Hello all desperate type cover owners ! There's still a hope !
I succeed today to get my keyboard alive and 100% running after a lot of time of loose and a lot of things tried :
- Cleaning
- Uninstall of drivers
- Different installation of Firmwares
- Recovery of windows with keep of files
- Recovery of windows without keeping the files
- Recoveries with redownloading windows from the web
- Hard reset
- ...
- ...
Keyboard was not working during months in Windows (just backlight, fn button led, and volume buttons)
It was however working in the bios, for what can be used in it : arrows, enter, mouse that had to be activated with two fingers)
Finally, a kind of combination of all the attempts has allowed me finally to recover the keyboard in Windows.
I pursued the idea to recreate the situation a type cover has never been attached to the Surface.
01 - With Windows running, remove (disconnect from the physical port) the Type Cover from the Surface
02 - Open "Device manager", go in menu "View" on top and choose "Devices by container"
03 - In the same menu "View", enable "Show hidden devices"
04 - This should make appear a "Surface Type Cover" section in the list, even if the keyboard is not attached to the Surface
05 - For each driver you see under this section and for which you can do it, right clic + uninstall / check the box to delete drivers and validate. Do it for all of them, even wacom, until the "Surface Type Cover" section disappears by itself from the container list.
06 - Then force the Surface to power off and go towards "hard" reset by maintaining the power button during more than 30 seconds (to be sure)
07 - The surface should be off, so run the tablet in UEFI bios by pressing and maintaining Power and (+) buttons
08 - Go in Device menu and disable the last option "Type Cover Port"
09 - Go in Exit menu and touch Restart button
10 - Let Windows start completely and when it's done, again, force power off and go towards "hard" reset by maintaining power button during more than 30 seconds
11 - From its off state, run again the tablet in UEFI bios by starting the tablet with Power + (+) button
12 - Re-activate "Type cover port" in menu Device
13 - Go to "Exit" / "Restart"
14 - Let Windows start properly and attached your Type Cover to the Surface Pro
After I did the last step, Windows recognized it as a new device, took some time to set it up and tell me that is was installed.
The keyboard was fully functional and I was happy.
I hope you'll be too !
Thank you, and your proceddure worked for me.
