BIOS (Basic Input Output System) introduces the operating system (OS) to your computer or laptop. BIOS is one of the most important components of your system that helps computer communicate with the hardware devices. It is usually located on a small chip placed within the motherboard of the system and provides the computer important information when the booting process begins. BIOS settings need to be right and as per the requirement otherwise the system will not be able to function properly.

Changing the BIOS settings is important and beneficial if the OS installed on your system is not able to communicate with the hardware devices on your computer. To help it interact with the hardware devices properly and without any hiccups, you need to revise your BIOS settings. It happens because the BIOS system is not the same for all the versions of OS and it varies with the different versions. Changing the BIOS setting is not a very difficult task to perform but if you take a wrong step then it can become counterproductive. The chances of error can also be minimized by considering certain important things while changing the BIOS settings on your laptop.

In this article, you will get to know about the 3 most important things that you should keep in mind while changing the BIOS settings:

Take a backup of CMOS memory

Unlike other settings the settings of the BIOS are not stored on the system memory hard drive. Instead, these are stored on CMOS Memory. This is a special reserved memory to store BIOS settings. As CMOS is backed up by a battery so there are chances that if the computer is turned off or unplugged the settings can also be lost. It is advised to take the backup of the settings so that even if the battery malfunctions or the system is turned off, the backup remains intact to enable easy restoration of the settings.

Maintain a record of the changes made to the settings

It is a good idea to maintain a record of the changes that you are making to the value of the settings. By having a record of values you can use the previously used value to run your laptop if the new value fails to produce the desired result. In case you have not noted the value then you won't be able to use the one that you have previously entered.

Must have the basic technical knowledge

The BIOS setting is responsible for maintaining various important things on your laptop including:

• Time and date • Virus protection warning • Information related to basic video mode • Information related to energy-saving • Information of port settings and more.

Thus it becomes important that you begin changing the settings only if you know the right procedure. In case you fail to do it in the prescribed manner it is going to create a lot of troubles that may complicate the issue even further.

If your laptop is giving you problems related to BIOS settings then consulting an experienced computer support service provider for instant resolution of such issues is the best option. Technicians can give you the best online resolution of tech issues related to BIOS.
