Microsoft Surface 3 plugged in but not charging, and it's out of battery

[simonhsieh]

I have a Microsoft surface 3, but it's not charging even though the power connector is plugged in and it is lighting up. Now it is out of battery, and everytime I try turning on the surface with it plugged in, it keeps showing up the low battery icon. Also, I left the surface plugged in for about 7 hours during my sleep, but it still shows the low battery icon when I turn it on. I tried searching up how to fix the problem but none of the methods work. So how do I fix this? Thanks
