There is a difference between those instructions and those used for Internet recovery. Computers that do not support Internet recovery must invoke AHT differently. The oldest Intel models have to use the installer disc that came with the computer in order to invoke AHT.

I can understand that. Is there any definitive list of key shortcuts at startup which would include Lion and Mountain Lion? I am assuming that KB HT1533 might not be up to date. Also, other peoples have mentionned Cmd-D.

The above documents what keyboard shortcuts are used to invoke AHT and some added functions in Lion and/or Mountain Lion.

I am looking for a hardware test not recovery for OS it seems not even Apple communities knows the difference.

Thanks! Oh my. Alt+D worked for my 17" 2011 Macbook Pro that came with Lion. D and Cmd + D did not work.

Huh... that's what Cmd+D/Alt+D/D gets you, a hardware test.

Rastikan is right.
My MBP 17 (late 2011) would not boot to AHT by holding D key alone.
Instead: Hold the ALT (aka Option) key along with the D and it starts "Internet Recovery Mode" which loads AHT. Very misleading as I did not want to do a system recovery, and that is what it appeared was going to happen. It did not.
