Power off when updating bios


If you get a BIOS for another piece of hardware – even a slightly different revision of the same motherboard – this could cause problems.BIOS flashing tools usually try to detect whether the BIOS fits your hardware, but if the tool attempts to flash the BIOS anyway, your computer could become unbootable.The BIOS is low-level system software that should “just work” without getting in your way.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.You likely won’t see the difference between the new BIOS version and the old one.In some cases, you may even experience new bugs with a new version of the BIOS, as the BIOS that came with your computer may have gone through more testing.If you built your own computer, a BIOS update would come from your motherboard vendor.



Computers should ideally have a backup BIOS stored in read-only memory, but not all computers do.Given that you probably will not see any improvements from updating your BIOS, that new bugs could pop up, and the potential for errors while flashing, you shouldn’t update your BIOS unless you have a reason to.Here are a few cases where updating makes sense: Be sure to check the change log for the BIOS updates and see if they actually have an update you require.BIOS updates typically have very short change logs – they may fix a bug with an obscure piece of hardware or add support for a new model of CPU.
