del" key and the "F2" key.

Step 3

Follow the on-screen instructions to reset the BIOS to the factory default settings. For example, you can use the arrow keys on your keyboard to select the "Load Default Setting" option. The exact wording may vary. Follow the instructions for saving the change and rebooting your computer.
