So I was browsing the net and the trackpad suddenly becoming unresponsive. lots and lots of lag. dragging the mouse across the screen and it suddenly "brakes". page up and down with 2 fingers is the the same. I turned off the machine and I'm still getting the same results. from what I can see, the keyboard is dry. I definitely didn't spill any liquid while using it. It's not related to browser I believe since I was experiencing the problem even before I open chrome! Any ideas? thanks edit: after creating this post, the screen zoom in and out by itself before returning to proper size!
