    Acer v5-552 zri

    Repairing An Acer Board ZRI
    Problem : When Press power turn on light then off
    Culprit : Shorted VDDA_PWRGD line and solved by removing the PU1 and the unit power but no 1.2v
    Tried to replace the damaged part but when plugging the charger, amp goes to 3amp shorted board caused of the HI side mosfet shorted, I replaced it and same thing happen to the mosfet

          PU1 is Newly replaced, Problem solved but I dont know the real reason. After I replace new mosfet, It is not get short but the problem of the unit came back, When Power On it shut off if this circuit for 1.2v supply is in the circuit

              Acer Alienware Nitro 5 (GH51G LA-L181P Rev: 1C) & Dell Alienware M15 (GDP50 LA-k452P Rev:1) - Both Shorted PCH (SRKMA)!
              by reessi
              Hello:

              I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.


              I started on the ACER:

              Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
              All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.

              I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap...

              VGA MOSfet permanently shorted and loss of MOSfet pad
              by Nooy
              Hello everyone, I recently found this badcaps site and super Learn Electronics Repair youtube channel. And I wanted to learn how to troubleshoot power supplies and VGA cards and how to practice soldering, since I already have a properly defective piece of them. I am currently trying to solve two problems:

              I have a Gigabyte GV-RX460WF2OC-4GD type card. I managed to find the faulty MOSfet (AON6414A) on it, which I replaced. The card starts up, but after about half a minute, the MOSfet in the same position will be shorted again. Is it possible that the PWM controller driving the MOSfet...

              Acer Helios 300 N20C3- Dead Shorted mosfet blows
              by fallenapples
              Hey all

              Have the above laptop which is shorting out the power supply. 19v when plugged into the wall then when inserted into the laptop ir reads nothing untill you remove it from the wall and plug it in again.

              i found PQZ3 shorted so removed and confimed short gone.

              replaced PQZ3 and it shorted again?

              ive removed PQZ3 again and tested pads but theres no shorts there.

              Acer vx5-591G I removed Mosfet and it works without it?! could it cause problem?
              by ipn00tic
              Hello everybody,

              I'm learning alone at home (with you) of course.

              I have an Acer VX5-591G laptop that was given to me as scrap where I was training and diagnosing.

              The Laptop turns on and starts to boot for a few seconds but before displaying any image it short circuits the main 19V power supply and turns off.

              I managed to "repair" the laptop and it turns on and everything works, I even did game tests for the CPU and GPU and everything works but what I did was remove a Mosfet (PQ807) from the VCC_GT power supply.
              The VCC_GT power...

              ACER PEW71 LA-5894P CPU_B+ MOSFET NEED HEPL
              by jermac0711
              Brand : Acer
              MOBO: PEW71 LA-5894P
              Issue: initially no power. PQ73 mosfet is busted. (AO4466) . Unit has power now but PQ87 is heating up too much (observerd under thermal camera) causing to shut down the system. I tried to remove the removable CPU and the mosfet temperature went normal. I have a replacement CPU from same model but everytime there's a CPU, mosfet PQ87 temperature is rising rapidly.
              I hope you guys can shed some light. Thank you so much in advance.
