Hi! Will you be in Dubai? I've been several times, to visit my husband when he worked in Afghanistan. Very cool place, but the air quality is not like you see in the pretty blue sky travel advertisements...
So, I wouldn't take away his laptop. I'd instead use it as a reward for him to earn after he does some sort of minimal helpful things around the house. Such as after you take out the garbage and vacuum, you get an hour on the laptop. Variations are fine of course depending on how much time you think he should get, how much work you think he should do (don't go from no chores whatsoever to he suddenly has to clean the whole house every day! ) and what sorts of chores he'd do well at (like some kids don't like the noise of the vacuum, are terrible at folding towels, don't want to work independently alone in a part of the house, whatever.)
As it stands right now, my almost 12 year old son has spent maybe a grand total of 45 minutes alone in his room, total, in his whole life. He is afraid to be alone. It can be exhausting for me! Him too I'm sure. So if you envision the total opposite of what's bothering you about your kid at the moment, then that can help you feel a bit better about what he's actually doing. I just put a TV in my son's room a week ago with the hope that it would encourage him to spend some time in there alone, but so far, not as much as I had hoped, but he has probably accrued 40 of the aforementioned 45 minutes just in the last week. LOL. Still not as much as I was hoping for, but I'm sure at some point he will not want to spend every moment with me... I think...
take care!
