How to update BIOS on a Lenovo laptop

Once again, a standard instruction, since Lenovo also provides its customers with a standard installer for installing the updated BIOS version:

1. Go to support.lenovo.com and find your device in the search bar.

2. After this, we go to the driver and software download section, where we set the search filter to the required OS values ​​and the desired category of files to download.

3. Then download the files found for updating.

4. We carry out the installation according to the instructions of the automatic installer, and then reboot the device.

Nuances of installing updates

Before updating the BIOS, you need to know a number of nuances:

• You should always choose the latest version of the update, because problems that arise in the operation of certain devices can be eliminated by installing a version an order of magnitude higher and no more (determining the current version will be discussed below);
• if the update is necessary to restore the operation of the laptop (there is no access to the OS desktop), then you can use the standard installer only after access has been restored via a bootable USB flash drive or disk (the traditional option is Windows Live CD or analogs).

Checking the BIOS version

The check can be performed in two main ways:

1. You just need to go to the graphical interface when the device starts up and find the necessary information in the main menu.

2. In Windows, just use the key combination “Win” + “R” and enter the phrase msinfo32.

3. In the window that opens, select the “System Information” sub-item, and then study the desired item.

After receiving this value, you can begin updating using the method described for devices from a specific manufacturer.

Updating the BIOS is not a complicated process, but it requires some care from the user. Only if you follow the basic instructions can you achieve the desired result: eliminate the main problems that have arisen due to the obsolescence of its version. It is best to entrust this procedure to a specialist who can conduct diagnostics and understand whether the BIOS is really the cause of the inoperability of certain OS components.

Conclusion

From the examples discussed, it is clear that updating the BIOS is not a difficult task at all. But when updating, you need to be extremely careful and not allow the computer to turn off during this process.

I would also like to remind our readers once again that under no circumstances use BIOS files for firmware from unofficial sources, as this can lead to breakdowns and you will have to restore your computer at a service center.
