Keep the computer connected to the earth ground. Without 1 MOhm resistor
Either use a bipolar switch, opening BOTH wires connected to the mains
outlet, but keeping the ground connected
Or unplug the cord and connect the chassis to the ground with a wire and two
alligator clamps.
Connect yourself with a wristwatch to the computer case through 1 MOhm
This is very important also: Avoid all kind of insulation between the
computer and you. Use dissipative materials instead (conductive but with a
high resistivity). Wood isn't good as well as plastic soils or carpet. For
the floor, tiles are good, concrete as well, preferably the table shall also
be covered with dissipative material (conductive rubber).
In case you can't have dissipative material to cover the table, this isn't a
big problem as far as everything is grounded or discharged prior to opening
and handling.
