Answers :

There may be dead integrated circuits on the main board since they often operate with extremely low currents and may not tolerate being subjected to voltages that could be applied via even very clean water; the stuff is conductive.\015\012
\015\012With the cost of labor as high as it is, especially on laptops, you might want to try this yourself, proceeding slowly and not chewing up the very small screws used to assemble the case.\015\012
\015\012You will need a very small Phillips screwdriver and while one can buy an entire set for 1-2 US dollars, these will often damage screws since they are not ground very well.\015\012For under $10 US, you should be able to buy a 'jeweler's screwdriver' set at Sears or Radio Shack that will suffice.\015\012
\015\012Examine the case carefully with the battery removed in case screws are concealed by it or the door holding it.\015\012Check the back panel and around any in- or out-put connectors for additional small screws not directly associated with the connector near them.\015\012
\015\012If you think you have them all removed, use a thin bladed 'putty knife' or similar thin but strong edge to carefully pry in the slot between the upper and lower case.\015\012Watch closely to see if a longer or shorter stretch moves when pried. If only a short stretch moves, look for more screws.\015\012The two halves will normally snap together before screwed in place so some force may be required to get the first stretch of case separated. Once you have overcome the first stretch, the rest will be fairly easy. \015\012Don't bother the upper display section, the problem will not be likely there but in the lower part of the case.\015\012
\015\012If you can remove this section, the keyboard will probably be held in place with another few screws and be attached to the main board via a very flat 'ribbon' cable.\015\012If you can remove it, check for residual water droplets under it and use cotton swabs to remove as much as you can without disturbing anything. \015\012If you can't see clearly how to remove the entire keyboard, slip something under it (after the screws are removed) to keep it clear of the main board. Use anything soft and not electrically conductive such as a piece of corrugated cardboard.\015\012
\015\012Move the whole unit to any place where some mild warmth is found and allow it to sit for several days before reassembling.\015\012
\015\012Check for a heatsink (aluminum structure) and any fans; use a clean small paint brush to remove any visible dust deposits.\015\012Don't clean the board except by using your breath since a paint brush can develop a static charge that can be deadly to the low-level circuits. \015\012If the water was pretty clean and no circuits were damaged initially, the system may be usable again.\015\012 \015\012     
Let it dry or take a blow dryer and dry it ,but first unplug it tilt it up on its side and make sure all water or licquid has run out hair dryer sould dry it out let set 1 day than restart '' that is if there was no electrical burn or smell or short out if this has happened it most likly will not start , try it

I have an ACER notebook Aspire 4920 and, I think, because an update I installed (prompted I may add by my laptop!) it is now not working. When I turn it on it goes into Startup Repair mode and then tells me it can't fix the problem automatically. It then gives me the options to either: System Restore (not actually an option as when I go on it it tells me I can't do this!), Windows Complete PC restore (which i can't do as have no Backup), Windows Memory restore, or command prompt.
