I bought the surface power cover keyboard and a surface pro 2. If I have the keyboard connected to use its battery, but want to use the on screen keyboard for actual input (touchscreen), I swipe from the right of the screen, click settings, keyboard, and choose touch keyboard. Then the keyboard annoyingly fills up half of my screen. I click the hide keyboard button in the lower right corner so I can see what I'm doing. Then, the entire system automatically reverts to the power cover keyboard as the input method. How can I stop this? This makes the on screen keyboard completely unusable when using the battery from the power cover keyboard. I can't use my computer this way at all.
