CMOS battery problem


Desktop PC stops working for no apparent reason. Doesn’t power on.


Tested power supply, power button, CPU, RAM, all fine.


CMOS battery! PC would boot if the battery was removed. With the battery┬áinserted the system wouldn’t power on. Replaced the CMOS battery, but the problem persisted. Perhaps there is corrosion somewhere near the battery socket which causes this. I just left the battery out.
