    Asus UX51VZ Zenbook U500V

    Hello,

    I need some help in figuring out if the short i have on this board it's a short to general ground plane or it's a defective component somewhere in the positive current distribution.

    I have a short to ground from the choke near the charger input, a short to ground from the chokes for 5V and 3.3V, a short to ground near the BIOS chip, a short to ground from a choke near the battery connector.

    I attached some images with areas and an arrow that points the direction of the short. The RT 8239B present on this M/B it's shot, but i do not have a short to ground in that area, all the shorts seem to be on the Vin feed. If i connect the charger the path immediately following the charger plug get's hot and it blows the first FET as marked on the picture.

    Being unable to find a schematic for this board, things are somewhat confusing. I managed to find the UX31 schematic but it's not entirely correct, of course, for my case....

      Hello, I have already almost this same issue.
      Seems every 3,3V or 5V is on short, I removed some MOSFETs like you and replace them but with no lucky.
      Everytime I put voltage at shorted point some times I only get heat at Southbridge chip.
      I have the boardview but I'm confused, could anyone help me?

                  450watt power supply 5v, 3.3v short to ground wire,in output rail ,connectors
                  by playit
                  hello everyone , working zebronics power suply 450 watts , 5v ,3.3v givin short to ground black wire, also in circuit at output, resistor was charred but shows right values , after removing resistors 39ohms, 51 ohms, there was no short , no continuity beeps with ground , but after replacing new resistors (now i am not switching it on) ,again short still exists . when i put bigger ohm resistor like 100k ohm , no short beeping sound comes , lower ohm resistor gives continuity beeps ,other big ones donest , as its a working psu , i am confused what to remove now or how to go further now .

                  Asus ZenBook 13 UX333F External Short - Fast Battery Drain - Need Help
                  by jkucukov
                  I'm trying to see if someone could help me with my Asus Zenbook 13 UX 333F with given symptoms that I've experience during a recent external short.

                  During last laptop charge, as I was moving the DC power supply, I caused the two leads (+ -) to touch. After that event the laptop stopped charging and pulling amps form the power supply. The only way the laptop will come on is with the power supply connected and the battery having some charge to it, battery drains immediately after short operation (it gets to Windows log in screen before it shuts off). The laptop would power on, show...

                  820-00840 / No boot / PP3V3_G3H Short to ground
                  by MisterAIL
                  Hello everyone,

                  Firstly sorry for my english, french guy inside.

                  I brought a macbook pro A1708 - 820-00840 logic board, wasn't powering on.
                  History is a day, nothing happened when opening the laptop.

                  Nothing special inside, no corrosion, no liquid damage, never opened.

                  First, with the logicboard alone on the desk, mesures are :
                  5v017 and 0.000 amp. nothing else.
                  Finding a short on the PP3V3_G3H_VR, but not on the PP3V3_G3H (0.540 on diode mode), PPDCIN_G3H_CHGR_R present (5,1 volts) PPVIN_G3H_P3V3G3H around 4.1 volts. PM_EN_P3V3_G3H...

                  made house call.

                  disconnected from mainboard.
                  determined PSU ok BL ok.
                  suspect mainboard.
                  disconnecting tcon has no change on operation.
                  markings on mainboard:

                  BN97-06531P 0151
