Purchased this a couple weeks ago. First off it arrived in some kind of Amazon recycled cardboard box instead of Microsoft's original retail packaging. Couldn't really tell if this is brand new though. After initial setup I noticed the battery always stays at 0% even when plugged in. Left it plugged in overnight and it's been 0% ever since. Obviously the battery is defective.Then I requested for a refund. As I live overseas I'd need to ship it back to the seller, which is a third-party seller in Florida BTW, meaning I have to ask the seller to reimburse the shipping charges, as opposed to having Amazon doing this for me. It turns out I have to pay some USD$200 to ship it back first and chances are I may not get reimbursed at all as the seller doesn't seem to think they have to pay for it. After some chatting Amazon service reps don't think it's their responsibility either and keep asking me to ask the seller to pay for shipping or ship it back first then claim reimbursement later, which I doubt will ever happen.I also reached out to local Microsoft asking about getting a replacement. They were helpful but also made sure to let me know that any replacement won't be a brand new machine. So I'm kind of stuck here not knowing what to do next. Pissed, obviously. This is why I'm writing this review.BTW upon checking the serial number MS says my machine is enterprise bulk purchase model, not a retail one. Not sure if this info matters at all but though you might wanna know.
