How to Clean the Laptop Keyboard

Friday, June 15th, 2012

It’s a good idea to clean your laptop keyboard regularly. However, to avoid damaging it, there are some things you need to keep in mind when you are removing dust and particles, or cleaning the keys.

Every so often, you can use a vacuum to clean your laptop keyboard. Use the little portable vacuums, with either the tiny (toothbrush-size) brush or the upholstery-cleaning attachment. This effectively sucks up all the crud in the keyboard. It’s amazing to watch.

Some people prefer to clean the keyboard by using a can of compressed air. This is not recommended, because the air can blow the crud in your keyboard further inside the laptop. Instead, use a vacuum.

Remember to have the computer turned off when you do this!

To clean the tops of the keys, use isopropyl alcohol. Soak it up into a soft, dust-free cloth, or use a cotton swab and gently rub the key tops. Try not to drip any alcohol inside the keyboard, and never use a spray cleaner directly on the keyboard.

In addition to cleaning your keyboard regularly, you should also consider washing your hands from time to time.

Laptop Keyboard Not Working

Friday, June 15th, 2012
Having trouble typing on your laptop keyboard? Read this article which will help you in troubleshooting your laptop’s keyboard problems.

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.

Problem #1 – My Laptop’s Keyboard Keys are Not Working

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

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. Similar to the manner in which you lubricated the keys, apply mild lubricant on the keyboard surface and let it dry.
  7. 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.

Problem#2 – My Laptop’s Keyboard Types Wrong Characters

When your keyboard types wrong characters, it is because of a software problem and not a hardware one. If you accidentally press specific keys on your keyboard, it can activate a particular function responsible for the problem.

Troubleshooting Steps

  1. Select the control panel option
  2. Click on → ‘Regional and Language Services’ → ‘Languages’ → ‘Details’ → ‘Key Settings’
  3. Choose the option ‘Switch Between Input Languages’ and click on ‘Change Key Sequence’
  4. Make sure that all the check boxes in the window are unchecked and repeat the same for ‘Switch to….. (Keyboard Type)’
  5. Click →’Ok’ → ‘Ok’ → ‘Apply’ → ‘Ok’.
Problem#3 – My Laptop’s Keyboard Types Numbers Instead of Letters

This is another problem due to some software issue. It is possible you may have enabled a digital lock unknowingly.

Troubleshooting Steps

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.

Computer Keyboard Cleaning

Friday, June 15th, 2012

Benefits:Cleaning your computer keyboard will not only result in sticky-free keys but also ensure that your keyboard will continue to function properly by removing dirt, dust and other particles that can damage the keyboard’s circuits.

Cleaning the Keyboard
1. Unplug the keyboard and turn it upside down and shake to remove and dust/dirt/crumbs that may be stuck in the keyboard. (It is advised that you do this outside or over a garbage can.)

2. Take a can of compressed air and spray in between and around keys while holding the keyboard upside down to remove any remaining unwanted particles. (You can use the soft brush attachment of your vacuum cleaner and vacuum out the junk instead of using a can of compressed air.)

3. Wrap a cotton cloth or paper towel around your pointer finger and moisten it with a mild cleaning agent or rubbing alcohol and use it to clean the top of the keys. (Be careful to not add too much liquid or else it may drip into the spaces between the keys and damage the circuits.)

4. Take a cotton swab and moisten it with a mild cleaning agent or rubbing alcohol. Use this to clean in between the spaces of the keys.

5. Let your keyboard dry and plug it back into the computer.

Spills: If you spill a liquid onto your keyboard (or laptop), disconnect the keyboard (or remove the batteries in a wireless keyboard), turn it upside down and shake it gently to get as much liquid out of the keyboard as you can. With the keyboard turned upside down use a paper towel or cloth moistened with water and try to wipe off the top of the keyboard. Let the keyboard sit upside down overnight to dry off. (Blowing the keyboard with a blow-dryer can quicken the drying process)

Note: Purchasing a keyboard cover or protector will protect your keyboard from dust and any unexpected spills that may occur.

Laptop Cleaning

Friday, June 15th, 2012

Benefits:Laptop cleaning is a quick fix for sticky keys and blurred screens. In just a few minutes, cleaning also can improve the overall performance of your notebook.

Cleaning Tools
Tools for cleaning a laptop are easy to find and inexpensive. A lint free cloth and an old toothbrush will generally do the job. However, for some areas of cleaning, in place of the toothbrush you may want to use compressed air or invest in a computer vacuum.

1. Turn off your laptop. Give it a minute or so to totally power down and then unplug it.

2. Clean your screen. LCD screens are fragile. Do check your manufacturer抯 recommendation for the best way to clean yours. However, in most cases, all you need do is wipe it with a damp cloth, making sure to wring out all excess moisture. Most importantly, unless you manufacturer recommends differently, don抰 use alcohol or ammonia based cleaners.

3. Wipe down the keyboard. Remove crumbs and debris using your toothbrush (or compressed air or vacuum). Wipe again.

4. Remove dust and debris from vents with the toothbrush. The propellant in compressed air may contain moisture. Some manufacturers suggest that computer vacuums may damage electronic components. Remember always to check your manufacturer抯 recommendations.

Tip: Always use a lint free cloth to clean your computer. Instead of picking up debris, paper toweling can scratch your screen and leave paper lint on your machine.
Tip: Never spray any cleaner directly onto your computer. Always wet the cloth with the cleaner whether using water, a homemade solution, or a commercial preparation.
