2Answers. It is OK for the UPS to be on the whole time. In fact, your UPS will last longer and be more reliable if it is not shut off regularly. (Especially if the UPS has a small deep cell battery.) An extremely minute amount of electricity will be consumed by the UPS - no differently than the battery of a laptop if it is always left plugged in.Topower on, a PSU requires that the motherboard shorts out two pins in the ATX power supply cable. If this is not properly done, then the PSU will not power on. Hence the reason for the power on
Waterhitting any of your components isn't really too much of an issue while the rig is turned off. The minute you send electricity through it is where the issue arises. Any water that got inside the PSU itself would be more difficult to dry out. When you turned the rig on, it was likely still wet/damp inside.
Theone chip responsible is that ITE chip. It controls all the power on/off , startup of voltage regulation, sends the power good signal to the supply, etc. The only interaction it has with the bios is the bios can tell that chip to turn power off, but it can't stop it from turning off power via the hardware switch.
Thesame problem may arise from the PSU (power supply unit) if it is unable to deliver 5V or 12V to power your fan. The PSU (power supply unit) for laptops is typically built into the motherboard. Keep in mind that when the CPU temperatures are low or you are not utilizing any power-intensive programs, the CPU fan will generally cease to spin
ThePSU needs a connection to the motherboard to be told to turn on. When you press the power button on your case, it jumps the green wire to a ground, telling the PSU to turn on. When this "jump" is broken, the PSU shuts off. The green wire on ATX plug is the "power on" line and is pin #14. The standard ATX plug will also have seven
However crashes often require turning off the PC to recover and that action, on its own, generates "improperly shut down" errors. However as a matter of elimination: Try running Windows' built in troubleshooters. The troubleshooters may find and fix something. Also apply "sfc /scannow" via the Command Prompt.
