For some reason I can't open any of the pictures you uploaded.
Kind of doubtful there is "redundancy" and you can afford to just straight up lose a component without it having a functional impact.
I assume manufacturers would prefer to get a better component that is guaranteed to last as long as the warranty rather than put many components in parallel and just hope they are lucky not to get many failing components at the same time that are supposed to be redundant.
I asked ChatGPT about this as I was curious about the design of modern motherboard and redundancy.
Take that with a grain of salt obviously :
In some cases, motherboard manufacturers may design circuits with redundant or parallel components, but this is not the norm for most consumer-grade motherboards. Instead, multiple components, such as MOSFETs, are often used in parallel to handle higher current loads or improve power delivery efficiency, rather than as a backup in case of failure.
Key Points to Consider:
- Parallel MOSFETs in VRMs (Voltage Regulator Modules):
Modern motherboards often use multiple MOSFETs in parallel within the VRM section to distribute the load. This improves thermal performance and ensures stable power delivery to the CPU, GPU, or RAM.
If one MOSFET is removed or fails, the others may compensate temporarily, but this could lead to overheating or instability, especially under high load.
- Redundancy for Reliability:
True redundancy, where one component is a backup for another, is uncommon in consumer motherboards due to cost constraints. It is more likely to be found in high-end server motherboards or mission-critical systems.
- The System Boots, But Risks Remain:
The system may still boot because the remaining MOSFETs are compensating for the missing one. However, this can stress the remaining components, potentially leading to overheating, instability, or premature failure.
- Importance of the Detached MOSFET's Location:
If the detached MOSFET was part of the VRM or another critical circuit, its absence could reduce power delivery efficiency and system stability. If it was part of a less critical section, the impact might be minimal.
- Repair is Recommended:
Even if the system appears to work, running it with a missing MOSFET is risky. The component should be re-soldered or the motherboard replaced to ensure long-term reliability.
Advice for the Person:
If they suspect a detached MOSFET:
Identify its exact role on the motherboard (consult the schematic or motherboard layout if available).
Avoid stressing the system until the issue is resolved.
Seek professional repair to reattach the component if they lack the tools or expertise to do so.
While the system might seem fine for now, ignoring the issue could lead to further damage or failure.
