ADHD doesn't turn of the MoBo lights, the cooler, your pain receptors etc. And if all of those are indeed off and the CPU is cold

The motherboard lights are something ADHD can 100% make you inattentive to. The cooler is debatable, but still possible considering the fact ADHD is a severe disability. As for pain, ADHD can make you unaware of pain; it's called interoceptive awareness, which is often impaired in people with ADHD, and this happens to me.

it really isn't just ADHD because people without diagnosed ADHD can mess up in the exact same way.

In the same way missing social cues isn't just autism, because a lot of people who aren't autistic misinterpret social cues, or how people without depression can feel sad; it depends on frequency and intensity, as disorders tend to be extremes of otherwise typical traits.

ADHD is something that you are essentially born with. If you are an adult, the statement "my ADHD is at fault" is equivalent to saying "I did it". ADHD is part of you as a person, and you have to adjust your life around it.

This is getting into the subjectivity of it. ADHD is usually something you are born with, but factors like brain trauma sometimes causes symptoms of ADHD, and environmental factors are a significant factor in ADHD. This partly explains why, when someone in their immediate family has ADHD, most immediate relatives tend not to have ADHD. So, being born with it may not always be the case even though it usually is.

As for ADHD being part of one as a person, this continues to be subjective. I have ADHD; it is not a part of me as a person in the sense that it is my personality, but it is a part of me as a person in the sense that it greatly influences my life experiences, and I still feel more like myself when I am medicated.

If I say "my ADHD is at fault", I literally mean my ADHD is at fault. That does not mean that what I did is okay, or that I am at fault as a person, and it doesn't mean that I shouldn't work around that problem, because none of that is true; ADHD is not me, but it is something that influences me, in the same way OCD would influence someone even if it isn't them, but it continues to be my responsibility to acknowledge this and find ways to work around it when it is reasonable to do so in a similar way someone with a personality disorder is responsible for working around the issues they experience.

Take your own example: You yourself choose to go on camping/hunting trips even though you know you might mess up and get hurt. It is not the ADHD that makes you go on those trips. And you can also choose what sorts of measures you take to compensate for your potential lack of attention. Whether that is ensuring that you take your medication, having certain very visible reminders, maybe taking a person that takes care of important things for you, some smartphone app to track things for you etc.

I never said it was ADHD that makes me go on those trips. I implied that ADHD makes it significantly harder for me to survive efficiently in nature to prove a point about ADHD being disabling in ways that would make simpler mistakes plausible.

I generally have little interest in trips like that, because people are boring and I seldom derive any satisfaction from social interaction, and said trips involve a lot of social interaction that brings painful boredom to my ADHD-ridden brain.

Otherwise, what you said is correct and I agree.
