i recently received my Teclast F7 128GB Notebook an everything is/was fine (except from 1 dead Pixel) but today i noticed, that if the Laptop is fully charged and plugged in the surface is electrically charged. You can feel it by touching the surface of the frame it tickles and makes a weird sound. Does anyone know whats wrong with my build, should i contact Gearbest and hope to get an answer?.
