Well, now that I'm a couple hours too late...
1) NEVER NOT DRY ANYTHING WITH SUGAR IN IT IN PLACE! It turns to glue.
2) NEVER HEAT ANYTHING THAT IS ACIDIC! Heat accelerates corrosion.
3) Do not clean with water!
What Perris said. Pull HD and back it up if there is anything important.
The juice has to come out immediately. It is acidic and will cause leakage paths in the circuitry. Sugar will gum up the keyboard and fans, cause dust and dirt to stick to circuits and heatsinks causing electrical leakage and reduced heat transfer.
-Shutdown and turn the laptop over to shake out as much OJ as you can.
-Use a dry cotton cloth to wipe excess OJ from all surfaces inside and outside. Yes, disassembly is a must.
-Dampen another cotton cloth with isopropyl alcohol to wipe off all surfaces especially around the keyboard, fan, etc. Preferably you should flow isopropyl over all surfaces that are not sealed.
-Let the unit air dry at room temperature.
When you get the laptop working sell it quick because without compressed air and a hefty supply of isopropyl you will never get it clean.
Good luck.
PS Your day is going better than mine. I'm home 4 hours late because I fried a $100k unit at work today...
