How to Check Your BIOS Version and Update It (2020)

Edited By Piyush, Reviewed By Shashank

What is BIOS?

BIOS stands for Basic Input/Output System. It is technically a firmware that a PC's microprocessor puts in use to kick life into your computer once it is turned on.

It is a pre-installed motherboard software that assists the system in controlling the built-in hardware of the system like hard drives, video cards, memory, USB ports, etc. 

BIOS is not something that you go about updating now and then. It is possible that before reading into this, you might have been unaware of something called BIOS. 

But, knowing BIOS and getting the latest version can significantly improve the performance of your system. This is especially important in cases of hardware troubleshooting or issues with RAM or a non-working CPU.

How to Check Your BIOS Version and Update It

Now, to update your BIOS version you need to identify the current version of BIOS on your system. This can help you judge how far you are from the latest technology.  There are many methods available to help you identify the current version of BIOS in your system and many ways to update it. 

Methods to Check Your BIOS Version

There are multiple ways you can use to check the BIOS version of your system. Some are independent of the operating system. Thus, they are suitable when the system is not functioning correctly. Others require your computer to be working to take help from the operating system. These methods are:

System Reboot

Rebooting your system is a traditional yet successful way to know your BIOS version. For this, you need to follow some simple steps:

  1. 1
    Reboot your computer as you might do on any occasion or cut the power supply and switch it on again. The main aim is to start the system again.
  2. 2
    Next, you need an observant eye to catch the BIOS version as your computer restarts. Most computers show a brand logo on starting up. The POST results are contained behind this logo. So, you need to press “Esc” or “Tab” to reveal the hidden POST information.

At times, you might not get ample time to catch hold of the BIOS version, and the screen might disappear too soon. In such cases, try pausing the boot process using the pause key on the keyboard. This will halt the process letting you check the BIOS version quickly.

Otherwise,  you can just take a  video of the screen while the boot process is happening. You can view it later!

Now, there might be too many cryptic letters and numbers, making it difficult to know what the version exactly is. If this happens, take a picture of the screen or note down all the digits and alphabets available. Luckily, amongst these digits and letters, you will find your BIOS version number.

However, as easy the method is, it is quite tedious and may take a few trials to get to the version!

Microsoft System Information (MSINFO32)

This program is a simpler way to find the BIOS version. There is no need to restart your computer. Plus, it is pretty easy as there is no need of installing newer programs of software. To use this method: 

  1. 1
    Go to Start and choose “Run.” If your system uses Windows 10 or Windows 8.1, then right-click and hold “Start” to choose “Run.” If you use Windows 8, find “Run” on the  Apps screen. For Windows 7 and prior versions, just click on  “Run” from the Start menu.
  2. 2
    Enter msinfo32 in the search box in the same manner. You will see the System Information window on the screen.
  3. 3
    Choose the “Systems Summary” option.
  4. 4
    Under the Items column, try and locate the title BIOS Version/Date.

The value against this title is the version number you are searching for. You can jot this down or export the data as a text file in the System Information menu. This is an effective method to check your BIOS version. However, it might not be available in all systems.

Command Prompt

Command prompt can be another easy way to get your BIOS version without having to restart the system. Use a straightforward command to identify the BIOS version in the command prompt. For this, follow the steps  below:

  1. 1
    Open the command prompt. If using  Windows OS,  enter “cmd” in the search bar of the start menu. Or else, you can execute a simple command 'WIN+R' in the Run dialogue box.
  2. 2
    In the command prompt, input  the following command and click  enter: 'wmic BIOS get smBIOSBIOSversion'
  3. 3
    You will see the BIOS version underneath the command.

You can also enter 'systeminfo | findstr "BIOS Version'  into Command Prompt to discover the BIOS version.

Third-Party System Information Software

In case the Microsoft System Information Software didn't get you the BIOS version information, then you may use some third party utility to find the BIOS version. There are several such tools, such as Speccy, much more efficient than MSINFO32. To use Speccy: 

  1. 1
    Third-Party System Information Software: In case the Microsoft System Information Software didn't get you the BIOS version information, then you may use some third party utility to find the BIOS version. There are several such tools, such as Speccy, much more efficient than MSINFO32. To use Speccy:
  2. 2
    Install and run the software. However, if you are using the portable version, then extract and run Speccy.exe or Speccy64.exe.
  3. 3
    Next, Speccy will take a few minutes to scan your computer. Wait a while as it happens.
  4. 4
    Open Speccy and choose Motherboard from the menu on the left.
  5. 5
    A lot of information appears on the screen. Locate and note the version listed against the BIOS subcategory. This is the answer you seek.

This method is effective and reliable but requires additional software to be downloaded.

Windows Registry

This is another excellent option to know the BIOS version of your system. The Windows Registry contains useful information including the BIOS version, motherboard maker, and motherboard model number. To access this information, follow these steps:

  1. 1
    Search and open the Registry Editor.
  2. 2
    On the left is the registry hive list. From this expand the “HKEY_LOCAL_MACHINE” option.
  3. 3
    Under this option, select “Hardware” followed by “Description” and then “System.”
  4. 4
    Under system, select “BIOS.”
  5. 5
    Within the list of registry values, identify the BIOS version on the right. The value against this will be your BIOS version number. Jot it down at an easily accessible location.

BIOS Updating Tools

You may not want to update the BIOS version often. However, when you do, it is useful to know the current BIOS version. You will use a special BIOS update tool for updating the BIOS version. This tool will give you the current BIOS version in the process of updating. Steps to use this method are:

  1. 1
    Locate the online support of your computer or motherboard maker.
  2. 2
    Download and run the tool.
  3. 3
    The BIOS version will be available somewhere in the tool even before updating the version.
