Did you remove the keyboard PRIOR to cleaning?
Would suggest you use an external keyboard, plug into your USB port and type away.
This would help identify if its just the keyboard.

Keyboard & sencerboad not\woring


If you mean the laptop keyboard and Touchpad are not working ?
the problem might be caused by the same issue for both.

Laptop keyboard and keypad not working

Laptop keyboards are a little more delicate than keyboards used in desktop computers. Hence they face more problems.

Normally, they are replaced when they render defective. However, most of these keyboard issues can be taken care of or even prevented by regular cleaning.

Common issues like, keys not working on your keyboard, having to press keys firmly to get the output or any keyboard typing issues, can easily be handled at home.


Sometimes you may find certain keys of your laptop's keyboard to not be working properly. You type those keys but there is no output on the screen or you need to press these keys firmly to get a result.

You face this problem if you accidentally spill any liquid substance on your keyboard, or due to dust accumulating on the inside of the keys, pressing certain keys really hard while playing games or even due to absence of lubrication.

Therefore you are supposed to maintain your laptop's keyboard by cleaning and lubricating it regularly.

Troubleshooting Steps


Locate the "Fn" key in the lower right or left corner of the laptop keyboard.

The "Fn" key typically has different colored text on it or the key itself is a different color.


Locate the function (F1 through F12) key at the top of the keyboard that disables or enables the touchpad on the laptop.


To start with, take out each key. Use a small screwdriver to carefully pry each key by making it loose.

As they become loose, keys will simply pop off.


Also, take out the rubber piece present under every key. Keep the keys and rubber pieces in different containers.


Once you have removed all keys from the keyboard, you will have to clean the keyboard from the inside. Use cotton swabs or ear bubs and slightly dip them in water.


Avoid getting them too moist, as excess water can damage the keyboard. Meticulously clean the whole keyboard using moist cotton swabs, laying extra emphasis on key spaces.

Now, start cleaning keys you had earlier removed and kept in the container. Use foam rubber and lighter fluid to clean each key alone.


This will help in removing any sticky substance present on keys. Apply any household cleaner on these keys and let them stay for about 15 minutes. After this, wash all the keys properly using hot water and let the keys dry completely.

The small rubber pieces which you took out earlier and kept in the container have to be thoroughly rinsed in warm water, after you have sprayed a household cleaner on them. Soak these rubber pieces up in paper napkins so that they dry quickly.

To lubricate the keys, place all keys (facing top-down) on a flat surface. Apply mild lubricant from all sides, on all keys and leave them to dry. Avoid applying too much lubricant instead go for a light coat.

Similar to the manner in which you lubricated the keys, apply mild lubricant on the keyboard surface and let it dry.

Once you have cleaned and lubricated all the parts, carefully reassemble the keyboard. Begin with placing all rubber components on the keyboard.


Next, fix all keys in their respective positions cautiously securing the wire in these keys. Use your finger and press down all keys, one at a time, firmly so that they fit properly in the slots. That is it.


The complete process will take you a maximum of 2 hours. Cleaning and lubricating the keyboard in the above prescribed manner once a year, can prevent many such situations.


Pressing the 'Function' key along with the 'Num lock' key (Fn + Numlock) or press the 'Function' Key along with the 'Shift' and 'Num Lock' key (Fn +Shift + NumLock). This will disable the lock and consequently solve your problem.

This was all about solving your laptop keyboard problems that you can try out yourself. After trying all the above given options, if you still find the keyboard still not working, you will have to take your laptop to a service center to get it repaired


Touchpad Not Working in Laptop


Most modern laptops come with a touchpad mouse built into the computer.

If you've tried to use the touchpad and the mouse pointer on screen is unresponsive, chances are that you or someone else has accidentally disabled the touchpad using one of the Function keys on the computer.


To fix an unresponsive touchpad on your laptop, reactivate it using the Function key on the keyboard.


This process is different for each computer manufacturer.

Locate the "Fn" key in the lower right or left corner of the laptop keyboard.

The "Fn" key typically has different colored text on it or the key itself is a different color.


Locate the function (F1 through F12) key at the top of the keyboard that disables or enables the touchpad on the laptop.


The key typically has an icon that resembles a touchpad with a finger touching it or a touchpad with a diagonal line through it.


Press both the "Fn" and touchpad Function key simultaneously to reactive the touchpad on your laptop.


Move your finger along the touchpad to verify that it works.

Press the combination at any time to disable the touchpad again.


