> Apple support are utterly fucking useless and don't know about this.
That particular support person/bot may not have but the company absolutely does
I've never had this happen with a laptop but as a musician I've been zapped by a microphone a bunch... not an infrequent occurrence if you play electric guitar and sing at the same time. Twice in the past year I've been hit during soundcheck at a gig because of bad grounding at a venue. Last time my solution was to plug everything into the same outlet via a power strip but I invariably end up off-kilter for a few minutes after being electrocuted through my mouth as I'm about to play :-(
I'm startled they put a metal earth pin on the type-G adapter for that plug that does nothing.
That's additional cost just to make it look like it's grounded when it's not.
This also happens with iPhones. And under the right circumstances you can feel the same tingling sensation on skin contact as well if the other person is holding a plugged in iPhone.
Shouldn't this be a UL/CE certification issue?
I have no expertise in this: but it could be one of the cells in the battery is performing worse than the rest. The way charging works in a pack is that it measures all 4 cells for instance, and if one is higher than the others it discharges that one only, then continues on charging them all at once, then periodically checks again
I get this sometimes, but not all of the time on my newish (6 month) Asus 14 laptop with a UK 3-pin to mains power supply. And I've had it with other laptops in the UK. It's mysterious, but don't think it is going to kill you.
My frustratingly rubbish M1 Air does this, amongst many other odd and annoying things. But hey... what are the alternatives?
This is why I avoid aluminum laptops. Too many plugs aren't properly grounded and the tingling annoys me to no end.
I don't notice this in North America but I did notice it in Europe. Using the 2 prong in both places.
Noticed it in Asia but Not Japan. Always knew it was a grounding issue.
i have had this issue and realized i was basically getting a low key elec shock every time i had the power plugged into my mac; turned out it was the apple wall wart power brick; using a different one ended the constant elec pulse shocking effect. (at first i thought it was the shitty fraying usb-c cables apple provides which turn yellow and the plastic breaks apart after 6months to a year - nope! that thing is fine).
it’s a design decision because some people like myself actually like the light throbbing
This is a widespread and well documented phenomenon.
