Updating a bios in windows vista
Identify your product by entering Service tag or serial number.
That being said the update procedure might vary slightly from product to product.
Your boot CD/DVD may or may not help depending upon how the BIOS stands after a powercut or a sudden system turn off while rewriting the BIOS.
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.
Make sure “Drivers and downloads” is selected on the left.
Scroll down, under “Optimize your system with drivers and updates” and click “Find it Myself”.
BIOS is a term we have heard from quite sometimes, in fact, it’s possible that for most of your hardware issues the IT guy may have suggested a BIOS upgrade before troubleshooting the hardware. BIOS is an acronym for (Basic Input Output System) and is a piece of software that goes along with the PC’s motherboard.
In case of laptop, make sure the battery is present in the laptop and the AC adapter is connected with it the whole time. 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.
