Re: Dell Vostro 3560 no power :'(
I guess the problem is from power crt,

Re: Dell Vostro 3560 no power :'(
Mr/highpulse,
Thank u but i cant do anything with this common test just be more specific like what pin or component to test from schematic i attached to main post im noob u know
>> about SIO on mobo is >> ENE KB9012QF-A3 <<
>> about ROM chip already programmed with correct and working bios so i dont need new one :-)
>> EXACT board code : QCL00 LA-8241P Rev:1.0 (A00)

Re: Dell Vostro 3560 no power :'(
This tests when QZ3 out board now
QZ7 : (D 3.15v) (G 0v) (S 0v)
QZ9 : (D 0v) (G 5v) (S 0v)
QZ4 : (D 2.66v) (G 1.3) (S 0v)
QZ3 removed, voltages pins : (D 3v) (G 2.66v) (S 0v)
..................
QZ3 (on board) : (D 3.15v) (G 3v) (S 1.6v)Last edited by AGmR; 12-01-2016, 07:24 PM.

Re: Dell Vostro 3560 no power :'(
oh yes thats right QZ9 G= 5v
>> QZ10 D=1.3v & G= 2.3v
good explain about G QZ3 VD i got the point now ...Last edited by AGmR; 12-01-2016, 06:37 PM.

Re: Dell Vostro 3560 no power :'(
oh im sry i removed the 470k one on right though it was 1.5M and now i desoldered the another one on left
and measured it yes its around 1.5M, my bad sry...

Re: Dell Vostro 3560 no power :'(
So QZ3 it self is good (tested out board by method 6 measures and only one read >> cuz i just was know it before )
so on board pins 1-2-3 S = 0v, 4 G = 2.65v & 5-6-7-8 D = 3.15v
about resistor out board = .275M ohm ( i think its not this one should = 1.5M )Last edited by AGmR; 12-01-2016, 04:19 PM.

Re: Dell Vostro 3560 no power :'(
Here it is >> [url]https://www.dropbox.com/s/v93rjcihuau5v5m/Mobo.rar[/url] << HQ photos Front & Back side of mobo
that 390k resistor is the one supposed to be 0 omh or the 1.5m omh ?
where u have 390k u should have 1.5m
>> i dont know that just what i got
the one in the middle has 2 point connected ? if so that is the 0omh
>> yes thats right they r just points with 0 ohm
measuring in process ...Re: Dell Vostro 3560 no...

Re: Dell Vostro 3560 no power :'(
sry but u mean problem is qz4 gate or qz3 ? cuz the qz3 gate is 3v, so ..

Re: Dell Vostro 3560 no power :'(
I dont know what specifically they are cuz no write on board but i chose the closest one....

Re: Dell Vostro 3560 no power :'(
So all resistors measure gave me values around bios chips
and all in there places nothing moved
do u need values of each resistor ? or it is okLast edited by AGmR; 12-01-2016, 07:59 AM.

Re: Dell Vostro 3560 no power :'(
Yes 4MB & 2MB. yes i did, im very sure.
i will now and let u know..
yes i used hot air, but no nothing moved im sure
anyway i will check & let u know.

Re: Dell Vostro 3560 no power :'(
Yes Mr/meritosari good observation i think so also so here we go it's from mobo itself :/
Hello my friend im already bro have a SPI programmer + SOIC8 SOP8 Clip
so im already flashed both with original bios dumps now and i did it before so so many times before that happen so my friend its not from bios flashing
my kind regards to u :-)
Mr/dellxps
this is the bios chips zone (not taken by me) cuz i cant take a good photo with my mobile camera...

Re: Dell Vostro 3560 no power :'(
yes it was running so good before that shitty flashed i did
Mr/katfish, even if it was wrong bios or any some wrong hex code just written on bio chips mobo will just be so ok with power but i will get just beeps (i got that so many many times (my flash method from dos by command line) ) but this was flash bio with that insyde shitty original flashing program didnt have protect if the file bigger than the chip bios so it will keep flashing till BOOM on power.
I got the bios dump from vinafix (Vinafix.vn_Vostro 3560-A17)...

Re: Dell Vostro 3560 no power :'(
sry for late just take time to make sure measure is correct & thank you
Frist :before and while pressing on >> PL200 = 3.15V & PL201 = 4.95V
Second : 3.15V on pin 1, 2, 3 battery connector
Third : before and while pressing >> both chips on pin 1, 8 = 1.5V
my regards :-)

Re: Dell Vostro 3560 no power :'(
Someone gimme a hint plz , i have all necessary tools (solder iron , multimeter, hot air gun & even can buy replace components it's cheap)
i post link in above reply have all good quality pics for my mobo
but please any serious hint to measure in the name of GOD.

This is FullHD album photos for my mobo (LA-8241P)
its same just with dGPU Dell Inspiron 7520 model

Re: Dell Vostro 3560 no power :'(
yes Mr/diif they both readable on programmer out board i even erased and reprogramed them on the board but nothing happened same problem.Last edited by AGmR; 11-29-2016, 10:17 AM.

Re: Dell Vostro 3560 no power :'(
New things tried today :
desoldered both bio chips thought maybe they r bad or something
tested all fuses around power circuit with avometer they all good
same problem :/

Dell Vostro 3560 no power :'(
Hello everyone
My problem is i flashed unfortunately bios bigger than chip size ( yes i know im rly idiot) :/ then laptop shutdown suddenly in prosses with little power i mean the mouse i have is RGB light so its have low light now this is when AC power adaptor connected but if i unplug it with only battery connected when i press power button the mouse light appear then when i remove my finger from it light gone but no power @ all
so i tried this methods:
First i thought maybe there's some stuck charge in mobo so i removed whole things i mean whole...Last edited by AGmR; 11-28-2016, 01:52 PM.
