ASPIE TC-780 AMZi5 bios is A01 2016---- Should I update?

2inSD

Hello People!
I have a question RE: bios updates aka firmware for a Acer ASPIRE TC 780 AMZi5.
My current bios is AO1 2016. 

THERE are several bios updates noted in my support for this model under my serial no.
Do I need to apply all those? or just the most current one?
OR NONE at all.
I guess my concern is the security flaw in the processor (ME?)

Thanks for the help.

RO2-B2 is the latest for the TC-780 (not A)

If your machine works fine, you do not have to update the BIOS. If you want to, take the latest version.The versions are cummulative.

In case you're interested in BIOS updates concerning Meltdown and Spectre for your model, refer to this site:

https://community.acer.com/en/kb/articles/10435-meltdown-and-spectre-security-vulnerabilities

If you have BIOS R01.XX, you can only flash to R01.XX. If you have R02.XX, you can only flash to R02.XX. Not possible: R01-XX to R02-XX.

Example: R01-A1 to R01-C1: ok, R01-A1 to R02-C1: not ok.

In other words, if your current BIOS is R01.A1, you have already the latest version.

Take care of this!

Open cmd as Admin and enter 'wmic bios get smbiosbiosversion' and you see your current BIOS version.
