Broken Repaired. The 5 Most Common Notebook Defects Caused by Improper Repair Attempts

Notebook defects are sometimes homemade. It is hard to believe, but a not small percentage of the defective notebooks that reach our specialist notebook workshop have already suffered a long period of suffering. Often, attempts to repair notebook defects by laypeople or self-proclaimed "specialist workshops" cause further and often very serious damage to the notebooks.
In the following, we therefore list what the sometimes strange self-repair attempt damage statistics mean here. In the following, you will find out which work on the notebook you should be particularly careful when you want to lend a hand and why a croissant and a cup of coffee can sometimes help.

Most Common Notebook Defects Caused

Broken Repaired. The 5 Most Common Notebook Defects Caused by Improper Repair Attempts.

1. Improper assembly of notebooks

Often important screw connections are missing or existing screws were inserted in the wrong place when reassembling the notebook, so that some of the cases no longer close properly. Long-term mechanical damage is often the cause. Components are often damaged as a result and have to be replaced. In some cases, cables are also disconnected, as the following picture shows.

2. Destruction of the display control on the mainboard when trying to replace the LCD module.

If the necessary caution is not taken when plugging in or unplugging the display connector on the mainboard, short circuits are often the result, which cause further damage. This usually happens with devices with an internal battery that cannot be easily unplugged. 
As a result, the parts and components of the notebook are live when attempting to repair. In the simplest case, only one fuse suffers damage, but this often results in serious damage to the mainboard, so that an expensive mainboard repair becomes necessary, including a necessary mainboard replacement.

3. Damage to connectors.

There are numerous variants of connectors that provide the connection of a wide variety of components and assemblies to the notebook. Most of them can be opened, but there are also connectors that slide open. The variants are as diverse as the notebook brands themselves. If you don't know how to turn the connector open and close, it is usually the bracket to the Locking the cable, which then tear off. 
But we've also had notebooks here that have reached us with connectors completely torn from the mainboard. Usually these then have to be replaced. This means first desoldering the connector and then soldering a new connector onto the mainboard. Obtaining exactly the right spare part is often the more difficult part of this notebook repair. In the case of very rare connectors that cannot be procured, a mainboard may even be replaced.

4. Tearing off cable connections in the event of improper notebook disassembly causes further notebook defects.

When dismantling a notebook, cable connections, e.g. to the touchpad, keyboard or USB or LED boards, are often torn off. When lifting the top case, it is often necessary to proceed very carefully and after a maximum of half the stroke, the corresponding cables must first be disconnected from the connections provided. If this does not happen, these cables often tear off.

5. Mainboard damage due to amateur mainboard soldering.

Special "specialists" sometimes even try their hand at soldering the mainboard itself. In most cases, this goes so badly that the mainboards can no longer be saved. Unfortunately, in many forums there are dubious repair instructions that deal with hot air soldering technology. What is forgotten is that a lot of experience is necessary here in order to be able to guarantee a professional execution. We had already seen the strangest cases.

Suggested solution: a croissant for the benefit of the defective notebook.

We have even seen a tip for warming up the notebook mainboard in the oven. Incidentally, after this measure, a defective graphics chip should work again. Our recommendation: Please do NOT copy it. If you want to put something in the oven, we recommend z. B. a delicious croissant, which can then be enjoyed together with a good cup of coffee when looking for a reputable notebook workshop.
