[ATTACH=JSON]{"data-align":"none","data-size":"medium","data-attachmentid":3527618}[/ATTACH] this one is in the ram slot region. and another one on the ram itself

Asus X515KA-EJ058W
Asus X515KA-EJ058W
SN N3N0CX079477106
CN Y7NC
MFD 2022-03
Board model :X415KA rev 3.0
problem: black screen just blinking leds
original extracted bin attached....but it is corrupted
i tried a lot of different versions....sometimes i came to the bios and even windows....but after restart dead again...very strange
with some version (which seems to be not the right...the board does not react to power switch)

i first thought theese coils are for the gpu and 2.5 ohms could be normal and searched for the error on other components
now i get a lot smarter

~0.25 ohms on ground which are my cables
~2.20 ohms on that coil
another coil around there has 0.25 Ohms...voltage injection there heats the pch also...Leave a comment:

i assume that the pch is shortet ?
the bios has no voltage. chip has 3v
so i injected 1v 2A there...
the only thing which is getting warm is the PCH chip besides the cpu
does it 100% mean the pch is shorted ? or can it be a component on the "other side" of the pch which is shorted, so the current is goiung through the pch and heating it ?
but i don´t find another component getting warm with the thermal camera.....so i think pch dead ?

if i re-extract the bios after flashing....i cont aopen then in uefitool !
the same with the original i extracted before i begin flashing the first time
so something seems to corrupt that bios again and again and again....but....i had a time, i could restart and restart and came everytime to the bios....strange...

theres no obvious short when taking the 400mA. only cpu gets warm...seems to work and get warm....but no picture etc.Leave a comment:

Asus X515KA not booting. after flashing bios sometimes i come there. but then dead again
hallo,
i have an asus X515KA-EJ058W here.
just both leds white...he battery blinking without battery connected
consuming ~400mA and tries to start but nothing happens but fan spinning if cpu gets warm
if i hold the power button it shuts down and consumes ~30mA i cant spot anything getting warm with thermal....the ec/sio a liiiitle but this is maybe normal beacause it is working ?
power on again is possible but again 400mA then and no picture.
now the really strange
i flashed bios (some version i found on the internet) and resoldered....sometimes... -
okay....i am actually wondering why my SDL/SDA on the IS9538H are 0V
in another thread here...sbd is measureing 3.3v which should be right
so maybe my sdl/sda bus is dead for any reason ?
i think i found a 3v3 regulator....i can measure it on some pins...but i don´t understand this component and can not find it anywhere
there are no 3.3v given to the coil !
don´t know where this voltage regulator i think is getting its comman from ?
there are a few of this components with different pin counts on the board. and the "under...Leave a comment:

newbie needs capacitor sizes. HP Spectre X360. schematic maybe available
hello, i am very new to laptop repair and generell electronics
i have a HP Spectre X360 Convertible 13 - ap0016ng
motherboard number DA0X36MBAE0 REV E
massive burned and shortet mosfets. after removing them still shortet in the i think "main power rail"
found a shorted capacitor. removed it and the short is gone.
i want to try a crazy repair which is hard because the mosfets are like welded on one side to the track. is there a method to get this loose ?
in this area another capacitor was shortet.
... -
i desoldered this guy.
wenn im testing everything is okay so far. but...with multimeter in diode mode im bringing it to ON positon. when i am then checking the drain and source....its first a short = good. but then the voltage increases. is this normal behavior from an p channel mosfet ? the n channel doesn´t show this behaviour to me i think ?
or is this a bad one...Leave a comment:

okay....i missunderstood the boot thing
i learned that it is necessary for the gate switching circuit for the mosfets. so normal that there is this voltage.
phew...okay..i have no acok and the mosfets are not triggered for some reason. i ordered new ones...but they aren´t send till today. i will check the old ones now and then put them back to the board...
okay, i think the short was maybe coming from my exzessive pointing with the multimeter needle.
today i changed the ISL9538H chip.- now i got 5v ldo there on pin 8 and 18 back
can sbd help me...Leave a comment:

today i changed the ISL9538H chip.- now i got 5v ldo there on pin 8 and 18 back
the freaky thing is..on BOOT1 i measure ~5v and BOOT2 ~4.7v
so to kill anny possibility...i just remoed the 4 MOSFETS. an it´s still there....where the hell is this voltage coming from ?
on another side i found the lenovo schematic....there is no other connection in it. i can´t see another connection on the board.
isl is changed.....or directly damaged again ? so that...Leave a comment:

can somebody help me with the schematic ?
pin 13 ASGATE of IS9548h is shortet to BOOT1
but i can´t find where ASGATE is connected to ?
i ordered the IS9548h and Mosfets AON6380. thes are the 4 ones
or do you mean the 2 before could be faulty too ? they seem to pass the input volatage perfectly... they are SM3335p
i think the ASGATE is wrong in my picture....got the picture from a youtube video ? in the datasheet its calld ADPS: Reverse output voltage feedback. Use a resistor divider externally to configure the reverse output voltage

WTF the capacitaor from boot1 measues at one side the realistic voltage of 4.7 between the mosfets. on the other side it has the strange 13Volts. then comes 0 orm resistor with 13 volts on each side an then the ISL chip
i think there is really a short of this side then ?...Leave a comment:

the boot1 voltage is crazy ?
it should be the same as Phase 1 ????
it is shorted to the next pin (Asgate) .....wtfLeave a comment:

i don´t know what happeneed but i get another reading now
i was wondering about the boot and phase values and searched for the capacitors....is this strange.
here are the updated readings ion the picture
the mosfets have crazy effects during measurement. some valueas are different if i change + and -
