Device fails to power up following an unexpected electricity interruption.
Hi, I experienced a power outage while using Blender. When electricity returned, I tried restarting it but received no response. No fans ran, and the LEDs didn<|pad|>. I reset the CMOS, unplugged the PSU, cleared the charge cycle, tried different outlets, but nothing worked. Any assistance would be really helpful, I have assignments coming up.
It might have happened before the outage or after power came back, causing a spike that damaged the PSU (or possibly blowing its internal fuse). Ideally, turning it off at the switch or unplugging it completely is a safer approach during any power disruption.
Hi, I fixed the problem. I unplugged the front panel IO and used a screwdriver to jump the circuit, which restored power. It looks like the surge damaged both my front panel and some fan headers. Luckily, there are no performance issues beyond the thermal throttle from lost intake fans. I’ll need to replace my motherboard.
That's quite an obscure failure mode I have to say, especially given the power button is usually wired straight through with nothing fancy to break.
