I plugged my ASUS Taichi Laptop into an external monitor via the VGA Adapter that it comes with. It was working fine, but then I configured a power option so I could shut the lid without it going to sleep (so I could use just the external monitor with an external keyboard/mouse).
Problem is though, now, when the lid is closed and I move the mouse, the mouse is moving around on it's own, but when I open the laptop lid back up, the mouse is fine.
- I looked under the lid when it was closed and the display properly shuts off on the laptop.
- It's not the external mouse/keyboard because I completely unplugged them and it was still happening.
- Nobody is hacking me or anything, I totally went into airplane mode/pulled the wire.
- I have a touchscreen, but I put a piece of paper over it and it wasn't doing it.
I was thinking it might be the trackpad being touched somehow by the screen when the lid is closed? But I went into windows 8 control panel options and I couldn't find anywhere to disable it (it sees the USB mouse I think).
