I purchased a Surface Pro 7 bundle back in Feb from COSTCO. It stopped charging using the Microsoft Charge. It would charge using USB but not the charger it came with or with one I had in hand from my SP4.
I contacted the COSTCO Concierge service to see my options. They put me in touch with Microsoft support and I was sent a new charger. When I tested the new charger, I had the same symptoms. Called COSTCO again and went the same route with MS sending me a replacement charger (#2). I also purchased a third-party charger on Amazon because I was going away and did not want to be without a charger. The Amazon charger arrived 1st and it worked fine — interesting.
when the 2nd charger arrived – I tested it and it too did not work so I started to suspect the problem was with the SP7. I again called the Costco Concierge service, and this is where it got interesting. Microsoft went to online support and did not answer calls from even Costco. Costco gave me contact info (phone and URL) and when I tried to get support, it reported my warrant had expired in October while I was trying to get this resolved.
The bottom line is the warranty date was when Costco was delivered the SP7s AND Costco failed to update the sales date. It took three calls to Costco before over 2+ weeks to succeed in getting in touch with Microsoft and getting the date reinstated and getting a replacement SP7. The charger I received from Amazon was one for the Surface Book – it was 127W. The SP7 charger is 64W.
I now have a new SP7 that charges with ALL my SP chargers, a Warranty through Dec 2022. While the outcome was good – it was crazy hard. I really do not know how I would have succeeded if not for Costco because the only path open with MS was to pay for support because I saw no way to contest the sales date. Alls well that ends well I guess!
