Hi,
about two weeks my type cover stop working too. Nothing worked. I turned off hard my SP4. I launched UEFI, moved to devices, turned off type cover port, left UEFI. Then launched my SP4, turn him off hard again, launched UEFI, put type cover port on, left UEFI, run my SP4 and type cover wad responding. Till then, no problems yet, good luck
Thanks for that. Sadly, I tried that already and it didn't work for me.
I imagine that your issue had the same route cause, a misapplied firmware patch, but one that could be resolved by resetting that setting. I think that mine (and that of thousands of others that MS seems to be happy to ignore) has corruption somewhere else. Some believe their issue resolves in the power management portion, as their keyboards work when the device is full charged, but drops off when a certain amount of power has been used (again, this seems to vary between users).
So, as much as MS wants to claim, it doesn't appear to be a hardware issue, but the faulty install of firmware. If only we had a way to rollback or reapply the firmware. Does anybody know how this can be done?
