I have a dead FX505D, motherboard FX505DD REV 2.0 , the owner replaced the cmos using a screwdriver and he touched something on the board, since then the laptop its not starting, i have managed to see that U8800 (BQ24780SRUYR) charging IC is getting hot under a thermal camera , i have desoldered it but the laptop still doesn't power on, i also have no voltage at power connector on the board. I also replaced the U8800 but still no power. What should i check next?
