Where to find BIOS changelogs?

HP Recommended
HP Spectre x360 - 15-bl012dx
Microsoft Windows 10 (64-bit)

Where do I find the software change logs for the BIOS updates? 

(Another post suggested a "related files" area, but I didn't see that.)

For example, I want to make sure that the update doesn't include the Speculative Execution 'fix' that would slow down my laptop, and see what bugs have been fixed or device-support added, etc.

(In this case between F.04 and F.04-RevA.

thanks

@thelazydogsback Welcome to HP Community!

 

I understand that you are looking for the BIOS changelogs.

 

The BIOS is just a set of instructions for basic input output operations.  It does not store or keep track of files, locations or history of any kind.

 

The only thing I can think of you are meaning is from this link.

 

Viewing BIOS Event Logs

 

Now some BIOS have a tab that will let you go in and clear this log but if there is no tab then there is no option.  

 

What would you need to clear the log for?

 

If you are having hard ware issues or bios issues and only if you are having issue then you can refresh or flash your bios.

 

Here are a couple links  for you to check out.

I think you misunderstand -- I'm not looking for "logs made by the BIOS", I'm looking for the list of feature changes made to the BIOS between versions.

thanks
