I've recently set up a laptop in my room to record demos and such.
I've noticed, when I touch my laptop casing (when it's plugged in) and touch the strings of my guitar (Godin Session plugged into a Blackstar HT1 combo) with the back of my hand I get an electric shock. This only happens on my forearms or back of my hand, not when I'm fretting strings...
The guitar buzzes when not touching the strings normally so I'm assuming this means there's an issue with the grounding of the guitar?
What's strange is, with the guitar buzzing away, as soon as I touch the laptop the buzz gets louder.
Not sure what's occurring here, if it's the guitar, amp or laptop that has an issue.
Any help would be very much appreciated.
Cheers,
Shaun

It's generally so slight though that's it well within limits and not a safety issue as long as you are using a real charger as not some cheap Chinese knockoff from Amazon or Ebay
Yours will be a USB C charger though rather than a Magsafe which is a whole different ball game ... it’s a very complex system of voltage and current hand shaking ... it does have a ground but it’s not always connected to mains ground . Often the only thing between the secondary side of the switch mode power supply and the primary is the Opto isolators So you’re not in any danger it’s just annoying sometimes
