Keyboard keys not working? You can usually replace the entire keyboard yourself for saving the money .The Operation isn’t as hard as you think ,removing your laptop’s keyboard usually involves simply unsnapping a cover,removing a few screws,and disconnecting a cable.Here we show you how this works.
Fix a broken key
A broken keyboard key can have many causes.
In the best case,just a lot of dust collected under the button,which can be easily removed.If liquid causes the problems , can also be fixed with a little luck.
Remove: Place your finger nail, small flat-head screwdriver, or knife under a corner of the key and gently pry the keycap up and away from the laptop.
In many situations, the key only snaps out partially. If the keycap is still attached to the laptop use your fingers to remove the keycap completely.
Once removed you should see the key retainer (scissor-switch) still attached to the laptop with the pad in the middle. If needed, this too can be removed from the laptop by placing the flat head of a screwdriver or a knife’s edge under a corner and gently twisting until it pops off.
Cleaning: If the button is removed, you can clean its underside with a household or microfiber cloth. Where the button rests, you will find a small rubber button in the middle. This should be cleaned very carefully.
Installation: Then replace the button in its place, then press down on the button from the top downwards until it clicks into place. If the problem is not solved yet, follow the instructions in the next paragraph.
