Updating the laptops bios software
Computers are now coming with UEFI firmware instead of the traditional BIOS, but the same is true for UEFI – it’s low-level system software with a similar role.

If you have a modern laptop, you’ll have to press the Lenovo key to access BIOS menu while your laptop is powered off, which is usually besides the power button on the front.

Manufacturers often release updates to their computers’ BIOSes.
If you built your own computer, a BIOS update would come from your motherboard vendor.
