Pressing the power button causes the PC to switch on, then shut down and restart itself.
The system cycles between power states after pressing the power button, showing the UEFI/BIOS screen and allowing you to save settings before returning to normal operation. This behavior suggests a temporary configuration issue or hardware reset.
Ensure your boot configuration is correct. Clearing the BIOS often resets everything, so it may restart normally afterward. Your system might not save settings, possibly requiring a new CMOS battery replacement.
You believe the BIOS battery might be damaged, affecting charge retention and causing boot issues. Could this lead to the PC shutting down and then restarting? Also, if the problem lies with the BIOS battery, it would likely be a cost-effective fix compared to replacing the PSU or motherboard.
When updating bios or clearing settings, the system often jumps past the main screen and restarts, recognizing the boot drive. This behavior might differ from yours. If you see LED indicators fading after power-off, that could be a clue, though it may not be the sole reason.
It seems the system is stuck in a dead state. After entering BIOS, there’s no need to modify settings unless you suspect hardware issues. If the machine fails to boot even after replacing the power supply unit, the problem likely lies with the battery or internal components.
It seems like you're suggesting it's probably the best explanation based on his statements.
Both of you are completely correct. I just swapped the battery and it seems okay now. Appreciate the help!
