BIOS updates can be issued for a variety of reasons. They can be as trivial as correcting a spelling mistake or adding eye candy as well as important updates addressing bugs or adding further functionality.
However, the issuing of a BIOS update should not be seen as mandatory. Unless you have a problem that is expressly addressed by the update or it includes functionality that you simply can't live without, then I would recommend you leave well alone (although the choice is yours of course). 'Serious' BIOS software developers will always list major or important revisions. Not mentioning the revisions can mean one of two things, the change is of no functional consequence or the issuer is incompetent! (I'll say no more!!)

I have mentioned this before - The BIOS plays NO part in the operation of your operating system! It is a very common misconception that the BIOS plays the part of a 'driver' within Windows - it doesn't.
My reference to 'bricked' is directed at the many occurrences of failed BIOS update attempts. These are not generally the fault of the BIOS code rather the result of an incorrect or incomplete update procedure. (In reality there is no such thing as a bricked laptop - they can all be recovered with the correct tools.)
Modern or older, UEFI or not, they are all equally susceptible to update failures.

Hey guys, I need help fast. I have a z575 laptop. Yesterday I got a update from Windows update, abuot my wireless LAN card. I did the update and ever since then wifi is not connecting, it says 'Windows cannot connect.' I have reset my router, but wifi still dosent work. I have also downloaded the. Nov 21, 2013 According to Intel's documentation, my processor (Intel Core 2 Duo E7400) supports VT-x, but I don't see an option to enable it in my BIOS. I checked Dell's 'Update Drivers' page, and they list PHOENIX BIOS 1.0.1, which is actually older than the version I have installed (1.0.7).
By 'upgradeable', I refer to your laptops ability to run Win8 or 9 or 10... Install the Win7 BIOS and you limit your OS upgrade options in the future (unless you risk writing a new BIOS yet again).
That said, should you elect to install another BIOS just ensure you get the right one and that you are clear on the correct update procedure before you start! With any luck you will avoid that sickening feeling of staring at a black screen!
