I was interrupted and accidentally click "Send" before I could finish typing
my first post below. Anyway, I agree with Tom. 100%. In fact Kenny Parks'
and Joe Lore's suggestions were what I had in mind to post. You guys have
covered the "BIOS", "Wake up LAN" "Keyboard" & "Mouse" which would be the
first choice to check.
However, 2 weeks ago we run into a very interesting incident in our shop
very early in the morning. A lady called and inquired about her computer
(one of those famous brands). Her question was, "does a computer starts up
on its own?" Jokingly, I said "not, if it's not plugged into your wall
outlet." I learned: she had a P4 1.8 GHz Win98 256MB system. After using
at night, said she would go to the Windows auto shutdown and press the power
switch on the monitor, off. So, I said okay... all system should be OFF.
One night she woke up with the sound of gurgling and mumbling (from Windows
"Underwater" screen saver)from the speakers on her PC. Her room was dark
but noticed her CPU's red light was ON. The poor lady said she spent that
night with her behind up in the air and her head buried on her pillow,
scared to death. She thought there was a ghost in her room!! She strongly
believed of a ghost in the house since that was not the first time it
happened. 3 times, she said and always happen in the middle of the night.
To make this short, we checked her system's BIOS/CMOS, traced for switches
or possible jumpers on the motherboard that could trigger a "WakeUp" but
didn't find any. We even thought it was a power supply defect. Then we
learned she does not use surge protector. We sold her an 1800 Joules unit
and I cross my fingers as she walked away. The last time she called, she
left a message on the machine telling us "that thing you sold me for my
computer (the surge protector) must have driven the ghost away! When my
computer is off, now it stays off!"
Far fetch? Yes, I know it is. I also found out the power company's
substation in our town swaps breakers at exactly 1:00 AM every night. When
this happen, would a surge cause a momentary contact on her PC's switch?
Maybe a coincidence but I thought hmmm, possibility? Well, it worked. (If
all else fail, Barb may need to have an exorcism done in her house?) You
all have a pleasant day!
