An often underestimated fault in laptops: a defective laptop display cable.
This week we’re showing you a specific example from our workshop – an Asus ROG Strix G15 G513QY where the display remained completely black. At first, everything looked like a classic display failure, but in the end, a defective display cable turned out to be the actual cause.

Fault description: Display remains black

The owner from Baden-Baden brought us the laptop with the description: “Display no longer works.”

Even during the intake process, it was noticed that the device was not optimally packaged – so possible transport damage could not be ruled out. The team documented everything with photos. Since a black display on many laptops indicates a defective panel, the initial suspicion was a display fault.

Initial misconception: new display installed

The technician therefore replaced the entire display as a test – a typical repair step for an apparently “dead” screen. But even with the new panel, the screen remained completely black. It was then clear: the problem must lie deeper – either the new display was also defective, or the laptop display cable had a glitch.

Clue to the real fault: cable movement affects the image

During further testing, it was noticed: when the technician moved the display cable slightly, the image suddenly flickered briefly – sometimes blurred, sometimes with dropouts, sometimes completely gone. This effect is typical for a defective laptop display cable. Constant movement when opening and closing the display can cause the cable to wear out or break over time. The old display was reinstalled as a test – and the behavior remained the same. Now it was clear: it wasn’t the panel, but the display cable causing the fault.

Solution: Replacing the defective laptop display cable

After the clear diagnosis, the technician ordered a new display cable for the Asus ROG Strix G15 G513QY and replaced it.

The result: The display immediately worked perfectly again – clear colors, full contrast, no dropouts. Since it was a private device (recognizable by some stickers on the case), we offered the cable replacement at a particularly fair price. A great example of how the targeted replacement of a defective laptop display cable pays off – instead of unnecessarily replacing an entire display.

What actually happens when the laptop display cable is defective?

A defective display cable shows itself through very typical symptoms:

  • Flickering or black display
  • Blurred image or color distortions
  • Display only works at certain opening angles
  • Image cuts out when you move the display

The reason: The display cable transmits data and power from the motherboard to the screen. Over time, it becomes brittle or loose due to movement and mechanical stress – especially with gaming laptops like the Asus ROG Strix G15 G513QY, whose display lid is moved frequently.

Here are answers to the most important questions

A defective display cable often shows symptoms such as a flickering or black display, blurred image, color distortions, or when the image briefly cuts out when moving the display. A display that only works at certain angles can also indicate a cable problem.

This is often due to a damaged or loose display cable. Mechanical stress from frequent opening and closing can wear out or damage the cable, leading to connection problems between the motherboard and the screen.

Not always. In many cases, a cable replacement is sufficient and more cost-effective than replacing the entire display. A professional diagnosis can quickly identify the exact fault.

Replacing a cable is usually significantly cheaper and faster to perform than replacing an entire display. This saves costs and minimizes the repair duration.

It is advisable to have the device checked by a professional. Often the cause is not in the panel itself, but in the display cable. A professional diagnosis ensures a targeted and cost-efficient repair.

If your screen flickers or stays completely black, the problem is often not with the panel, but with the display cable. A professional diagnosis saves time and money – because replacing a cable is significantly cheaper than a complete display. Our technicians check your device carefully and only repair what is really necessary.

Fault description & preparations

Fault description:
The customer reported that the MacBook Air M1 no longer charges despite being connected to power. The charge indicator sometimes stayed at 0%, and the device shut off immediately when no power was connected. This points to a defective battery that is no longer being detected by the charging controller.

Initial diagnosis:
After checking, it was confirmed: the power adapter and USB‑C ports were working perfectly. The battery showed no voltage anymore, and “Service Recommended” was displayed in the system, so a replacement was necessary.

Preparation:
For the replacement, you should have a precision tool set ready, as the M1 model uses very small screws. The IPC-Computer tool set for laptop repairs is ideal for this and is available in the IPC-Computer Shop.

Before you start:

  • Shut down the MacBook completely
  • Remove the power adapter
  • Prepare an anti-static workspace

1. Remove the bottom case:
First, loosen the ten Pentalobe screws on the underside. You can then carefully lift off the bottom cover using a plastic pry tool. Underneath is an additional cover over the mainboard—this is also removed to access the battery connector later.

2. Disconnect the battery connector and touchpad cable:
Before removing the battery, be sure to disconnect the battery connector from the logic board. The touchpad flex cable must also be unplugged, as it runs over the battery and could otherwise be damaged.

