power off problem solved please
I am experiencing odd behavior during power off. The first symptom I
noticed was at the point during the power off sequence when normally the power would go completely off, the speakers made a noise like dit-dit-dit-dit in a slowing sequence that finally stopped. The dits started about 3/sec and ended up about every 2 seconds. This took about 10 seconds. Since it sounded like something spinning down, I opened the case, disconnected power to all the disks, and powered up (of course getting complaints about no system disk) and off. I observed the same behavior, and also noticed that the fans, which stopped while the dits were still going, were nudging slightly in sync with the dits. So it seems like some power is still going out after I hit the power off. If I physically unplug the computer or turn off the power supply switch (not the case switch, but the power supply switch itself on the back), then the noise stops immediately, but starts again when I plug-in/turn on. This time it doesn't stop until I cycle the case power again. I'm thinking this may be a power supply problem or possibly a motherboard problem. I don't know if improper control is being sent to the supply, or if the supply is misbehaving. I haven't observed rebooting that might be symptomatic of a failing supply. I don't have extra power supplies or motherboards around to test with. Any suggestions? |
