fyi.
The ASUS global site has different articles about this issue for motherboards and system products, so for the G20AJ (which isn't listed at this page yet), you may want to keep an eye on this page below, or the general news page if a new article is released about it. Thanks.

We may just want to keep an eye on those sites though to see if anything changes later.
