I had some graphics issues after running Bluestacks to run WhatsApp. The screen flickered until I shut down the app and I got worried. So wanted to verify my system using AHT.
I got a AHT .pkg package from an Apple forum thread to make Apple Hardware Test work on my mid-2009 MBP (no more AppleCare available) running OS X Mavericks. It used to run Snow Leopard - Apple staff upgraded to SL before giving me the MBP).
Apple mentioned that Snow Leopard normally ran AHT from the second CD, but I do not have that nor do I have a backup. I tried all options like command-D and D and even alt-D (they talk about these here as well), but none worked so I decided to go this path.
Now when I restart and press D I see a brief flicker and then my Macbook Pro turns off. Fortunately it still runs, but I want this to work of course. Why is this happening? Are these kinds of errors logged somewhere?
There are tools to access the EFI Bootloader and perform diagnostics, add partitions and so on using rEFIt as mentioned here on SO. I might give that a shot to see how it all works.
