Experiencing somewhat of an oddity with a brand new Acer laptop (Model #5560G-SB448). Has AMD Quad CPU (A8-3500).
Replaced stock Western Digital HDD (750GB 5400RPM) with a new 500GB Seagate Momentus XT (Hybrid SSD/HDD).
BIOS detects both model and serial number. Using retail copy of Windows 7 Ultimate DVD, each and every time the OS attempts to initiate a shutdown, Windows hangs.
So tried MSDN copy of W7 Home Premium 64-bit and Momentus HDD, same problem.
Ghosted original stock OEM HDD, wiped partitions and tried installing Windows again. Both copies of Windows hang on shutdown.
Here is where it gets stranger, if I manually initiate shutdown after hang, upon reboot, OS continues install as if nothing happened. I can get Windows installed using this manual shutdown method BUT regardless of driver and Windows update, it will always hang on shutdown. As an FYI, have also updated BIOS and chipset drivers.
Replace HDD with ghosted image, initiate the eRecovery process and everything runs fine. HDD manufactuer doesn't matter; just how you load Windows does.
Thinking it was hardware-related, took laptop and replaced it with new one. Same thing happens.
Have opened ticket with Acer BUT I was hoping for your thoughts or feedback.
