Just to let you know I apparently have exactly the same issue with the same
laptop. If it can help, I could try installing the M$ Student Edition during
the weekend and report the results.
Windows Server 2008 64-bit, fresh GPT partition table will be my lab
environment. Standard installation procedure.
I am running Ubuntu 12.04 with 3.2.0-18-generic.
