USB Ground Cord
Add Grounding to Your Laptop
Most laptops are not grounded, even when working off plug-in power. Ungrounded electronics may emit high electric fields or raise Body Voltage. Adding grounding could be the answer. This 12 foot ground cord plugs right into the USB port and makes contact with the laptop's chassis. The other end plugs into a grounded wall outlet (North American plug style). Simple and effective, as recommended by Michael Neuert.
Caution: Use an outlet tester to check your outlet for proper grounding before connecting a laptop to ground. Don't blame us if your outlet is not properly grounded!
