BIOS update for Aspire One AO756

eric212

Hello, I'm trying to find if there is a proper BIOS update available for my Aspire One AO756. I found the page on acer.com where the update would be, and there is one version that is newer than mine but it reads:

 

"Date: 2014/04/07 Version: 2.21: BIOS - UEFI for Windows 8 (not for upgrades)"

 I am currently using BIOS version 2.08 from 2012/11/06

 

What exactly does it mean when the newer BIOS version says "not for upgrades"? This PC came with Windows 8 but has been upgraded to Windows 10 ver 10.0.14393 Build 14393. I'm assuming this newer BIOS version shouldn't be used since my computer was upgraded to windows 10 but I just wanted to ask to make sure that was really the case. It kinda doesn't make sense to me because I'm already using windows 10 on the older (original) BIOS version.

 

Thanks for any info!

 

Eric

your laptop has 2.xx BIOS version so it's ok to update using any 2.xx BIOS version.

2.21 is good.

 

How can i understand which version i need to download?

Laptop versions:
1.xx can only be updated using 1.xx versions
2.xx can only be updated using 2.xx versions (normally 2.xx version are labeled "not for upgrades")
 
Desktop versions:
P01.xx can only be updated using P01.xx versions
P11.xx can only be updated using P11.xx versions (normally P11.xx version are labeled "*not for upgrades")

"L" BIOS versions are Linux OS dedicated (example P01.xxL)
 
* what does it mean "not for upgrades"?
During the windows 7 to 8 transition, some PC models had different BIOS versions from factory, related to the installed OS.
Windows 8 PC got an UEFI BIOS
Windows 7 PC got a "Legacy" BIOS

So PC with Windows 7 installed from factory can't use the "not for upgrades" BIOS version, even if they were upgraded to Windows 8 or 10, since the factory BIOS was a different version compared to PC with Windows 8 from factory.
