I  just updated the new bios 2.18, it dose improve the cooling performance but decrease the performance of graphic, I got some lag now when running some software or games, but 2.15 works good. maybe its a balance of performance and cooling, but is there any way to roll back 2.15? 

if someone want to update but prefer performance, I dont recommand to update.

Hello zxcom2000,

You can roll back to the version 2.15. You must flash the bios with this version. This is the same way to upgrade or downgrade.

Hi 

Thanks for your reply, but I cant downgrade, it said I can only flash new version of BIOS

Hello,

Have you tried to flash it under MS-DOS?

Look the folder ME (Management Engine of Intel).

Read the file read.txt

thanks, I understand its a good way to install under ms-dos, but dont know how to do that

Hello,

I went too fast...

fptw64.exe is the Windows 64 bits version of Flashing Programming Tool.

So you can't use under DOS. The DOS version is fpt.exe.

You may demand a DOS version to Acer support (Tchat)... Perhaps it exist.

Hello,

Read this Intel document about "Instructions for BIOS version downgrade"

Thanks and regards,
