Got my SP3 i7 256 last Monday. Forum has answered several of my questions already. Saw a yellow triangle next to my Microsoft keyboard cover in device manager. Troubleshoot said to update drivers. Got message that no divers installed, searched for drivers and message said no drivers available. Are there supposed to be drivers for this keyboard case from Microsoft? Cost me about $100. Keyboard does work except it won't enter my password on Start screen. I do turn off my SP3 every time I shut down. Once I get it set up will use it only for travel until my desktop dies then it will be my main pc.
