    What is the exact resistance on that coil?? It is supposed to be low. Why dont you remove the coil and see which side is shorted?

        too low.. it is probably a shorted smd cap.. inject 1v 1A and hope something heats up..

            I see a fet missing in your pic. have you soldered a new one there?? 0.8Ohms may not be low if that coil is part of vcore circuit as cpu is onboard. Btw, which side of the coil is shorted?? Remove all caps near the coil and check them out of circuit.

              i already tried changging the mosfet and checking all the coils showing some of the coils is shorted

                those readings are solid short circuit.. try to remove all the coils to isolate the circuit.. then try to test it again where is the short coming from.. happy hunting!!!

                  This is diode mode, not resistance mode. Also attach pictures directly to your post with a better resolution (and without random shady links).

                    Re: Da0zqfmb6f0 rev f shorted

                    did you find the short circuit? he is using diode mode and testing the circuit with red probe
                    ground and black probe for poking. did you remove all the coils?

                      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...

                      Hey Forum,

                      I have a dead Acer Laptop from a friend. Find out that its a Mobo fault because Screen is working on other mobo and there are 19V on Power Jack that are going over the two Mosfets into the Mobo. So its actually charging too but no matter what i Do the leds wont come on. So i went over to the 5v and 3v Section and there is nothing at both. The 5v Rail is okay so no short but at the 3v Rail theres a short at PJ401 and on both sides from the Coil PL402 but on the capacitors there is no short. So i found a 19V 3.42Amps Charger (it works) plugged it into the Mobo and the Step...

                      HP elitebook 8470p, no 3V on coil in step down section
                      by usyusy
                      HP elitebook 8470p is not powered on/dead,

                      in step down section, 5v is ok on 5v coil (L6150)
                      but no 3v on the coil (L6100)

                      3v coil (L6100) gives beep from ground as well as a big black capacitor (C6100-150UF_6.3V) while putting both probes on it

                      any guidance please....

                      by Yanleb
                      Hi every one. I just want to share the successful repair of my shorted Panasonic TNPA4782AB SC board.

                      I don't usually do it but so many parts were shorted that I decided to buy the ShopJimmy repair kit instead of sourcing each components individually. Here is the list of components the kit contained, with a remark indicating if I needed that part or not :

                      D608, good
                      D618 RF101L4S, good (See warning 1 below)
                      D619 RF101L4S, good (See warning 1 below)
                      D865 RF101L4S, shorted (See warning 1 below)

                      Acer Nitro 5 LA-L181p power LED turns on by 5 secs (Short on PCH rail?)
                      by Victor Moreira Silva
                      Hello everyone,

                      I'm trying to repair my old Acer Nitro 5 (AN517-54-55T5). I've already bought a new laptop, so this is more of a learning project. For the experience, with no high expectations of success.

                      Well, my decice specs are the following:

                      Model: Acer Nitro 5 AN517-54-55T5
                      CPU: Intel Core i5-11400H
                      GPU: NVIDIA GeForce GTX 1650
                      Motherboard: GH51G LA-L181P Rev:1c

                      The symptom:
                      When pressing the power button, the power LED lights up for about 5 seconds and then turns off. Initially, the issue was intermittent: sometimes...
