Hi

Thank you for your query

Unfortunatley it is one of these issues where you will have to wait, I would try to place the laptop near a warm heat source (please note this is done at your own risk in the sense that it is NOT to be put near a gas fire or any other appliance where it can catch fire), to dry up and then you can retry

If alot of drink was spilt then it will probably have seeped pass the keyboard down into the internals

If it is only a few weeks old did you purchase some sort of accidental cover? as you may be able to get it exchanged, to be honest it may be worth trying to exchange it anyway as it is only a few weeks old the manager of the store may allow it

I hope this has been useful
