Is your computer keyboard acting up? Don't worry, we can help you fix it! Repairing a keyboard is not only a useful skill, but it can also save you money and extend the life of your device.
Let's dive into the steps we need to take to get your keyboard back in top shape.
First, we should diagnose the issue by rebooting your computer or connecting a USB keyboard. Once we identify the problem, gather essential tools like a screwdriver and a multimeter.
Next, we'll carefully disassemble the keyboard, keeping track of screws and keycaps.
Now, let's check for any damaged parts, like ribbon cables or faulty components. If we find any issues, we can use jumper wires or conductive ink to make quick repairs.
After we've fixed everything, it's time to reassemble the keyboard, making sure everything fits perfectly.
Finally, we'll test each key to ensure they all work before tightening the screws.
With these steps, you'll not only fix your keyboard but also gain valuable skills for future repairs!
Diagnosing keyboard issues is a critical primary step in resolving functionality problems.
Begin by rebooting the computer, as this action can often remedy temporary glitches. If the keyboard remains unresponsive, access the UEFI/BIOS settings during boot-up; successful navigation here typically indicates a software issue rather than hardware failure.
To further investigate, connect a USB keyboard to ascertain whether the malfunction is hardware-related. Observing the keyboard's behavior—such as intermittent key functionality or consistent failures in specific areas—can provide insights into the underlying cause.
Furthermore, utilizing built-in diagnostic tools available on certain laptops can improve the troubleshooting process, allowing for a more efficient and targeted approach to identifying and rectifying keyboard malfunctions.
Regular maintenance and cleaning practices can also play a significant role in preventing keyboard issues from arising in the beginning place.
Tools and Supplies Needed
When preparing to repair a computer keyboard, having the right tools and supplies is vital for a successful outcome. Making sure you have the appropriate equipment will streamline the repair process and improve your diagnostic capabilities.
Dr IT Services - Computer Repair, Laptop Repair & Data Recovery
I contacted Vlad after my son fried my laptop by using his powerful charger in my less powerful laptop. I was very anxious.
He was very responsive when I made initial contact and I was above to drop my laptop off that morning.
The service was supremely… More professional and very quick. I even brought my son's laptop (which was broken and that is why he was using mine) to be fixed too.
I was given clear prices and expectations for how long the repairs would take. Both repairs were completed very quicker and exceeded expectations.
I would highly recommend Vlad.
Highly recommend.
I contacted Vlad as my laptop wasn’t working. (Would not power up). I dropped it off to him in the morning. Then later that day he was able to diagnose the fault and put forward a plan to resolve.
Unfortunately it was not economical… More to repair, but he was able to source the perfect replacement for my budget. Which I couldn't be more happy with. For a small fee he was able to transfer all my data over to the new device.
All turned around in a few days.
The service was fast, friendly and had great communication. I would highly recommend to anybody who needs their devices repairing.
Thanks Vlad.

5/5 .
Merry Christmas Vlad..cheers see you around!
I bought an expensive gaming laptop which was shutting down whilst gaming, and I suspected it might be because the operating temperatures were too high.
I reached out to Vlad one morning and he offered to take a look at the laptop and repair it the same… More day. He was very polite and knowledgeable about the laptop I'd bought and about the CPU and GPU therein, and was aware that they were prone to overheating. He knew immediately what to do to fix it, so I left my laptop with him and shortly thereafter Vlad let me know that he had finished and the laptop was ready to collect. He was so efficient I could barely believe it! He took pictures throughout the process of the internals (before and after his repair) and showed me them on arrival.
I took the laptop home and sure enough the operating temps are ~15c less and the laptop now works perfectly. Thank you Vlad! And all for a very reasonable price. Please do not hesitate if you are thinking about using Vlad! If I need anything IT related from now on, Vlad will be my first point of call!

I highly recommend that you talk to him if you have any issues with a PC before going to someone else.
Exceptional Service!!!I had some issues with my PC last week, with my SSD, and I thought I have lost my university assessments because my PC did not open anymore. Another issue was that I did not know anyone in my area that could fix my PC but I am glad… More that I have found and meet Vlad. He manage to fix my PC in one day just in time to be able to send my assessment to the university in time and the problem was solved.

A small Phillips screwdriver (or Allen/Torx drivers, depending on the keyboard model)
An Ohm Meter or Multimeter for electrical testing
On-Screen Keyboard software for functionality assessment
30-gauge insulated wire and a conductive pen for creating jumper wires and repairing connections
Additionally, it's beneficial to consult resources on common laptop issues and costs to better understand potential problems you may encounter.
Maintaining a clean workspace and using storage containers for screws and small parts will help prevent loss and guarantee organized reassembly.
Equip yourself with these necessities to achieve mastery in keyboard repairs.
Disassembling the Keyboard
Disassembling a keyboard is a crucial step in the repair process, and it requires careful attention to detail to avoid damaging sensitive components.
Begin by ensuring the keyboard is unplugged or turned off to prevent electrical damage. A systematic approach, as outlined in keyboard diagnostics, can help identify any potential issues before disassembly.
Utilize an appropriate screwdriver, typically a small Phillips or Allen, to remove the screws that secure the back cover. Gently separate the top and bottom halves while ensuring any ribbon cables connecting the keyboard assembly to the motherboard are carefully disconnected, as these can be fragile.
Next, remove the rubber covering the internal circuits and clean it cautiously, avoiding scratches on the circuit lines. Organize all screws and small components in a container, and document the layout of keycaps to facilitate reassembly.
Repairing the Keyboard Matrix
Repairing the keyboard matrix is a crucial process for restoring functionality to a malfunctioning keyboard. Key steps include accurately diagnosing issues and implementing targeted repairs, as keyboard problems can often be linked to underlying hardware issues such as performance lag or overheating.
Consider the following important techniques:
Create jumper wires to test the keyboard encoder, identifying faulty lines within the matrix.
Apply conductive ink to damaged areas, allowing for a drying time of 10 minutes while maintaining separation of matrix sheets.
Measure resistance post-repair; a reading of around 2 ohms indicates successful restoration of connectivity.
Carefully trace ribbon cables, which represent the X and Y axes, to locate problems without damaging the cables during disassembly.
Reassembly and Testing
To guarantee a successful reassembly of the keyboard, it is essential to meticulously place the flexible caps at each key position on a clean, solid surface, verifying their proper fit.
Begin by cleaning any debris from the caps and matrix sheets using a wet cotton swab. Next, align the matrix sheets with the corresponding holes for the raised plastic keys, ensuring that no sliding occurs to maintain cap alignment.
Carefully position the backplate over the matrix sheets, aligning it with the anchor holes, and insert self-tapping screws loosely for final adjustments.
Reattach the Keyboard Assembly to the Keyboard Encoder board and test each key for functionality. Once confirmed, tighten screws in an alternating pattern for even torque distribution, followed by a thorough final key test.
