Found out that the high wattage charger for surface books with dGPU doesn't work anymore and only the lower wattage ones do. The store confirmed that it needs replacement. I don't really want to get it replaced since the hassle of downloading everything again would be a pain. Has anyone used the lower wattage chargers to see it only charge slower, rather than trickle down on charge when doing heavy tasks? Also, I hear that getting replacement devices are refurbished and chances are I might get a worse working device than the one I currently have? Is this true?
