Q: upgrade to El Capitan and wanted to use AHT
I have a Macbook Pro running 10.7.5 and wanted to upgrade to El Capitan. I got a reply and part of it stated to shutdown, restart and hold down the d key to get AHT to run and check for hardware issues before I upgrade. Well, I did that and I finally got a series of bongs. I released the d key and my macbook pro restarted. So, how do I get to AHT?
MacBook Pro, Mac OS X (10.7.5)

Depending on the age of your Mac, it may not exist as a partition on your disk. In that case it would be on your OEM install DVD.
