If
All the Keyboard Keys Not Working 
If the entire keyboard keys
not working, we could feel clueless. However,
to get the answer, we need to understand the cause.
Some of the main causes which are involved in keyboard
malfunction are: the membrane or the circuit tray beneath
the keys is broken or smashed or if the small wire inside
the keyboard is worn-out or if the small connectors
beneath each keys are broken. If the main power cable
of the keyboard is damaged. There could be various reasons
but that should not lead to the replacement of the keyboard
if keyboard keys not working.
If we talk about the first reason that is the circuit
tray of the keyboard than we could see that keyboard
keys not working because the rubber material
under each key has been broken. The main cause behind
this broken rubber key pads could be improper typing.
If we keep on pressing any key with too much of pressure,
the key will either stop functioning or it will come
out of the keyboard. However, rubber keys pads can be
replaced. If the same happens with the circuit tray
of the keyboard we could probably realize that keyboard
keys not working.
Moreover, improper maintenance of computers is the biggest
issue. People are eating and drinking by keeping the
food on the keyboard. Any particles may get into the
computer and water spillage can happen anytime while
we are using the keyboard as a tray, especially laptops.
If that continues, one day we would see that keyboard
keys not working. So the best solution is,
to stop using the computer in this way or if we cannot
do so then atleast we should clean the entire computer,
especially the keyboard with the help of a vacuum cleaner.
