Coke ran onto my keyboard, which has meanwhile dried up, now it no longer works, do you have an insider tip on what to do?
Just use an external USB keyboard. Or exchange the defective one for a new one.
Dismantle, soak in water for a few hours with a drop of washing-up liquid to dissolve the cola residues again, hurl or blow out as much of the water as possible, and then rinse several times with distilled water to remove residue.
Then let it dry thoroughly and completely on a warm heater for several days and hope that everything will work again afterwards.
Until then, connect an external USB keyboard to the book.
