"Vintage" desktop BIOS updates

[barryC2120]

My 750-114 desktop has always run fine, but I just found out that numerous BIOS updates are available for it. Can I assume that these updates are not critical or should I update?  If I should update the system, should I just use the "newest" update (2018) or should all the updates be done in date sequence?

Thanks in advance... B>)

Hi:

Below is the link to the product specs for your PC.

HP ENVY 750-114 Desktop PC Product Specifications | HP® Customer Support

It has the Odense motherboard which has a SSID of 2B47.

The only BIOS update out of the 5 listed on your notebook's support page that will work for your PC is this one:

Driver - HP ENVY Desktop - 750-114 | HP® Customer Support

What I recommend you do before considering updating the BIOS would be to read all of the release notes for the current and previous BIOS updates HP released for your PC.

Those updates are listed when you click to expand the Revision History section on the above link.

BIOS updates are cumulative, so the latest update will include any fixes or enhancements the previous ones included.

One very important note:  If you update the BIOS to the latest version, you will not be able to go back to an earlier version and that can be said for several of the other older updates.
