Spilled coffee on Mac air keyboard...what can I do after cleaned up?

There are so many factors to account for, that it is impossible to even guess how bad the damage is.

Most of the time, it is serious. Coffee, with a little cream and sugar, contains just about everything that is bad for a sensitive electronic device. The fluid conducts electricity, it is likely corrosive, and it makes physical switches/keys awfully sticky.

If it made its way to actual electrical contacts, the keyboard is the first likely component to undergo irreparable damage. If it gets into the main board too, then the notebook is vertible scrap metal and glass.

The keyboard alone may cost you at least half the value of the system, to replace.

The question is not one that can be answered here, since a careful physical examination and diagnosis of damage is required. Take it into your local Apple Store to begin with.

lol

if it's just your keyboard, than the replacement part will be approx 250 usd, if you trackpat is also damanged the part will be approx 90, both are not including labour.

if internals are also damaged the most economical fix is to buy a new mac unfortunately.

barbara, this may be a good time to do a backup.

To be a bit grim, for a moment.

Backups on a daily basis would be my plan now. Hope it works well, but be prepare for the worst.

Good luck.
