Trackpad touch and left button doesnt work after small water spill.

I had this same problem; I actually touched the touchpad with slightly wet hands and it stopped working. I spread the slightest bit of baby oil/oily cream, weird as it sounds, just on the touchpad and then wiped with a towel, and this has completely worked for me. Hoping I could be of help to anyone.

It took from Thursday afternoon till Saturday afternoon, but it’s working. And it really wasn’t that much — it was HOT coffee and probably a tablespoon, but every drop on the touch pad. I did turn it off and on during the 48 hours. Checking. Had kinda given up. I set it up like a camping tent and a couple of times a day used my blow dryer on low — and swirled it around inside and on the backside where the vents are. At night, it was next to my ceramic space heater. I also gave it belly rubs a couple of times a day, and now — all seems to be well. Something kept trying to update when I’d turn it on a couple of times, but it would hang up, so this last time as it began to “update” or spin or whatever, I just decided to walk away and leave it alone and when I came back in 10 long minutes, it was working. it is still in warranty, but I just didn’t want to deal with the COVID drama of whatever I’d need to do. So, don’t despair — belly rubs.
