Same Issue here with a surface 4 pro.
I´m really disappointed with Microsoft response about this issue. Now We have to pay again around $500 US dollars to get a replacement on this device. The only reason of doing it is because of the investment on all the accessories which costed a fortune and that we cannot spend again $1200 on a new device (we need this type of portable devices).
Is more than obvious that this is a manufacturer problem with a severe risk for the end user. A recall should be made. A total disappointment, and a replacement for the same device should be made at no cost.
Waiting on for the HAZMAT packaging material, after being mentioned not to use the device (but Microsoft mentioned that there is no risk of fire), to return the device and for an outrageous $500 dollars bill for a refurbished old device.
All microsoft stores are closed to public due to COVID19
