together, it is not easy for the user to see when liquids
have fallen onto the circuitry below the keys.
Attempting to clean the keyboard with a spray on
cleaner or rag soaked with cleaner the liquid can drip
onto the circuitry sight unseen. Once the liquid seeps
between the layers of circuitry, it can cause corrosion or
other damage to the circuits. This can result in keys
which no longer operate, or which, when pressed, record
the wrong characters and other similar failures.
There is no repair for this problem other than replace-
ment. The solution is to become aware of the issue and
take appropriate steps to protect your keyboard.
Cleaning should be done with a rag dampened (but not
soaking) with cleaning solution. Use extreme care to
prevent liquid from dripping between the keys. Spraying
directly on the keys should be avoided. The spray should
be applied first to the cloth, and then the cloth wiped
over the keys.
