Minisforum NAB9 Quality Notice
We have identified a potential issue affecting some NAB9 Mini PC units manufactured between September 19, 2024, and March 14, 2025. In extreme cases, these devices may experience startup failures, specifically abnormal shutdowns or failure to power on after a normal shutdown, with no indicator lights turning on. Our investigation revealed that this issue is due to a mix-up in the capacitor materials supplied by our vendor for this batch.
Important: Only customers with NAB9 units that fall within the specified SN range and experience the startup issue need to contact us for a replacement.
At Minisforum, we deeply value your trust and are committed to making things right. We've already implemented enhanced quality control measures to prevent similar occurrences in the future.
To ensure every customer receives the premium experience they deserve, we are offering comprehensive support for affected devices.
How to Check if Your NAB9 is Affected:
Customers can check if their NAB9 may be from the affected batch by inspecting the serial number (SN) located on the bottom of the device. If the third to fifth characters of the SN number fall within the following ranges: 386 to 526 or 017 to 117, and you are experiencing the startup issue described above, your unit may be affected. Please refer to the following figure.
