what do you mean ckt? unit has power I suppose so. but fan does not spin. Leds are light on power and on switch button. still need bios file. hope someon has. thanks
update on this. I already reprogram bios using aanan file but still no go. I also replaced nec tokin but same issue. Laptop turns on but cpu fan does not spin and gives no display on screen. Do you think this is related to video chip which is an Nvidia N10m?
hmm tried a soft reflow on gpu but still no cpu fan spin. I did check on voltages and found no voltage on Pin no.1 and no.3 of J3 fan connector. Also notice there's no voltage on L11 3.3v and L10 5v of TPS 51125 ic. This should be my Alw voltages right?
Pin 8 vreg3 3v is present
pin 17 vereg5 5v is present
Test done only on charger without processor, memory and cmos battery. Having hard time locating components as only limited prints on the board
