Can you post your bios + EC backup . -
Re: HP envy 15-j037el intel I7 bios

Re: HP envy 15-j037el intel I7 bios
I checked and on page is the affected area, the supply voltage of the U4701 bios component is indicated as P3V3A while that of Ec U301 is P3V3A. The source of P3V3A is Q7003 which is not powered but before there is still U6100 which has not shown pinout. He could be the culpritComment
