    Troubleshooting Dell P69G motherboard not turning on

    Hi all,

    Have an issue with a P69G Dell motherboard.

    Came in because wasn't turning on. When it comes in the shop, as soon as you plug the charger in, the light of the adapter goes off immediately and when you take it off from dc in, light comes back again so board was shorted.

    Injecting 5V on DC in FPC on board, and this chip (Z22620IA?) circled was getting very hot (unfortunately couldn't find schematics nor boardview so don't know what is it and how does it works exactly).
    Took off this ic, and now light on adapter stays once plugged in but still no boot on the computer.

    The small 2 pads connected to the coil just next to it beeps in diode mode (don't know if it's normal because low resistance or the line is shorted).

    What do you think?

    Thanks for your inputs

              You guys think i should just replace it?
              What about those 2 pins beeping in continuity mode ("LX line")? Low resistance? Shorted line?
              What would you try after that?
              Thanks

                  Dell Latitude 5350 Ultra 7 Motherboard
                  by Julian Bailey
                  Hi

                  I have a Dell Latitude 5350 Ultra 7 Motherboard I am trying to repair that has a blown chip.

                  The chip is marked as eHOLH similar to the one I have pictured.

                  Any ideas what it does and what the pin outs are as 3 tracks have gone and need to find out what / where they went / did etc.

                  Dell PN of the motherboard is 08DCGW.




                  Below is the area I am trying to repair:



                  Does anyone have a picture of this motherboard in this area they could take and upload?

                  Cheers...

                  When I press the power button, the keyboard backlight and the display backlight are turning on. Caps key light is lightning, but key does not respond to pressing it.

                  troubleshooting microsoft surface pro 4 no power no led charge light
                  by ipatch
                  hello, �� i have been sitting on some microsoft surface pro 4 tablets for a while now. i was originally tasked with replacing the battery in one of the tablets, and ended breaking the screen and logic board in the process. decided to buy another tablet with the same specs. got that screen off successfully of the second tablet. the logic board appeared good, but i guess i shorted something out in the installation process of the logic which i've read is a common issue if there is no barrier between the logic board and battery pins. all that said, i ate costs of the repair and have...

                  Some help with troubleshooting a HP ProDesk 400 G2.5 SFF motherboard please
                  by Bob_Crachet
                  I am experiencing the following symptoms:

                  With the device fully assembled when I press the power button, nothing happens at all.

                  I pulled the power supply from the computer and stuck a paperclip into pins 16 and 17 on the connector causing the power supply to turn on and the fans to start spinning. All of the voltages checked out ok.

                  With the power supply outside of the case, I plugged it back into the motherboard and tested it again. No change. PC did not turn on.

                  I put my multimeter in continuity mode and put the black probe on one...
