On my Inc2, sometimes it is hard to open the screen up with a push of the top button. Push it again and it might start up. Or maybe a few tries gets it to work. This makes it seem like I have a mechanical button issue. But sometimes it goes to the startup boot screen like it had shut off somehow. Maybe it was a long button push to restart or it was actually off for some strange reason. I don't know if it is a mechanical button issue, or a software issue. any ideas? Thanks.
