    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! :(

    May be worth trying the troubleshooting steps below:

    1) Shut down the system with reopen windows when logging back in disabled

    2) Now that the laptop is off, plug in the power cable. Along the left-hand side of your keyboard, press and hold CTRL + ALT/Option + Shift at the same time as the power button for 3 seconds. Then let go of the keys.

    3) Press the power button to turn your Mac back on, then immediately press and hold CMD + ALT/Option + P + R until you hear the Apple boot chime 3 times. Then let go of those keys.

    Please quote this to let me know if it's any better.

    Do you notice and bulging of the trackpad or the underside of the computer? A trackpad that's acting out and performing actions on its own can sometimes be caused by a defective and expanding battery pressing up against it.
