Surface book 2 not charging

SB2 started doing this on me 6 months ago and I haven't been able to fix it. It will charge through the screen port by itself, but it won't charge through the dock port (either through the surface connector or USB-C)... it will show "plugged in, but not charging" in windows. I just tried swapping the battery in the base but that didn't change anything, and I can't find any replacement boards (the main one in the base, has the USB-C and surface connector with all the smaller boards, battery, kb/m cables plugged into it) to try and replace that.

Pretty much useless $1000 laptop!

Just wanted to add a note to the above which worked well.

FYI 15" SB2 512GB 16GB RAM

Somehow, my power supply became unplugged and when I first plugged it back in, it did not appear to respond to the charge and the back of the unit was really warm. I removed the power connector until the back was cool, reconnected the power and left the unit for about 20ish minutes.

Following the additional guidance of holding the power button for about 20 seconds then worked for me to get the unit booted and useable and the unit showed that the battery was at 28% with 1 hour and 21 minutes until full charge (interestingly, looks to be about a minute of charge for 1% of battery)

So, in summary - hopefully this helps someone else if their unit drains completely and will not boot (even with power connected)

1. When you plug the unit into the charger, if the back becomes very warm, remove the power connector and all other usb connections until the unit is cool to the touch.
2. Once the unit is completely cool, reconnect the power connector and ensure the light is a solid white but do not plug any other usb devices in yet. In other threads, moderators have recommended to wait 5 minutes - I would suggest a bit longer to ensure a decent charge for booting and to ensure the unit is not still getting hot.
3. If the unit stays cool and the power has been reconnected for an appropriate amount of time per my #2, press and hold the power button until the white MS logo appears and then release (about 20 seconds depending)

This is how it worked for me but your mileage may vary :)

My wasnt charging so I unpluged and pluged it back in. Nothing happened. I restarted my cumputer and nothing happend. Then I shut it off and waited and cane back and it randomly started to work. I dont know why. But if it doesnt work after that the hold the power button for like 20 seconds to reboot you cunputer and it soulf work.

Yes, try that. It did work for me some months back. I did it when I was in laptop mode (screen attached). Hope it works for you.

I didnt receive any error message.

i didnt make any changes in my computer.

i cant update my compueter because i need 40% battery, which i dont have.

i did try to shutdown my computer. 

the charger is new so i that is not the problem it was working yesterday perfectly, i also tried to detach my computer and charge only the screen wich didnt work.

what do i do?

Did you try to uninstall and reinstall the battery drivers in device manager?
