Im new to this bios stuff can you link me to a duke approved bios dumper/flasher? ???

i have this board wich boots up with high fan spin and shuts down. after inspecting it i can see someone else has worked on it due to the bios chip being badly soldered. im wondering if they replaced the bios chip without any knowledge of reprogramming that needs to be done? is it possible to...

5v_s4 is present but not power cycling. it looks like it may have been water damaged before due to slight corrosion on test pads.

ohh too low.

0.260 amps goes down to 0.060 amps

yes when connected to my benchtop power supply amperage is high then goes down seems like odd behavior not sure if that may be a clue to what could be wrong. it does look like the board has been worked on before seems like isl was replaced and a trace near the smc was blown re attached it...

yes its there at 8.16v

replaced isl now im not getting pm_slp_s4l board will not turn on.

The board is missing PP5V_S4RS3 and PM_SLP_S4_L is 0.064v i also notice that when the board is connected to a power supply it goes from 270amps then goes down to 60amps. where should I begin.

So the issue started with slow charge. pin 17/18 and 27/28 checked out so i decided to replace the isl but now i only get a green light no charge indication. i checked the smc data line resistors and theyre fine the board will run off the battery and charger but will shut off if the charger is...

My multimeter is over by .3 so i usually get 5.3v on 5v lines so thats why i asked it would mean im probably arounf 4.94? i shall forget i suppose.

date code is 11/13 i have no cpu vcore not sure if this is normal but u5400,u5410 and u5430 are all outputting around 0.30-0.50v also vcc of u7400 is only getting 4.97v it should be 5v right?

smc area looks the most affected by water.

yes liquid damage those resistors are fine.

decided to just leave BIL unconnected and its been functioning fine. ill leave as is.

yes all_sys is 3.3v

now its 11.77v on ppbus with battery connected no charge indication and BIL cable connected on ppbus. 12.62v with BIL disconnected no charge indication while battery connected on ppbus. 11.85 without Bil connected, charger unplugged and battery connected on ppbus. 12.28v without battery...

12.26v without battery 12.55 with battery. once again its charging like normal and has not stopped for a longer period. removed charger and reconnected ppbus stays at 12.58v but no orange light with battery still plugged in. unplugged charger again and reconnected charge indication is back...

u7000 17/18=3.6 ohm 27/28=20.9 ohm i think that circuit is good. the next issue i found was cpuvcore is not getting any voltage after doing some digging i found that CPUIMVP_BOOT1 on u7400 is only outputting 4.85v LGate and UGate output nothing. ive already tried replacing u7400 but results are...

No doesnt work either way. It has suddenly stopped charging while off again. would eradicating the bill connector rid the issue?
