Surface pro 3 typecover not working

[pavan]

Hi Everyone,

My surface pro 3 type cover isnt working the tablet works perfectly fine, i know its quite a common issue, but the common solutions dint work for me so had to start a new thread

here are few things i tried:

1. Forced reset (volume up and power button trick)

2. wiped connector pins with alchohol

3. updated Keyboard HID driver

4. Restored windows

5. troubld shoot keyboard via windows trouble shooting

None of this helped.

i went to stores and tried new type cover, that dint work either. need your advise on how to get my typecover workin back again

Thanks,
Pavan