3. Remove the speakers:
The speakers are located to the left and right of the battery. They must be removed, as some of the battery screws are underneath them. The speakers are also secured with strips (adhesive strips), but can be removed easily by carefully pulling them out.
Good to know: With this model, mounts usually don’t break during this step—so removal is comparatively safe.

4. Remove the battery:
The battery is secured with several Tri‑Wing screws. After removing these screws, it can be lifted evenly out of the case.
On our device, there was also a light adhesive bond here, which could be released with gentle, even pulling.

5. Installing the new battery:
We generally recommend the original Apple battery, as it offers the best quality and an exact fit. The new battery is inserted, screwed in, and then the touchpad cable and the battery connector are reconnected. Next, the speakers and their wiring are reinstalled. (Strips are included free of charge with the original Apple battery)

6. Final steps:
Finally, the mainboard cover is reinstalled and the case is closed. After the first power-on, check whether the battery is correctly detected in the system report and charging starts.

Repair assessment from the workshop

  • Repair time: approx. 30 minutes
  • Difficulty: Medium
  • Special notes: Speakers and battery secured with adhesive pads; touchpad cable must be disconnected first
  • Recommendation: Use only original Apple batteries; precision tools required
M1 model

What should you watch out for when identifying the model?

MacBook underside

To make sure you use the right spare part or the right repair guide, the exact model number of your Apple device is crucial. This number always starts with an “A” followed by a “four-digit number”, for example A2337 for the MacBook Air M1 (13″, 2020).

You can usually find the model number on the underside of the device, in the system report, or in the settings. Because correct identification avoids compatibility issues and ensures a successful repair.

A customer from Schondorf brought us a Lenovo X1 ThinkPad Yoga 6th Gen (Type 20XY/20Y0) for repair. The notebook was no longer charging, even though the customer had already attempted repairs themselves. Upon closer inspection, irregularities such as missing battery screws, a bent heatsink, and improper soldering work on the motherboard were found. Such complex damage requires detailed diagnostics and professional replacement of the affected components.

The Diagnosis

Our technician, Gilbert G., found that work had already been done on the USB-C port on the motherboard. A protective component (CSD87501L) was completely missing and had been replaced by a bridge with adhesive. This component protects the rest of the electronics from overvoltage. Due to the missing protection, a soldered RAM chip (SN2001024YBGR) was damaged, rendering the motherboard irreparable. Troubleshooting was extensive and took approximately 6 hours, as all power paths and components were carefully checked.

After the motherboard replacement, the replacement date and time must, of course, be reset.
After the motherboard replacement, the replacement date and time must, of course, be reset.

Since the defective motherboard was no longer economically viable to repair, the entire board was replaced. The replacement was relatively straightforward:

Only the bottom case, fan, SSD, and some connecting cables had to be removed; the display unit could remain completely in the housing. The motherboard replacement itself took only 30 to 45 minutes (max. 0.75 hours). As part of the repair, the thermal paste was also renewed to ensure optimal heat dissipation.

The Result

After installing the new motherboard, the charging process worked perfectly again – the repair was successfully completed.

Technician's Conclusion

“The case from Schondorf once again shows how risky self-attempted soldering on modern motherboards can be. The removed overvoltage protection ultimately led to the total loss of the board here.”

– Gilbert G., IPC Technical Team –

If a notebook no longer charges, the fault is often not with the battery, but with the charging electronics or protective components on the motherboard. Amateur interventions can cause greater damage in such cases. Therefore, a professional should always perform the repair.

Today we’d like to highlight a typical but often underestimated issue that can occur with laptops: a loose connection at the power jack. We’re sharing a real-world case by taking a closer look at an Acer Aspire 5 (A517-52G) from our workshop.

A private customer from Aichtal brought in his device because there were two issues: the touchpad mouse buttons no longer worked, and the power jack was worn out but still functioning. These mechanical and electrical contact problems can quickly get worse if they aren’t identified and fixed in time. With a loose power jack connection, there’s a risk of a short circuit that, in the worst case, can permanently destroy the motherboard. In this post, we explain what matters and how we solve this problem efficiently.

1. Faulty touchpad

2. Loose connection at the power jack

  • Repair measure: replacement with an original Acer power jack (5.5 / 1.7 mm)
  • Procedure:
    – Desolder the old jack and solder in the new DC jack
    – Rework the connection points and reinforce them mechanically to ensure long-term stability

After both jobs, we carried out a final function and safety test (charging behavior, voltage spikes, power draw, touchpad response) – everything worked perfectly again.

Billing

For replacing the power jack, the jack replacement flat rate of €159 (including the original jack) was charged. In addition, one labor unit for the touchpad repair was added, bringing the total repair cost to €190 gross.

