So, I've got my RMA label and am all ready to wipe my machine and send it back... But here's the thing. My machine is mostly working awesomely, it's all set up how I like it and some of the software is going to be a pain to get again. Also I know I'll be getting a refurb machine in return and am a bit concerned about that. So I'm currently weighing up my options. My issues for returning are: 1. A faint yellow line down the side of the screen. This is pretty faint and if it was the only issue I'd be able to live with it. Also I'm not even sure they'll be able to see it when I send it back as only some of the forum users here can actually see it in posted photos, so I'm a bit concerned they won't see it. My husband can barely see it and my kids can't see it at all. 2. Tingling on the back when charging. This is an issue if it affects safety. I posted a thread on this and advice ranged from it's normal to change it now it's dangerous. I'm not really sure what to do. If it's normal especially here in Australia a new unit will probably be the same. If it's dangerous then, of course, I want to change it. I use my surface on my lap a lot so I'm usually using it when it's on charge, I need to know this is safe. So what do you guys advise, should I change it and hope for the best in refurb roulette or should I hang onto this one with its added 'features'? Many thanks for any replies.
