Dell Inspiron charing options. this is weird.

I was away with my family this weekend and took my laptop with me. So I plug in the notebook for the night after using it for awhile and have this funny "sensation" when I was charinging it on the right hand side of the machine where my wrist stays.  Like tingly sensation but not quite.  In order to feel it you have to move your finger across the notebook.  So I pulled out the charger and it stopped.  

 

I then tried with a otterbox USB C charging block and apple cord I have to charging both our phones at the same time.  That charging solution produced the same "sensation".  I get back home and plug into the original charging block and cable and low and behold, no "sensation".  

 

Can anyone give any reasons why two other chargers would do this and one does not?  I have another dell laptop charger in my office I have to try as well.

Electrical/grounding issue. Make sure that you use a grounded power adapter (three prongs into the outlet), this will almost always "solve" the problem. It's also possible that the hotel (or wherever you were away-from-home) somehow doesn't have proper grounding, so a grounded adapter helps when you are at home but not at the hotel.

 

I've also experienced the "tingling" before, but this issue is most obvious to me when it manifests itself as a "background hum" when I plug 3.5mm headphones into the laptop. I never get this with a grounded power adapter but I get it with a two-prong adapter ... on some outlets, but not others. This actually happens with a variety of devices, including my laptop, a portable monitor with audio output, and my Nintendo Switch.

 

Unfortunately, most USB-C chargers cheap out and don't provide grounding. One option is to use the Apple ones with the detachable outlet-side end piece, and then connect it to their grounded extension cable.

Nailed it for sure. Both the chargers I had were 2 prong. One was the apple charger though.  But 100 percent grounding now that I think about it.  And the hotel probably didn't help matters either.
