How to Update the BIOS of a System

Hardware updates are not as common as software updates. But when some issue arrives in the hardware of a laptop/PC, the manufacturer tries to resolve that issue by releasing the BIOS update. That is why tech-savvies recommend updating the BIOS of a laptop/PC to the latest version. However, if you don’t know how to do that, then we have got you covered.

How to Update the BIOS Version to the Latest? (Title Image)

What is BIOS?

BIOS stands for Basic Input/Output System. BIOS firmware handles the initialization of the system’s hardware during system booting. Apart from hardware initialization, this firmware also supplies the run-time services to the operating system and its programs.

Why Should you Care about Updating the BIOS?

Computer experts recommend updating the BIOS of a system to the latest version because the updated BIOS will allow the motherboard to identify the new hardware perfectly. Plus, BIOS updates will remove the bugs and increase the system’s stability. Hence, it is necessary to download and install the BIOS updates whenever available.

Steps for How to Update the BIOS

The procedure for updating the BIOS of a system is almost the same for all manufacturers. There might be a few differences but you can get around them by Googling your hardware.

Some Prerequisites

Before starting the update process, keep the following things in mind:

  • Make sure that your laptop has at least 10% battery.
  • It’s better to plug in your laptop with a power source instead of running out of power during the update process.
  • Back up your data because if anything goes wrong during the BIOS update, you will at least have a copy of your data.
  • If you are using BitLocker encryption on your hard drive, you will need to suspend BitLocker encryption. You can get more information regarding this on DELL Knowledge Base. We recommend doing the same for your laptop’s manufacturer.

Now, let’s start the BIOS updating procedure.

Note: You can either download the official support assistant of your laptop’s manufacturer or use the manufacturer’s website for updating the BIOS. For this example, we are using the official website
