How To Fix Defective Keys On My Keyboard?

We always asked "How to repair my keyboard?" or "How to fix defective keys on my keyboard?". Before, I was able to fix desktop and laptop keyboards. How did I done that? Okay! I am going to give you a hint on how did I done that. 

But before we continue, please read the site policy.
If you have already read this policy, continue reading this post.

First disassembled it right? then look for the burned carbon resistor printed on the plastic board or circuit board if it is in an old keyboard model. Then look for a stranded wire about 3 to 5 times larger than your hair. You can also use the stranded wire from power supply. Tape it on the burned carbon printed lines on the plastic circuit board of your keyboard better if you use transparent tape. Check if all lines are connected or shunted using the stranded wire, then try it. 

You can use my technique but this fix is not permanent. This shunt will burned some of new lines on your keyboard or some keys will not worked after a month or less than a month. Other use a pencil to shunt the lines on the keyboard.

So, is this the solution? Well this fix is not the solution you are looking for. Nowadays, electronic ink pen is sold in the market. If you can purchase one of this hopefully it will solve your problem. I am not saying that you should buy that or I recommended it to you. I have not yet tested the electronic ink pen. But probably that pen could be the solution for your problem. Same technique you should apply, you have to shunt the carbon using the conductive ink but the lines are too small you may have to use a magnifying glass.

So, to the question, Can I Fix Defective Keys On My Keyboard? for me now is a "NO". 
But if you tried the electronic ink pen and successfully fix your keyboard I think it's a "YES"


Here are my sample of laptop and desktop keyboard with burned carbon lines on it.

Most Common Problems on Automatic Voltage Regulator

Image
Hi there, today my post is about automatic voltage regulator. What goes into your mind when you hear the term automatic voltage regulator? Yes, its automatically regulate voltage, right? So how this automatic voltage regulator affects our computer? Actually this device does not affect computers directly. This device does not speed up our computer but it protects our computer parts from easily burned during voltage fluctuation. Also it provides step down power for devices from Japan or the US. If we live in Asia and plug this devices, this action could be a disaster to this devices. In Japan and US voltages are in 110volts to 120volts only while in Asia most devices runs in 220volts. So, this AVR is not only for voltage fluctuation but also as step down power. So, what are the most common problems of automatic voltage regulator? I have here the list of problems that we might encounter if we have a defective automatic voltage regulator. 1. Defective Plug Defective plu

If we encountered defect on our old mouse we normally buy new mouse. Like when mouse often stuck, we always get angry and usually replace it with new one. What if you don't want to buy and still want to use your old mouse. Below are the steps to fix your defective mouse. But before we continue, please read the site policy .

Small screwdriver (Phillips) This procedure is only applies to stuck mouse or infrared sensor often turns off for both PS2 and USB Mouse. Step 1. Remove the mouse from your computer, remove the screws from the mouse. Step 2. Cut the wire that connects to the mouse side about 1/2" or 3/4" inch. Same size inside or about 1" inch. Step 3. Solder the wire to connect both end. To connect the wire if the color is red it should be connected to red end also, you should fo

Typical Computer Headset Wiring Diagram - Barkingmode.

Image
Hello guys, I have today a wiring diagram which I traced the wiring from a cheap headset. Drawn and transferred to a computer to create a .jpeg file. I also, color it so that it will be easier for everyone to analyse the connection. This will help us remember the connection easily if we break the wire unintentionally. Having a wiring diagram connection of plug and wiring will be easier for us. See the headset wiring diagram below. The speakers on the drawing is a symbol and not the real thing as a drawing. Volume and microphone is a real image as a drawing. Only the Left and Right speakers are the symbol on this wiring diagram. You can also identify the location of the left and right speakers in the speaker plug. The mic input in the plug also shows its pin configuration and wiring of the microphone. This will help us locate easily the pin of the speaker in the plug or the mic-in in the mic plug. Last modified: Aug. 31, 2019.
