It happened for me also, 3 months after the warranty expired. I suspect that the CPUs used in the TS-653B had a problem that should have been fixed with a BIOS upgrade, but I've never got notified from QNAP that I should proceed with this offline operation. Probably the CPUs will not crash unless the usage pattern of the device is somehow special..If you google for it (try webarchive), you might still find in the initial Product Change Notification (PCN117143-00) from Intel, that it was stated:Summary of Changes from B-1 to F-1 Stepping:Intel identified an issue with the Low Pin Count (LPC), Real Time Clock (RTC), SD Card interfaces on Intel®Celeron® N3350, J3355, J3455 processors and Intel® Pentium® N4200 processor resulting in degradation of thesesignals at a rate higher than Intel's quality goals after multiple years in service.For a comprehensive list of changes, refer to these documents:• Intel Apollo Lake / Apollo Lake - I Dashboard - Lite (RDC# 573991)• Intel Pentium® Processor N4200 and Celeron® Processors J3355, J3455 & N3350 Specification updateAddendum - NDA (RDC# 601134)Have you used on your NAS applications that used the CPU intensively? I'm asking because my NAS was running services in docker and virtual machines, keeping the CPU usage most of the time at maximum. If you find a source, I'm interested also in a replacement of the MB of my old 653B, I've spend some weeks/months looking on ebay for it, but no luck.In the meantime I've bought the new model TS-653D but with 3 years warranty and I've bought extra 2 years from the retailer (QNAP is asking an enormous amount of money for their +2 year warranty expansion). I will try to push this unit to the limit, at least to crash it while it's still in the warranty.Regards!