This made the notebook fully functional again – at a price well below the cost of a potential motherboard replacement.

Conclusion

A loose connection at the power jack is not a minor issue, but a potential hazard. Voltage fluctuations or short circuits can permanently damage the motherboard.
In this case, the customer from Aichtal did exactly the right thing by sending the device in for inspection.
Thanks to the professional repair – replacing the power jack with an original part and restoring the touchpad – the device was fully repaired in a cost-effective way.

For many, a gaming laptop is an important companion for gaming, streaming, or creative work. If it suddenly can no longer be reliably charged, this significantly limits enjoyment and productivity. In this post, we explain why a defective power supply or a damaged charging port causes such problems with the Gigabyte AORUS 17G YD.

Customer's fault description

“About a year ago, we had the charging port of the aforementioned laptop repaired by you. After that, the laptop worked perfectly again. However, since we unfortunately used no original power supply for the laptop, we suspect the port may now be damaged again.

The laptop won’t charge again. At first, we suspected the power supply was also defective and ordered another one. For a short time, about one or two days, the laptop charged again. But now it’s not charging at all, which is why we are unsure what exactly the problem is and whether it’s the port again or the power supply.

We made sure that every specification of the new power supply matched. However, it came from China, which is why we are now unsure and it’s possible that the port was damaged again because of it.

Therefore, we would like to have the laptop checked by you again and, if available, order a suitable power supply at the same time.”

Our technician's diagnosis

The Gigabyte AORUS 17G YD did not turn on with the supplied power supply. The function LED on the power supply remained off, and the laptop showed no reaction after being switched on.

AORUS 17G YD_2
AORUS 17G YD_3
AORUS 17G YD_4
AORUS 17G YD_5
AORUS 17G YD_7

In our workshop, the supplied power supply was first subjected to a standard measurement. A multimeter was used for this:

  • The black test lead was placed on the outside of the power supply plug,
  • the red test lead inside the plug.
    The result: No current flowed.

Thus, it was clear – the power supply was no longer providing voltage.

In the next step, the laptop was connected to a laboratory power supply.

Result:
The laptop started without problems – a clear indication that the problem was a defective power supply.

Why are original power supplies so important?

This example shows how quickly replicas from unknown sources – in this case, a power supply from China – can lead to serious problems. Even if voltage (V) and amperage (A) match on paper, the quality, stability, and safety of such power supplies often differ significantly from the originals. The technical internal components may also be of questionable quality.

Especially powerful devices like the Gigabyte AORUS 17G YD, which is originally equipped with a 230-watt power supply, should always be operated with the original power supply.

We recommended and sold the appropriate original Chicony power supply to our customer.

Our recommendation

The Gigabyte AORUS 17G YD model should only ever be operated with an original 230 W power supply. You can buy the power supply in our shop here.

Conclusion

A defective laptop power supply can be quickly bought on Amazon or eBay – it’s often underestimated that many cheap providers operate there, often supplying grey market goods or fake power supplies.

Those who rely on original or tested IPC-Computer spare parts prevent another quick power supply defect.

Logo_Tip_Notebook_Doctor

When experiencing charging problems, always measure the power supply and port first before assuming the worst. In this case, our technician was able to give the customer the all-clear after just a few minutes – the laptop was perfectly fine, only the power supply needed to be replaced.

The inspection of the charging port for a loose connection showed no findings. Therefore, a power jack repair was not necessary.

When your laptop breaks, the first impulse is often: “I’ll send it to the manufacturer.” Sounds logical at first – but practice shows that it is often more expensive than with independent repair shops. Manufacturers mainly work with centralized service centers where only components are replaced. Soldering is no longer done there, and therefore no real repairs are carried out. Especially in the case of mainboard damage, manufacturers charge up to €800 for a mainboard repair.

Fair costs or expensive complete mainboard replacement?

Chris_400x400

Last week I got an HP Elite-Book 845 G11 in our workshop for repair. Here, the defective display was to be replaced with an original HP display. I looked for the original display and its price, which was very expensive. A more economical solution had to be found! We found a similar display from another manufacturer and modified the connections a bit. It worked right away. But the best thing is that the customer saved a lot of money. Cost of original display: well over 300 euros - Cost of replacement display from the IPC shop: 89.00 euros

Christian Kopf

Manufacturers often replace complete modules – for example the mainboard – even with minor defects. At IPC Computer, repairs are targeted. The technician looks at what should be replaced and repaired in a sensible way in order to offer a cost-effective repair solution for the customer.

In contrast, manufacturers charge €400 to €800 for a new mainboard.
