i think its my keyboard causing the error cos i spilt juice on it couple of days ago (tho managed to fix it) but not 100% delete key wont work for example, everything else fine
Take it apart and clean it. You can soak the silicon membrane and keys in warm water and dish soap. The circuit board you'll have to be careful with and use something like 91% Isopropyl Alcohol. Be sure it is absolutely dry as a bone before you reassemble it.
