This article explains how to update the BIOS software for Windows computers. You rarely need to update the BIOS, and an incorrect BIOS update can completely disable your computer. Mac computers do not use the BIOS.
Download the BIOS update file
Open the Start menu. Click on the Windows logo in the lower left corner of the screen.
Open system information. Enter it in the Start window, then click System Informationmsinfo at the top of the Start window.
Check the model name of your computer. Next to the address “System model “you will see a list of numbers and letters. This is the model name of your computer. This information will be needed when searching for BIOS update files.
If you have a custom computer, skip this step.
Look for the BIOS version number. Next to “BIOS Version / Date “, after a moment you will see your company name, computer name and model number. The number after the period is the BIOS version.
For example, for a computer with the model number “Q553UB “and the BIOS set to version 202, here is ” Q553UB.202 “.
If you have a custom computer, you need to find the motherboard model instead of using the computer model number.
Open the BIOS manufacturer’s support site. Usually the easiest way to do this is to Google your computer manufacturer name, computer model name, and “driver ” or “BIOS “and then the appropriate link is to choose This process depends on your computer manufacturer, so you may need to click a few different links before you find the right one.
If you have a custom computer, you will need to find your computer’s motherboard name and “BIOS ” and “Updates “, then open the manufacturer’s website.
Locate the BIOS update file. Depending on your website, you may need to open the “Updates ” section first, “Support ” or “Download “or click the BIOS header. Once you have found the BIOS file, you can continue.
Again, this may involve some trial and error.
Make sure the update file is newer than the BIOS version. The file name should show the version number. If this version number is greater than the BIOS version number, the BIOS is out of date and can be updated.
If the version number on the website matches the BIOS version number, the BIOS is up-to-date and does not need to be updated.
Although the current BIOS version is an integer (for example, 301) and the site files are listed with a higher decimal (for example, 301.1), the location file is higher than the BIOS version.
Download the update file. Just click the download link, button or icon. After downloading the BIOS update file, you can continue with the BIOS update.
In some cases, you may be prompted to click on a file name to download it.
Most BIOS update files are downloaded to a ZIP folder.
Make sure your computer is plugged into a reliable power source. If the computer is turned off during the update process, it can permanently damage the BIOS, so use a reliable power source.
If you are using a laptop, be sure to fully charge the computer battery along with the laptop connection.
Extract the BIOS file. In most cases, you will need to extract the BIOS update file (or “unzip “) from the following folder:
Double-click the downloaded ZIP file to open it.
Click the Extract tab at the top of the window.
Click Extract All .
Click Extract when prompted .
Wait for the unzipped folder to open.
If applicable, read the readme file for the BIOS file. If there is a text document with the title “README ” or similar, double-click of it to open it and read the entire document before continuing.
If the instructions in the README file for updating the BIOS conflict with the instructions in the rest of this document, follow the README instructions instead.
Connect the USB flash drive to your computer. The BIOS update file must be saved on an empty USB flash drive, as the BIOS cannot access the files on the computer.
Copy the BIOS file to a flash drive. Click once on the BIOS file and press Ctrl+C to copy, then open the flash drive and press Ctrl+V to paste the copied file.
You need to leave the flash drive connected to your computer during the update process.
Enter the BIOS page . Restart the computer by clicking Start, then Power , then Restart, and then immediately press the key set by the computer manufacturer to enter the BIOS. If the BIOS does not turn on, you will need to reboot again and try another key.
On most computers, this key is a function key (for example F12,), but some computers use Dela key or key Esc.
If you don’t know your computer’s BIOS key, find it by entering your computer manufacturer name, model name and “BIOS key ” in the search engine.
If possible, back up your BIOS. If the main BIOS screen shows an option “Backup ” or “Save ” (or if you see a Backup tab at the top of the screen), select it and follow the onscreen instructions. This will allow you to reset the BIOS settings later if the BIOS update does not pair properly with your computer.
Conversely, you may be prompted to backup the BIOS when starting the backup process.
Not all BIOS pages allow you to back up your settings.
Enable and use the BIOS update tool. Since different BIOSes have slightly different methods of accessing the BIOS update utility, you may need to contact the BIOS manufacturer’s support site for brief instructions on how to do this.
In most cases, select the Boot tab , make sure the USB flash drive appears, enable backup or the “flash ” option in the list , then select the Flash boot option on the Advanced tab .
Pressing the BIOS key with a USB drive connected sometimes brings up its own menu where you can select upgrade options and follow the on-screen instructions. This is common with Dell computers.
Allow computer BIOS update. This process can take anywhere from a few minutes to an hour or more, depending on the depth of the computer and the BIOS update. After the BIOS update is complete, you may be prompted to confirm this decision, but you will need to restart your computer.
Do not turn off the computer while updating the BIOS. Doing so will damage the BIOS and prevent the computer from starting, completing, or running BIOS setup.
