CyberGuys
www.cyberguys.com has a neat catalog. They have
a short green cable that looks like a computer power cord,
except it only has one wire, the ground wire. You unplug
the power cord at the back of the computer, insert the green
ground and plug it all back together. The computer is then
grounded to the house electrical system giving a path for
extra electrons to flow to ground. A well designed computer
case will act as a capacitor and can absorb a rather large
amount of free electrons. But there still could be a high
voltage stored on the computer.
Depending on the humidity, the kind of clothes you're
wearing, your shoes, socks and the floor and furniture, the
electrons may dissipate quickly or they may sit there as
static electricity. In dry conditions without a path to an
adequate ground the voltage can be in the thousands. Since
modern chips operate at or less than 3 volts (some are
around 1.5 volts now) it is easy to short out a chip if the
path to ground is through a chip circuit.
You can find all kinds of ESD grounding straps in the
CyberGuys catalog or at your local electronics hobby store.
To learn more, Google for ESD, electrostatic control, static
electricity + computers and you'll have a lot of info.

| Thanks for that explanation, I will also pass this on to
my grandkids. They
| never worried about this at all. I keep telling them to be
careful about
| this subject, but I guess I kept buying new stuff for
them, when they
| screwed something up. I just can't do the tuff love stuff.
Many thanks again
| for the kind and generous advise.........Peter
