Microsoft Surface 3 ROW Charging Issue

Hi,

I have a brand new. yet ancient Microsoft Surface 3 ROW which I have been using for college for some time with no problems until I installed Windows 10 Professional and noticed that whenever I plug in the device and have it switched on, it will say battery% (plugged in) yet not charging... I have noticed it will charge if the device is switched off and left over night and will be about 90-100% by the morning. I take it to college and use it plugged in and noticed that the battery discharges even though connected to the mains...

I have tried a hard reset and some other tricks such as plugging the USB in first and then connecting the plug to the wall but none of these have worked.
