    HP EPK50 LA-G07EP short on +3VALWP and +1.0V_PRIMP

    Hello,

    Working on a board HP EPK50 LA-G07EP. Owner tried to replace LCD display without disconnecting battery. Afterwards, the notebook turns on for a few seconds and shuts off.
    Mainrail looks fine, battery charges. I have +5VALWP, but that's it.
    I measure short to ground (0.03Ohms) on +3VALWP and +1.0V_PRIMP.

    Injecting 1v at 3A on PL1001 and PL302 only slightly warms up the cpu after several minutes.

    Short on +3VLP coupled with short on +1.0V rail= Shorted SOC.

      I was afraid for that, so this one is unrepairable

        Yes, unless you want to replace the SOC.

          Extreme High Current & Low Voltage Short Killer ??
          by DynaxSC
          Hi Folks

          I'm looking for a extreme high current short killer solution for a reasonable cost.

          I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
          After taking off the socket, the shorts dissappear again.
          The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...

          Acer Nitro 5 3valwp short 1ohm
          by Thomas8607
          Hi all!

          I have an acer nitro 5 notebook. The 1,05v, 1,8v and 3valwp were short.
          I injected 3v on 3v rail and the pch was hot,i desoldered it.
          The 1,8 and 1,05v are ok now, but the 3v still shorted.

          The 3v to ground resistance is 1ohm (not zero).

          Where do i find the fail?
          I have schematic and boardview too.


          Thanks!...

          MacBook Pro 14" A2442 Short on PPBUS_AON but no short present when injecting voltage!
          by Stephen
          I check PPBUS_AON and there is a short present on the line, the computer shows a short when testing for short to ground, so when I inject voltage into the line, I get 0AMPS so no short is showing up. I have replaced a blown cap on this board that exploded and tested for the short and it is now removed. Any suggestions? I tested voltage at the line when the fuses are connected and I am getting 1.2 Volts at the line.

          HP Victus 15-fb dag3pamb8d0 Short on VCORE – How to Confirm CPU Fault?
          by adelfr2009
          I have a laptop HP Victus 15-fb with motherboard DAG3PRMB8D0, CPU Ryzen 7535HS, and GPU RTX 2050. The laptop has a power issue: it does not turn on at all, and there is no light on the DC jack.
          After inspection, I found that an NMOS near the charger input had a short. I replaced it, but the short remained on the 19V line. I checked the charging circuit and it was fine, but the short appears after the current sense resistor near the charger. The charger does not pass current when connected, so I inject 3V–4V after the sense resistor. No component gets hot, except the CPU which becomes...

          Help me find the short circuit on this WORKING Nvidia GTX1650
          by aaronkatrini
          Hi all,

          Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.

          Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...
