Why do I feel a stinging or tingling in my hands when I'm working on my laptop and grounded?
Ungrounded laptops (without a three prong power cord) can generate significant electric fields. Some people will feel sensations while they are grounded and working on the computer. If the feeling is uncomfortable, we recommend several options:
- Don’t ground yourself while using the computer plugged in.
- Ground yourself only when the computer is operating on battery mode.
- Place the laptop directly on an Earthing® Universal Mat to ground the computer.
