Updating a bios
To update the BIOS on ASUS systems, you will have to use the Win FLASH Utility. In a nutshell updating the BIOS is a pretty straight forward process considering that you get the model number right.
In fact, most of the recent Windows versions like the Windows 10 handle the update process in a much more elegant manner as opposed to lets says Windows XP systems.
Visit the manufacturer’s site to download the BIOS update, for instance, if you own a Dell laptop you can head over to Dell.com, or you could use Dell Update Utility.
Identify your product by entering Service tag or serial number.
Well, in case you own a Lenovo laptop the best way to update the BIOS would be to use the Lenovo System Update which is supported on Think Pad, Think Centre, Think Station, Lenovo V, B, K, and E-Series.
