My latch works ok...push button, WAAAIT for it, then the click and it detaches with but a tug. My problems is that the task bar shows the Surface detach icon with a red X and the accompanying: Surface Detach: hardware failure. hum. yet it works. I do not plan to tug on the KB or tablet anytime soon while it is supposedly attached. I never do get the green screen popup saying its ok to detach...just the click.
