Dell Vostro 3560 no power :'(

[AGmR]

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 just mobo with power button + cmos battery also then
pressed power button for +30 secs

second i flashed the right bio hard way with spi programmer i did it before
many times when the mobo was worked before for testing purposes


so still same problem i think now its maybe short in circuit or smd caps or
mosfet dead or something i dnno :'(

so im not pro with hardware components but i need someone guide me what to do
with multimeter to test figure out whats components dead to replace instead of
replace the whole mobo cuz i cant do it and even send it to technical repair
shop cuz it cost here so much $$ yes i mean it

so this is my schematic >>
