Hello (update...here I've fixed the other issues):

I've had a 2010 MCB (warranty expired last month):

1. Water on my trackpad:

Today I wiped my keyboard and trackpad with a moistured cloth/paper.
After restarting the computer, my trackpad (cursor) suddenly started acting up. I've seen this issue before on Lenovo when a friend spilled water over his keyboard.

I figured that somehow one or two drops must somehow gotten into the trackpad. I took out the battery, wiped everything around. There was no visible residue of water or a problem as far as I could tell.
Anyhow I used hair fan to dry the area and then put it for 3 hours (open without the battery) under hot flowing air from an aircon.

Screwed everything together after a few hours. First two minutes, everything was fine, then the trackpad started acting up again. Now sometimes it's fine(worked 2 hours without any issues, perfectly responsive), other times it doesn't work - like now when I got up and tried to use the computer again.

What else can be done? The amount of water was truly miniscule. Where I should look to clean it? What else to do?
I've tried to browse older threads and some people said this should take care of itself after a while..I don't understand how though. If there is some water residue somwhere on the contacts, how would it fix itself?

I am now using external mouse while with trackpad turned off.

2. Failed ATH hard ware test from CD

I tired to run the ATH test, stopped at 4.33min, got stuck. I could click on "stop test" button and move the cursor, but no response. Had to abort with shut down. Didn't attempt again.
btw. the trackpad acted up also in this "mode"..ie. excluding the possibility that it's a software issue.


Please help - i.e. tell me how to clean this thing.

Hot flowing air from an air conditioner was used to dry this out? Air conditioner exhaust carries moisture with the heat. That's how air conditioners work. They move moisture and heat from one side to the other.

If I'm reading this right, you just blasted a malfunctioning laptop with hot moist air.
 
Should've just kept it to dry for a day or two or put in a rice bag. Remove the trackpad and verify there is no moisture on any connectors.
 
One rain drop quickly wiped off was enough to cause my 2013 trackpad problems for weeks. It doesn't take much. Lots of stories around about ruined trackpads with just a small amount of moisture and its not considered a warranty item, you just misused or damaged it. Like dropping the laptop and breaking the screen, and then expecting warranty repair. You need accident coverage for that.

Anyway, keep it in a dry place. Some think laying the laptop upside down will help. if you are lucky, things will back to normal in two to three weeks. If not, time for a repair. Not sure how big a deal that is for a 2010.

You could try putting the laptop in a back with rice or desiccant, but it will still take awhile.
