I have a 2 year old BenQ S57 with HD4650m 512mb mxm 2.1 type II slot. Its had it. I need to either replace it or upgrade it. I don't know whether the BIOS supports upgrade and I would be happy just replacing it. But, I cannot find anywhere a replacement card (plenty of type A cards around but no Type II).

This is probably the best discussion of MXM inter-changeability I have found in a forum. Can anyone here help me with upgrade information, cards which will fit the slot and not throw out more heat? Or, a replacement HD4650 Type II?

Anything at all will help, I really don't want to scrap the machine because everything else is ok on board. Just the GPU.
