water (& in my case wine) and keyboards do not mix. Laptop keyboards are two rubber membranes with a graphite type of mix a thte points where keys are. If these are damagd in any way it is a new keyboard (or worse it could have damaged the keybard driver chips)
Can you try another keyboard? (either extrnal not wireless or ' swap' from another portable.
