Can Macbook water damaged be fixed?

The bottom line is that Apple will not repair water-damaged Macs, regardless if you have an AppleCare+ plan or not. At best you may be able to get it serviced by a third-party shop that specializes with this type of damage.

At this point, I would suggest that you stop using your notebook as any further use could potentially cause more damage. Even if the water completely evaporates, it could still leave traces of conductive residue that can cause short-circuits. Do NOT be tempted to use rice or any other type of desiccant as these do not work and just add additional residue that would need to be removed.

FYI, Apple does repair liquid damaged laptops as long as it is not catastrophic damage, but of course it is not free. AppleCare+ also covers liquid damage at a reduced cost as long as a damage incident is still available. Of course no type of damage is covered for free by the warranty.

Turn the MacBook off and keep it unplugged. Open the top and put it somewhere on its side to let it dry out. If the water didn't fry anything you may be able to turn it back on and it will work. I spilled a half bottle of water into my MacBook Pro a few years back and did this and it turned back on. If the water fried anything and you have AppleCare you can probably send it in for repair. If you don't have Apple Care you can take it to an Apple repair site and they may be able to replace the bad components.

For liquid spills on the top of the laptop/keyboard area it is actually better not to tilt the laptop as it will cause the liquid to run to other areas and seep through cracks that it might not have done if the laptop was just left to sit still. There is a mylar cover beneath the keyboards which can keep the liquid from penetrating to the Logic Board. The edges of this mylar are not always sealed so tilting liquid to the side will cause it to escape the mylar cover. This is especially true for minor spills that may be contained within the keyboard area. I've seen a few liquid damaged laptops where people turned them upside down to drain, but ended up getting more liquid inside and around the Logic Board.

The exception would be if the liquid entered just one side or the by the back vents, then tilting the laptop in that direction would probably be beneficial.
