      Re: need argent help here please

      hot is coming... gaming laptop... does it switch to dedicated vga when on adapter and use intel vga when on battery ? that could be just one possible cause.
      second cause can be a gate mosfet not opening 100% and becoming hot or not making enought current go trough.
      also other cause possible, butr for now that's the 2 most common problems.

          No issues with Only Battery present or why mentioning the Part with Adapter present?
