              Hi mate, when motherboard is short the following components go bad - Mosfets, Capacitors and sometime GPU (I dealt one such case with HP DV6 amd gpu). Well easiest way to test is set your multimeter to ohms range : First start testing all power fets which have 19 volts fed to their drains - simply put the probe between source to drain - then source to gate of mosfet (go online and read pin details of mosfets for better understanding - you can see some marking on the m/b which tells fet's pin 1 which is source and pin 4 is gate)

              Test only power Fet's and get reading (should not read .1 ohms +_) if yes then turn your attention towards that part and capacitors surrounding it.

              Good Luck

                How do you know it's shorted???
                I would start with mobo part number, so can look for the right schematics...

                    Doesn't have to be short...May be some regulator faulty...no?

                        9th Gen Dell Optiplex Micro PC motherboard repair: Short Circuit?
                        by Geeker007
                        Hi All, I have a 9th Gen Dell Optiplex micro PC motherboard which doesn't power on. When I connect the motherboard with power adapter, it goes into safe mode and turns off. So from info I have gathered online, it looks like there is a short circuit on the motherboard. So can you guys help me with figuring out the issue?

                        I am new to electronics repair, so my queries could be naive but I am ready to learn.

                        So I have a multimeter and a solder with me. But I can try to get a variable voltage power supply with a thermal camera as well. From what I seen online, best way is...

                        Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
                        by Bowline
                        My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

                        Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

                        My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
                        The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
                        I have tried multiple different Dell power adapters. My Dell...

                        DELL Nvidia GTX 750Ti Mosfet goes short after a few minutes
                        by aaronkatrini
                        Hi all,

                        I have recently picked up this Dell OEM Nvidia GTX 750Ti 2GB Video card. Its an old card I know but still wanted to get it working if possible. The problem is the following:

                        - Put the card in my testing motherboard and start running Heaven benchmark
                        - Benchmarks seems to run smoothly up until half way then the motherboard completely shuts off immediately
                        - Try to start it again and I get a slight move from the PSU fan - a clear short
                        - A little troubleshooting later I find one shorted Mosfet - Replace them both - short is gone
                        - Put the...

                        Dell E6430 19v line short
                        by usyusy
                        Dell E6430 19v line short,
                        (QAL80 LA-7781P)

                        19v rail, output side was showing a short (checked after removing CLR), a polar capacitor (PC1074-processor decoupling) in the core section was getting heat, when replaced that cap, the short gone, but when power on the machine, again that cap was heating (even had removed the processor already). so not understanding even no processor attached why this cap was getting shorted again and again

                        any guidance please.

                        Schematic:
