I was going to mention the smell of opening a booster pack of trading cards! It was probably the same smell as opening a new video game and taking out the instruction booklet (back when they still printed those).
I've been around laptops which seem to be a health hazard. It makes sense they could expose users to harmful chemicals, since they're essentially a bunch of plastic and metals that get hot and have air blown over them into the room. Various flame retardants have been used in the past which have been phased out over health concerns, but manufacturers did this at different rates and many older machines manufacturered with various noxious chemicals are still in use. Who knows about what they use now (the last time I looked into this was c. 2013). TV sets have a similar history, as do space heaters and electric blankets.
As part of various health problems, I have some sort of high sensitivity to fragrances and cleaning chemicals. I had a roommate with a Dell that would make the room smell like ozone and plastic. I looked into it and Dell used various chemicals on those models that they later pledged to discontinue. I couldn't be in the same room as his laptop for more than 5 minutes.
