Hi Richard,
I'm Dyari. Thanks for reaching out. I am sorry to hear that.
It would be best if you leave the computer off for 24 hours to dry completely. However, please turn it off again. If you can remove the keyboard, remove it and clean it with cotton smoothly.
It is important not to expose it to excessive heat, such as that from a hairdryer or sunlight, as this can cause damage.
Contact the manufacturer's support services to provide you with instructions to remove the battery and RAM. Please mention the exact model of your laptop to find the manual for you.
