I don't understand your use of the words "unloading" and "leave a few hours
without calling".
It seems like you are saying that if you completely drain the battery that the
type cover works until you restart and the battery is charging.
I know you have been posting about this in several threads and have started
several threads, but this definitely sounds like a hardware problem.
If this is the case, the ONLY thing you can do is contact support for an out of
warranty exchange and if you are not in a country where the SP3 is/was
officially sold, you will need to find someone in a supported country to handle
all of this for you.
Sorry, but this is the bottom line.
>> My type cover does not work, but it only connects when I leave the Surface completely unloading. Besides letting it unload, I leave a few hours without calling. After all this, I'm going to turn on the type cover works.

>>ie the type only connects when the battery is unloaded. But if the battery charge and I reboot or disconnect the surface no longer cares.