Hope this helps

How to Clean the Laptop Keyboard


The following will completely solve keyboard problems and return the keyboard to perfect operation.
This will require about 2 hours time once you have collected the proper cleaning materials.
Cleaning materials:
  • Cotton swabs
  • Cosmetic foam rubber cleaning pads ( use only with naptha (lighter fluid), NOT alcohol)
  • Paper towels
  • Rubbing alcohol
  • Water
  • Lighter fluid (naptha)
  • Fine tipped tweezers
  • Scissors
  • Kitchen strainer
  • Household cleaner, Windex or equivalent
  • Super Lube Dry Film spray (critical - DO NOT SUBSTUTUTE !) K-Mart automotive.
  • This is a PTFE (teflon) based lubricant which dries perfectly DRY and is ideally suited for this application.
Proceed as follows:
DISASSEMBLE:IMPORTANT: Make a keyboard map so you know where each key goes.Carefully pry each key loose with a small screwdriver and place in a container. They pop off. DO NOT use excessive force. There may be a small rubber piece for each key. Remove all of these and place in a separate container. CAREFUL, these are small and like to jump away.CLEAN KEYBOARD ( do this well...... you will be wonderfully rewarded ) Clean the keyboard with cotton swabs SLIGHTLY DAMPENED with water. Replace these often and BE SURE they are only slightly damp. If they are too wet the excess water will contaminate the keyboard through capillary action. This will clean all water soluble contaminants like Coca-Cola, coffee, and sugar residue. For the very small places, cut the foam rubber into small pieces and use the tweezers, again SLIGHTLY DAMPENED, for cleaning. You must clean each and every key space, inside and out, this is critical since this is where the key touches and moves. Repeat this procedure again using rubbing alcohol and cotton swabs but NOT the foam rubber as it disintegrates when used with alcohol. Finally repeat this procedure using naptha (lighter fluid) and foam rubber. You can clean even the smallest key guides with small pieces of foam rubber and tweezers. This action will remove any petroleum based contaminants as well as the grease that is sometimes used on the wider keys which may have guide wires, for example, the SPACE BAR.
CLEAN KEYS:Some keys may have wires attached and some grease on them, clean these first with cotton swabs and naptha (lighter fluid). Remove all traces of the grease. Place all keys in a kitchen strainer. Spray with household cleaner and let stand for 5 minutes. Rinse thoroughly with hot water and place keys on paper towels to dry. Let dry completely.
CLEAN RUBBER COMPONENTS:Place all rubber components in a kitchen strainer. Spray with household cleaner and let stand for 5 minutes. Use stopper in the sink so that you don't lose these if they jump out of the strainer. Rinse these thoroughly with hot water and place on paper towels. Fold the towels over and press to squeeze most of the water out of the pieces. Let dry completely.
LUBRICATE KEYS:Place all keys bottom-up on a paper bag. Lightly coat the keys, at a 45 degree angle with Super Lube Dry Film lubricant. Do this from all 4 sides to assure penetration and coverage into the small and critical guide spaces inside each key. Let dry ( this happens nearly instantly). DO NOT overdue this step as the carrier solvent may affect the plastic.
LUBRICATE KEYBOARD: Mask off the laptop with paper and scotch tape. Apply lubricant (as above in LUBRICATE KEYS) to the keyboard and let dry. All right, you now have perfectly cleaned and lubricated keys, keyboard, and rubber components.
REASSEMBLE:Place all rubber components into the keyboard. Install keys with wires. Make sure wire is secured in the key, usually snapped into place. Place ends of wire in the guide slots adjacent to the key location as you align the key. Firmly press down to snap the key into place. Install the rest of the keys by aligning and firmly pressing down.

Hp Compaq 6735s I clean it with multi purposes foam cleanser & the key board stop working since yesterday & I tried cleaning lt with a spirit


use of spirits in a keyboard is not recommended, it will eatup and destroy the rubber compounds that make the keys work. It can also damage the electronics inside. Find some canned air, try to dry it out as best you can with the air between the keys. Then try not to use it until it comes back to life. Until then try a usb keyboard in its place. Worst case scenario you will need to replace the keypad of the notebook. Its pretty easy fix though. Best thing to clean keyboards is canned air and windex on a paper towel for the key surfaces only. hope that helps. cheers

Letters sometimes won't work


I assume you have a desktop system with a plug in keyboard; if you have a laptop please tell me and I will type up instructions on how to clean the keyboard on laptops.
You might want to try cleaning out the keyboard.
Unplug the keyboard and hold it upside down; shake it gently and allow debris to fall (pressing the keys can help).
I would also either use compressed air or a small computer vacuum on the keyboard.
Let’s see if this working…if not we might need a through cleaning.
