💥case study laptop dell 3521 la-9104p problem dead. 💥return from other repair service centre. 💥 plug dc reading is 0.000. Open laptop check all coil value okay cpu coil is 0.001 means have chance. 💥 observe the motherboard find the first mosfet was miss i check gate voltage there is 19v thats not good. Put jumper on first mosfet and 2 mosfet and put ram ic in wrong position. I correct it. 💥now my reeding is 0.006 trigger motherboard goes 0.0012 come back. Now i change 3v & 5v output cap with 330. Before trigger board. 💥 I check 3v & 5v valve now my 5v line short. give 2.4 voltage on it and check heat my ram ic was heat i check ram ic vcc its low value removed ic shorting gone. 💥 Now i replaced ic and value good plug dc reeding 0.007 press power button reeding goes to 0.017 then back again. 💥 I don’t have 3v 5v on coil it’s always voltage then I check check entrip pins no voltage. For testing I remove PQ206 my 3v 5v ready dc reeding is 0.0011 press power button reeding same is .17 and back. Now i trace back EC_ON i don’t have EC_ON voltage. 💥 I note when i press power button and reed goes to 0.0017 that time is i have EC_On & when its back my EC_on 0v. I think i/o problem put new i/o program its with RT809F. 💥 After program i/o same condition. I was too confuse then i thought let’s fix 19v section i remove jumper put mosfet. and check both gate voltage there id 19v on gate its P channel mosfet i trace back gate there is one game changer PQ114 there is no ACIN on its gate. 💥Now i trace ACIN and i check charger ic requirements dc in goes in side but ic nothing come out then ic carefully the charger ic is wrong number 🤯 before change ic i put 3v coms on ACIN my 1st 2nd mosfet gate voltage is 8v that’s good 😌 put new charger ic. 💥Now my dc reeding is 0.005 now i have EC_On 3v and 3v and 5v always. Why i don’t have because my ACIN is goes in side of i/o then i/o put out EC_on 💥 i press power button reed goes 0.137 all voltage okay but no cpu core voltage check core ic requirements all okay but no core voltage now i check uz1 and qc3 one side i have 1.5v voltage other no voltage check both gate 0v there B+_Bias track is miss and RZ18 also mis. 💥 Now i arrange RZ18 its 470k it’s very hard to find. Makes same track and now my voltage was pass and also have core voltage and i also flash bios. 💥 Now press power button reading goes to 0.600 , 500, 400 and 3 time restart. dell 3521 u don’t have display without screen older Engineer also damage screen and cable also. 💥💥💥Its very hard and challenging form to repair this kind of motherboard. It’s possible because of I’m AFS Solution student. 💥💥Thanks to MD. Rafi make us that level engineer. Thanks to give that confidence cpu jinda reha to ess ki amma ki kasam ye display deyga💥💥💥💥
