'We lose money on replacing the entire motherboard for 3 cents under cost whenever any minor thing goes wrong but make bank on refurbished computers with a single resistor that had gone bad which we get for free for some reason'

Well, repair is included in the hefty price tag. Anything else about this is just noise.

I don't know why you're being downvoted, manufacturers include warranty costs in their cost bills to determine final sale price.

You've got really no way of knowing that for sure. Could just be a hefty price tag that doesn't include repairs.
