I think that this bug cannot be resolved until ASUS opens its information
about ACPI implementation particularity in this laptop model or
disassembling windows ATK driver code. IMHO there is a hardware or BIOS bug
and ATK driver mitigates it but only in Windows. The only thing to do is to
ask ASUS
I confirm this bug. Same symptoms on my ASUS A7J.
I spent a huge amount of time trying hard to dig and solve this problem.
Suspend to ram did not worked neither on 7.10, 8.04 and 8.10 nor on some other
linux distributions such as Mandriva and Fedora.
