2011 macbook air with i5 processor sandy bridge.

I recently repaired it by swapping out the logic board and replacing the battery.

For the most part it works great. However, when waking up from a long nap, sometimes it will not recognize the touchpad. Sometimes plugging in a USB mouse helps, sometimes it does not.

What is going on?
