How to Update BIOS

Updating the BIOS is a process that involves flashing the BIOS to install new features and fix hardware problems. The following article provides instructions on how to update the BIOS on a Dell computer, as well as general instructions for other manufacturers.

Before proceeding with the BIOS update, there are important considerations to keep in mind:

  1. Verify the need for a BIOS update: BIOS updates are not typically necessary unless recommended in a troubleshooting guide or if you encounter compatibility or stability issues with new hardware. Check the current BIOS version and compare it to the version stated on the manufacturer’s website to confirm if an update is required.
  2. Ensure a stable power source: To prevent any interruptions during the update process, make sure your computer remains powered on. If you’re using a desktop, simply ensure the power source is reliable. For laptops, connect it to a power outlet and avoid any power disruptions.
  3. Back up your data: Although a BIOS update should not affect your files, it’s always a good practice to back up your data as a precautionary measure before making any changes at the BIOS level.

What to Know

To begin, ensure that a newer version of the BIOS is available and make sure to backup your data. If you’re using a laptop, connect it to a power source.

For Dell PCs: Visit Dell’s support page and click on “Download & Install SupportAssist.” Then, select the “BIOS” category and proceed to download.

If you’re using Windows, select “Update” and wait for the “Update successful” message. Choose “Yes” to restart your computer.

Please note that the steps provided are specific to Dell PCs. Different manufacturers may have slightly different processes, so it’s important to refer to their respective support pages for accurate instructions.

Updating Dell BIOS:

The following steps provide specific instructions for updating the BIOS on a Dell computer. Remember that each BIOS manufacturer may have a different process. If you’re not using a Dell, refer to the next section for general steps.

  • Ensure you download the correct BIOS update: Only download a BIOS update from Dell if they are the manufacturer of your motherboard. Use the BIOS update file specific to your computer or motherboard model.
  • Visit Dell’s Drivers & Downloads page.
  • Select “Download & Install SupportAssist” to allow automatic identification of your computer. If this doesn’t work or you’re not on the computer you’re updating, search for your model or service tag and choose your computer from the list.
  • Choose “BIOS” from the Category drop-down menu.
  • Click “Download” to save the BIOS update file to your computer. If you’re downloading it on a different computer, save it to the root of a flash drive formatted with the FAT32 file system.
  • If the update file is on a flash drive, plug it into the computer needing the BIOS update and either turn it on or restart it if it’s already on.
  • If you’re updating BIOS from within Windows, open the downloaded file, confirm that the current BIOS version is older than the new version, and follow the prompts to complete the update. If updating from a flash drive, press the F12 key while restarting and select “BIOS Flash Update” from the options menu. Proceed to Step 8.
  • Browse for the downloaded EXE file on the flash drive, select it, and click “OK”.
  • Choose “Begin Flash Update” and confirm with “Yes” to initiate the BIOS update. Your computer will restart to finalize the update.

Updating BIOS on other systems:

For systems other than Dell, follow these general steps to update the BIOS:

  1. Visit the manufacturer’s website and search for their BIOS update utility. You can find specific instructions for ASUS, HP, Lenovo, and Intel on their support pages.
  2. Open the downloaded file.
  3. If the BIOS update is for a different computer, run the file and look for an option to create a recovery flash drive. Alternatively, copy the file to a flash drive and insert it into the computer needing the BIOS update.
  4. Follow the on-screen instructions provided by the update utility, which may involve pressing an “Install,” “Setup,” or “Flash BIOS” button.
  5. Restart the computer as prompted to allow the BIOS update to complete. Follow any additional steps if required, such as selecting “Update” or “Continue” buttons to finalize the update.

If you require specific assistance with BIOS updating, refer to the manufacturer’s help documents or support pages for detailed instructions relevant to their systems.
