Device fails to power up after losing electricity and remains inactive.
I consider a failing PSU, unstable motherboard, or defective power switch. I’d begin by attempting a jump start on the PSU and verify if the problem persists under proper voltage conditions. This helps determine if the issue lies with the power switch or the board. The specific PSU model isn’t mentioned—some are prone to using low-quality capacitors. A rapidly draining CMOS battery seems unlikely, but disabling the built-in switch doesn’t guarantee protection against voltage fluctuations. If this concern is widespread in your region, investing in a suitable UPS would be wise. 850-1000VA typically covers most setups; some may require up to 1500VA.

I own a 450 watt YAMA brand PSU. The PC was built in 2011 if you care. It wasn't the switch; I shorted the power pins and it worked similarly. Initially I thought the PSU might be the issue, but it seems to function when turned on, and Windows runs smoothly as long as it starts up. It almost felt like the BIOS was malfunctioning when I unplugged the machine, which is why a forced reset helped it boot. Probably just my guess, but I’m thinking a replacement CMOS battery could help since they’re inexpensive and there’s a chance the unit is faulty.
Thank you. I'll proceed with the replacement soon. I'll indicate the thread as solved once it functions correctly.
