I spilled water on my laptop a few days ago and some buttons don't work. Is there anything else you can do?
Have the keyboard replaced completely.
Let it dry quickly and turn it off. Otherwise it's junk
Maybe yes, maybe no. If you switched off the device immediately and there are no other problems and the chance is very small that the water has penetrated further, then the keyboard can be exchanged for a few euro. If you only use the device itself as stationary, you can of course simply pin an external one. ^^
Depends on
