Hello i've a m5 581TG it's french version because american version and french version are not the same ! ^^ I've install ML 10.8.2 but i can't downgrade my bios to 1.07 (i'm in 1.11 version)  it make error  fan  turn maximum and laptop can't power off i most reset battery .

So have you got a method to full power off gt640m ?

 

Sorry for my very bad english !

Say me if you don't understand me

 

Thank you

French version has different model number search for it and then lock at acer web site for older Bios verison with bigger size than yours. Eg:(if 1.11=3 MB then you should find older version with bigger size 1.07=7MB) you might need even lower or maybe higher Bios version depend on size. you might ask why newer version is smaller? because the removed the option switching graphics which killed the ability to use MAC
