    880M GTX that has a short

    Hi, I have a 880M GTX that has a short. I removed the coils from the VRM side and the short still present so its from the GPU side?

    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.

    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...

    Lenovo Thinkpad P72 EP720 NM-B723 MB - Power disabled within 2 seconds after plugging the charger
    by Mita99
    Hi,

    Try to repair a Thinkpad P72 EP720 NM-B723 MB with I7-8850H processor and N18E-Q1-KB-A1 (P3200) GPU with 6GB memory. Unfortunately there is noinfo what happened to the laptop. I got it disassembled with parts missing, like keyboard, battery.

    Unfortunately I have no schematic available for me (requested in the sub porum) but got the boardview file.

    Symptom: after connecting to the charger the power led light up for one-two second and switch off. After a couple secons the power led light up for half a second and switch off. No battery, no IO board, no...

    HP Omen 15 - Short on GPU side but only draw <2W
    by tienlk19
    Hi there,
    I have this HP Omen 15 (GTX 1050) with a shorted GPU. GPU coil resistance 0.1 ohms in continuity mode with 0.001V drop in diode mode.
    I then desoldered the coil and confirmed the short is on GPU side. (Without the GPU coil, the laptop power led lights up when plugged in)
    I injected 1V to find the short and to my surprise, the board only consumed 1.8Amps (My power supply can provide 10A max) and nothing got hot.
    At this point, I am lost. There should be a short somewhere on GPU side but how can it only draw less than 2W?

    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...
