Computer that gives electric shocks

Hello,
I've been encountering a problem with my laptop for a while now.
At certain times (randomly), everything connected to my laptop (HDMI cable, USB ports) gives me pretty strong electric shocks.
The thing is, if it were just the USB ports, it wouldn't be a problem for me.
But since I'm used to plugging a keyboard into my computer, it also becomes electrified if I touch the metal parts of it.

I've tried to see if I'm not plugging in too many things to my computer, but no, even with just one cable connected, I've already received electric shocks.

I've also checked to see if it was the charger, but even when it's unplugged, the problem can still occur.

So, it's a bit long, but if you have any solutions, that would be super cool!

PC ref: asus rog strix G712L

    Hello,

    To make this PC disappear and secure it, you need to connect it to a ground socket... If your socket doesn't have a ground, you should connect it with a ground wire to a metallic part of the PC, like the USB port, VGA or HDMI socket, etc.

    If you have a real electrical leak, your residual current device will likely trip; this indicates a ground fault in your installations that needs to be resolved...

    These faults can come from your house... Radiators, washing machines, toasters, etc., and this possibly weak current travels along the ground line to all the devices, and you feel it at your PC...

    Often, grounds do not go to all devices because they have "Double insulation" (no ground)... but also the stacking of power strips causes an abnormal break in the line.. (not legit)

    Additionally, HDMI cables, printers, scanners, projectors, and wired LAN connections have a ground wire that carries the electrical shock back to your PC...

    Personally, I've seen a shielding sleeve literally burned and melted from a ground return (abnormal)

    You should also know that not all wires necessarily pass through the protection of the residual current devices... An example: the coaxial cable coming from the satellite dish... it should... but it works perfectly well without it... and avoids lightning strikes.

    Hello.

    If the problem persists with the transformer unplugged, it is much more likely to be static electricity.

    It's unpleasant but harmless.

    Try it without shoes and with a wooden chair.

    In this dry season, you may have a static electricity problem...
    It's difficult to pinpoint because there are so many possible causes... It could come from your shoes, the chair you are sitting on, or your clothes...

      Hi

      During a drought, the grounding of homes can also become defective; one faulty device in a building and all the occupants risk electrocution.

      The symptom is the same, you get a shock, but the risk is not the same.

    Hello

    it's been a while:don't wait, it's dangerous

    You probably have an electrical fault in one of your devices, plus a grounding issue with the 230v connection of the PC.

    Start by separating the PC and accessories from other devices using a few high-quality 16A power strips with grounding, but don't hesitate to call an electrician because this is a risky situation for health, it is essential to eliminate the defective device and get it repaired as well.

    • Restore the ground circuit for all devices in the house
    • Find and repair the faulty device
