No momento desta postagem, 1,25 é a versão mais recente. Você precisa fazer o downgrade para 1,15.
O processo está detalhado aqui: link
Aqui está no caso de o link ficar inativo:
Go to: http://us.acer.com/ac/en/US/content/drivers
Search by Product Model:
Aspire E5-573G
Select the right OS and download a bios. In my case I downloaded 1.15.
Run the ZRT_115.exe.
It will fail.
But before you close the installer, go to C:\Users\name\AppData\Local\Temp\
Search for a folder (random letters).tmp
There should be a H2OFFT-W.exe and zrt.rd file in there.
Just copy this folder and close the failing install.
In that copied folder, edit the platform.ini file.
Before:
[BIOSVersionFormat]
;[nb4-version] +
BIOSVFEnable=1
VersionFormat=XN.NN
After:
[BIOSVersionFormat]
;[nb4-version] +
BIOSVFEnable=1
VersionFormat=XN.DD
The VersionFormat value now has 'XN.DD' instead of 'XN.NN'.
This will ignore the fact that 1.25 -> 1.15 is a downgrade.
Prepare for a reboot. I.E. close unnecessary applications. Because it'll happen automatically after running the installer.
Run H2OFFT-W.exe.
Upon reboot, you'll see a bios installing progress bar.
After that is done, press F2 during startup to get to bios. The version should now be 1.15.
