    HI sir!! please a1398 coil short

    Hi Sir Thank you!

    I want to get help.
    I was working on a macbook a1398 repair.
    The cause is that it turns off during use and the cooler turns very quickly when booted.
    It doesn't turn on, but it keeps turning off like this.

    When I disassembled the main board and checked it with a tester, the other coils are ok
    Can you help me?

    I'm really grateful
    Thanks anyway!!

              Dell E5470 LA-C631p - Short removed now turns on but no post/display
              by retrorepair2
              Got a really frustrating issue here, got a Dell laptop as above which initially had a short on the +POWER_SRC rail, discovered a short cap in a bank of 3 near PU801. Removed and verified the short was gone, it was and the laptop powered on, tried to load windows but just kept rebooting. Sometimes didn't post. Battery was charging.

              Stripped it back down and replaced the cap (assumed looking at the LA-632p schematic it's a 10U cap, no boardview so who really knows). Now the board doesn't charge the battery and while it powers on with a brief spin of the fans, there's no display on the...

              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...

              A1398 15” 2013 short when screen plugged in
              by bogosort
              Hello,

              I have a MacBook Pro 15” A1398 2013 that has no backlight, but I see an image when putting light through the logo. I noticed that when the screen is plugged in, I get a 300 ohms short (see image).

              When unplugged, the short is gone.

              Any idea?

              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...

              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...
