Apple HardWare Test On Lion OS X
How do you perform this?
iMac, Mac OS X (10.7.1)
Insert install DVD for Mac and boot with D depressed.

A DVD isn't needed, I just need to figure out what to press during startup for hardware test.
Just got off the phone with Apple.
On my 2011 MacBook Pro (shipped with Lion) hold down Option + D during startup. This will force Internet Recovery (spinning globe logo). After a few minutes Apple Hardware Test will begin.
The following link is just flat WRONG, holding only D does nothing:

It works fine if the machine did not ship with Lion. Because your machine shipped with Lion obviously that link wouldn't work. If I recall correctly the OP's machine did not ship with Lion. He's posted many times about many things.

OK, well, one by one shall we?..
Holding D during startup DOES NOT launch AHT on a roommates 2011 MBP 2.2Ghz running 10.7.2 that shipped with 10.6.8.
That link is for "Intel-based Macs", not "Lion Shipped Macs" so obviously it DOES apply to my machine. Furthermore, if you read, it specifically states:
"2. Press and hold the D key before the gray startup screen appears. An Internet-enabled connection via Ethernet or Wi-Fi is required to use this feature. Note: Some Macintosh computers that shipped with OS X Lion support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT."
BUT in order to do this you must hold Option + D during startup, which that link does not say.
The problem is this,
The Internet Recovery firmware update for the early 2011 MacBook Pro was released on Sept. 14th
BUT
the article was last updated a week earlier on Sept. 7th

Apple needs to update this info!
Hold Option + D during startup for Apple Hardware Test
I agree. I've been having problems with my i7, August, 2011, iMac, shipped with Lion, and a screen that instantly goes completely black for no apparent reason (I can hear the computer running "under" the black screen but pushing buttons does nothing to restore the screen). I wanted to run the hardware test, but holding D did nothing. I tried over half a dozen times. With the "Option-D" keys, it worked the first time. (BTW, the hardware test revealed no problems; the black screen somehow seems connected to my external backup drive; weird.)
