Actually it does protect the thinkpad. The ground is
connected to the thinkpad frame through a 1M resistor
to protect it from static discharges, such as sparks
from walking across a carpet, static from clothing,
lightning, etc.
and drains the charge off to ground when you touch it
if you are statically charged or if there is a
lightning strike on the phone line or whatever.
