No I don't feel bad... just dumb and old.
It happens much more often than you might think. I had a Dell years ago, and I used to get annoyed whenever I called India and they asked me to double check if the computer was plugged in and turned on.
I've heard a lot of "tech support" stories since then that make me understand why they ask that.
I have a lifetime of experience in IT and spent several years as a support tech. I lost count of how many times simply making sure it was plugged in or turned on solved the problem. Funniest one was back when I was a day-to-day help desk tech and a call comes in about a PC issue. Call should've never came to me, I was L2 software support at the time, but L1 sent it to me because they didn't know where else to send it. I'm asking the user, a woman probably in her late 40's to early 50's what's going on, what does she see, what lights are on, etc. Eventually, I figure out that this computer isn't plugged in and each time she presses the power button nothing happens. I ask her to check the back of the PC and find the power cable, then follow it to the wall. She says "Oh...oh. umm..." The universal sound of "I found the problem and it is so blazingly stupid I want to stick my head in the microwave and give myself a tan." I can tell she's embarrassed so I tell her to "give the cable a jiggle. Sometimes jiggling it helps." She's all excited and going "yeah, yeah, let me try that. Hey, jiggling the cable worked, the computers coming back on." Sent her on her way, closed the ticket, and laughed with my fellow techs for a few minutes before the next big problem came to the desk.
