    Hi fellow 15x V8 owners! I just got mine last week (what? one year after the release date and at the moment they released a new version??) Well after seeing what the next model will bring I decided to take this one. More reviews and solutions, better heat management (that RTX will sure bring some extra heat with it), better os same performance, lower price, ...

    Now I haven't found any hardware problem with this laptop related to keyboard, screen or anything like that. However, I do have an electrical problem. The chassis is made from conductive materials and I literally feel that. When I put my feet on the ground I am grounded so the laptop gives me electrical shocks now and then, through the chassis and through my guitar (when plugged in). Not big shocks obviously but obviously noticeable, comparing it to a needle prick. When I lift my feet off the ground this issue is gone. No vibrating feeling when rubbing the chassis and no shocks. So it is a grounding issue I think. I read that Gigabyte changed their chargers somewhere mid last year, is this the reason why??

    Hope to find some answers on this one...

    My gf's MacBook air had this issue, so scary. We had to replace the fatherc to get it fixed.

    Edit: Charger* not fatherc, strange typo sorry.

    That's your home grounding, because the chasis of the laptop is metal it will conduct stray electricity thru your body.

    Does it only happen when the guitar is plugged in? Could be an issue there.

    Is your charger properly grounded? If you're in the US, that means the third, round prong is actually plugged in. Some people use a 3-wire to 2-wire block for older homes or extension cords, thats bad, don't do that.

    How do you plug in your guitar? If you do it direct with a cable without any audio interface in between, you risk damaging your motherboard. The impendance is way different. If you do it with an interface connected. then you have grounding issues.

    No happens without guitar as well when my bare feet are on the ground and I'm touching the chassis you can feel the 'vibrations'. Actually a second laptop we have also has it (metal chassis) so I think it's related to the grounding in the house. It is in Indonesia...

    There is no audio interface connected in between because it is a Rocksmith cable that goes straight into the USB port: https://www.amazon.com/Rocksmith-Audio-Cable-Ubisoft-Not-Specified/dp/B005OSFUZI

    I guess the proper impedance converting happens inside this cable??
