I have a surface pro 4 i7. The cover (UK English) is driving me crazy!! Every time I start up there are 3 or 4 keys not working - not always the same. Today it is f, I, ) and del.
I try all the usual tricks: power off/on, with/without the cover, clean the connection, try the 30 second press the power switch restart, bang it, kick it.
Eventually I get all the keys working again - until the next time. This is amazingly frustrating for such an expensive machine.
Any thoughts, suggestions are very welcome.
