I bought this notebook computer in September, 2001. It is one
which has to be shutdown first before turning off the power switch.
The computer knows if this shutdown procedure is followed lest it
does extra steps during startup. So what has a computer got to do
with the paranormal? Well, during shutdown the read/write head of
the hard drive makes some rapid knocking sounds, i.e., di-dit,
di-di-dit, di-di-di-dit, and then a short "IT IS NOW SAFE TO SWITCH
YOUR COMPUTER POWER OFF " display on the screen before the screen
goes black. Long before I even planned on buying a computer,
perhaps over a year or so, I had been hearing this exact knocking
sound on several different occasions almost regularly just before
going to bed after staying up late with my books at night (usually
during the wee hours in the morning). The sound came from outside
the window of my apartment. Every time I heard it I would wonder
what it was!
So what was the sound I had been hearing? Was it some similar sound
made by a woodpecker, a toy, water hammer in a plumbing some place,
or a lunatic knocking on wood, plastic or steel, or was it a sound
from etc.? The answer is a big NO. The knocking sound is a sound
like no other, made by this kind of computer only. There is nothing
similar. Was it the sound from an identical or similar computer
being shutdown elsewhere in the building or on the street? This is
the closest possibility, but it could not have been because the
sound from the notebook is only audible within three to five feet
from the computer in an absolutely quiet surroundings. The other
apartments in the building and the street are several feet away
from my window and, needless to mention, the rooms are sealed in
storm windows and acoustic insulations.
Since I met and bought my notebook computer, I never heard again
the knocking sound from outside the window. Nowadays I am busy
almost every night with this laptop till the wee hours in the
morning. When I shut it down, it makes the unique knocking sound
that I had been hearing even before I bought this computer.
Now I know for certain what I had been hearing during those wee
hours in the morning long before I met this notebook..... It was
this notebook making those weird sounds while shutting down
somewhere. Probably this notebook knew I was going to own it.
The time to have this occurrence on record is lagging way behind my
notebook which went ahead of its time!
