    We had one nasty storm in my area last night and I unplugged my imac to prevent lightning from striking it. However sure enough lightning struck and got another device on my wired network.

    So not only does that device no longer work, but my router/modem combo is unable to connect to my dsl connection. So I have replaced it with a spare modem/router combo my isp gave me a while back.

    However here is my problem, while I did actually unplug my imac from the wall, it was still connected to the router via Ethernet. In the past if lighting would get the router it would usually take out the Ethernet port on the computers and devices attached to it.

    But it looks like I lucked out this time since the Ethernet on my new imac appears to still be working fine. So I am guessing that lightning somehow got the device and the router absorbed all the collateral damage.

    However I would like to run the Apple Hardware Test just to make sure everything is up and running. Does anyone know how to get to it on the mid/late 2011 imac?

    BTW I had all of my devices on a fairly high ranking Phillips surge protector. So I don't know how lighting keeps freaking getting my stuff. Its almost like its traveling through my house itself somehow :(

    The house of a friend of mine was struck by lightening a couple weeks back. Every device in the house which was plugged into a socket was fried. Amazing thing is, that the two iPads, two iPhones and one macbook pro which weren't plugged in at the time but just lying around. the iPads were on the couches, MBP in a bed and the iPhones on the kitchen table. Well those devices weren't fried but they al started acting up. Shutting down randomly, doing stuff themselves. Really weird. They brought them to the apple store and they had to be replaced because something was broken in all of them. Pretty amazing considering that they weren't directly affected by the lightening through cables but through air or whatever else conducted the electricity.

    I would like to know how to get to the hardware test myself :D Best of luck to you with your devices, Sorry to hear that happened to ya :(

    To get to the test on the 2011 iMac that came with lion just simply hold down

    Option + D

    and turn on the machine while holding down the key combo.

    Its really sad that it took this long for me to find out how to do it, most help articles just say to hold down D during boot. Which does cause the boot to take longer, but it doesnt put the mac into test mode. Last night I finally found a post that suggested holding down option AND d, and what do you know... it works!

    Basically the computer will boot into internet recovery, or appear it is, then boot into the hardware test. :D

    Anyways I did a quick test and a extended test and both passes with flying colors. So I guess I lucked out :D!
