Skip this step if you have a custom-built computer.
For a computer with the model number “Q553UB” and a BIOS set to version 202, for example, you would see “Q553UB. 202” here. If you’re using a custom-built computer, you’ll need to find your motherboard’s model instead of using the computer’s model number.
If you’re using a custom-built computer, you’ll need to look up your computer’s motherboard name along with “BIOS” and “update” and then open the manufacturer’s website.
Again, this may involve some trial and error.
If the version number on the website matches your BIOS version number, your BIOS is up-to-date and does not need updating. Even if your current BIOS version is a whole number (e. g. , 301) and the file on the site is listed as a higher decimal (e. g. , 301. 1), the site’s file is a higher version than your BIOS uses.
In some cases, you may have to click the file’s name to prompt it to download. Most BIOS update files will download inside of a ZIP folder.

If you’re using a laptop, your computer’s battery should be fully charged in addition to the laptop being plugged in.
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 extracted folder to open.
If the README file’s instructions for updating your BIOS contradict the instructions in the rest of this article, make sure you follow the README’s instructions instead.
You need to leave the flash drive plugged into your computer for the duration of the update process.
For most computers, this key is one of the function keys (e. g. , F12), though some computers use the Del key or the Esc key. If you don’t know your computer’s BIOS key, look it up by typing your computer’s manufacturer name, model name, and “BIOS key” into a search engine.

You may instead be prompted to back up your BIOS once you initiate the backup process. Not all BIOS pages allow you to back up their settings.

In many cases, you’ll select the Boot tab, ensure that your USB flash drive shows up, enable any backup or “Flash” options in the menu, and then select the Start Flash option from the Advanced tab.

This is common on Dell computers. [2] X Research source
Do not turn off your computer while the BIOS is updating. Doing so can cause the BIOS to become corrupted, meaning that your computer will be unable to start, complete the BIOS installation, or otherwise run at all.
