I have a surface book 2 and my power supply is no longer working. The power was the 44w power supply. So my question is it ok to buy the 64w or 127w power supply given I can't find the 44w power supply? Will it damage my surface book? Thanks

Either the 65W or the 127W (or even the 102W if you can find it) will be fine with the non GPU original Surface Book - there is circuitry and firmware that prevents overcharging. Be sure to get a genuine Microsoft Surface charger and not a 3rd party one.
