Framework grounding issues when charging?

Framework Laptop 13
1

Hi. I’ve just recently noticed with my batch 4 framework that the chassis feels electric when charging, and physically hurts when touching the edge or corners. Has anyone else noticed anything similar?

Stop using the laptop IMMEDIATELY. Contact support. This is a potential major risk to health.

Thanks for the heads up. I didn’t realize the risks. I’ll be contacting them for sure asap.

I’m using a 100W multi-US charger using an adapter to work with Korean outlets. The multi-charger only has two flat prongs, so it doesn’t seem grounded.

If I use an adapter with Korean ground connectors, the electric feeling disappears.

It looks like the issue might just be the adapter I was using then.

I’ll update yall once I get this sorted out.

Okay so this is probably not Framework’s fault. Get rid of the non-grounded charger, those things are unsafe and should never be used.

Yeah. You seem to be right. I switched the adapter to one that has Korean Grounding contact pins and the electric feeling is gone when using the same 100W charger.

Thanks for the heads up! Case closed!

How would you test AC with a USB-C connector?

This sounds like a bad idea

Note that unless the wiring in your home is way wrong, there is unlikely to be a safety issue. The Framework Power Adapter is grounded deliberately to avoid this scenario though where an aluminum chassis laptop feels “tingley”. If you instead use an ungrounded power adapter though, you could experience it. Here’s a knowledge base article from another notebook maker with some detail on this: Information about the mild tingling sensation - Lenovo Support US

Thank you for all for the information, guys.
For clarification, I only have a US plug for a high-wattage charger, and they do not work with Korean outlets.

The tingling feeling is no longer present using an adapter with ground contact pins. I’ll be looking for a Korean charger for the long term, and this will only be a temporary solution.

I don’t think anyone manufactures USB PD chargers that aren’t universal (i.e. 100-240v)

You can use a grounded charger at home, and a more compact ungrounded charger when traveling.
