He's been using it for school work - prefers to sit at his desk in his room to use it. 4x this week I've asked him to bring it downstairs but no, I find it slung on the floor by his desk because it was "taking up too much room".
There's no battery in it, he hasn't seen it and apparently I'm being unreasonable to blame him for it.
He's Autistic (mainly affecting his emotional regulation) so he's had a massive meltdown and blazing row over it which normally happens when he's been caught out - for lack of a better term.
He has his own room which none of us go in unless he's there and his sister can't use the laptop without help so it can't have been her either 🤔
