Fans not kicking on, and other issues
Tea was spilled and the fans sucked it into the machine. Right before it died, the fans were running full bore. When trying to restart, it would show the start up screen (Apple with spinning loop) but after a few second of trying it would go black.
I could start it off the start up disc.
I ran the hardware test which came back clean.
I disassembled the guts of the machine looking for crud. Found a little on a connection. Re-assembled the machine.
It started and worked (I was surprised).
However when shut down again, it would not restart, went back to original behavior.
I zeroed the HD and reinstalled the OS.
It worked. Everything seemed fine.
Used it last night for the first time. We were watching movies off of it which makes it heat up (heavy on the graphics card).
Once it was hot it 'black screened' for a few seconds, by 'waking it' it would come back, then 'black screen' then come back....could have done this all night.
When it wold come back I could tell the fans were not running (it was very hot).
I removed the battery, plugged it in, held down the power button until it started.
Now it will stay awake for ~3 seconds then go to sleep. I can wake it up but it only lasts ~3 and goes to sleep again.
I don't know if the fans wok because it will not stay awake long enough to heat up.
Es esta una buena pregunta?
+1 for a well written question in the sense that you explained what happened, what you did to try to fix it, and what the current symptoms are!

Had a chance to run a few more test.
Started the machine without the back on, the fans do work. They are just super quiet.
The trackpad is not interacting with the desktop but it does with the main menu. During the 1-2 seconds that the machine is awake, I can not click on anything on the desktop. Nothing responds.
However I can click on any of the main menu items for the OS and those work fine.
This testing is is hard because it only wakes up for 1-2 seconds at a time with 2-5 sleep cycles.
Using the Application CD that came with it I ran the Hardware test that come on it (held down the "D" key during start up. The quick test finds no issues. I can not run the long test because there is no touch pad response, so I can not select the larger testing option.
Also, I can not book off of the start up disc. It completely ignores it and goes straight to the regular start up cycle...of course it takes few naps along the way.
These sleep cycles only kick in after the system seems to find the start up disc. While it may spin for 10 seconds to find the start up disc, once it is found it does not stay awake for more than 2 seconds.

I found the Ambient Light sensor cable and disconnected it. Restarted the machine. No change in performance.
When started, and viewed through projector, I went to System Preferences > Displays. It is not detecting multiple displays. There is no ability to arrange the 'two' displays. Clicking on Detect Displays does not do anything. It still only detects one display.
Is is possible that it never detects the display? ...even though the start up Apple/spinning wheel show up?
It thinks the top is closed all the time?
When a machine that is not broken is started with the top closed, does the display still show the start up Apple and spinning wheel?
Is there some switch that tells the machine the top is closed that can be looked at/fixed?
