    ASUS G513Q short on 1.8 and 0.75v rail

    Hi all,

    I have this laptop that initially had a short on VBAT

    I found that the short was coming from U60600, a DC/DC converter responsible for 1.8v. There was also a shorted cap on pin 13, the LDO for the chip.

    Removing these has cleared the short on VBAT. But 1.8v and 0.75v rail read 0.1 OHMS.

    I have read another article here that said that this typically indicates a failed cpu.

    Is there any way to confirm? I was borrowing a thermal cam and now don't have one to see what heats up on that rail. I feel like I may be wasting my time...

    Schematic attached, see page 18.

    Thanks guys.

      When injecting voltage on the 1.8v rail, the very edge of the CPU evaporates alcohol immediately. I think this is game over. Can anyone confirm?

      Thanks!

          Have not checked the schematics but is this rail linked to the cpu / pch?

              Yes, it is linked to the CPU.

              I appreciate your reply

                  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...

                  Xbox One S - 12V Rail Short - Q9F1 Keeps Blowing
                  by grimacelord
                  Hello,

                  Have an Xbox One S here that has a short on the 12V power rail. There is no power, beep, or partial fan spin when connecting power cable.

                  After diagnosing with thermal camera, Q9F1 MOSFET (NTTFS4C50N) is getting hot. When I remove this MOSFET, the short on the 12V rail disappears.

                  I first replaced Q9F1 with one from a donor board and then partially reassembled the Xbox to test. When I plugged the power cord in, I got a partial fan spin and I thought I had fixed it, but unfortunately, the Xbox still did not power on. So I then disassembled the Xbox...

                  Asus Geforce Cerberus GTX1050TI-O4G-DIS short circuit in the FBVDDQ rail
                  by nagkiller
                  Hello everyone!

                  This grafic card came for repair, but when I connected it to the motherboard, the board would not start (short circuit in the 12V rail).

                  After removing some PLs to isolate the short in the 12V rail, I got to PML1/PML2, according to the BoardView reference.

                  Even injecting a voltage of 1V0 and a current of 3A in the FBVDDQ rail, for example, the voltage drops to 0V20 and none of the components heat up.

                  The attached boardview file is very similar to this grafic card, which I am basing the repair on.

                  I would like some...

                  Acer AN515-55-528T FH52M LA-J891P - Short ciruit after PQW1 MOSFET on +1.35VSDGPU rail.
                  by joshAU
                  Hi all.
                  This notebook was showing no signs of life.

                  I removed the FH52M LA-J891P mainboard and found that there was 19V at the DC jack.
                  However there was zero volts on the two PRB2 and PRB46 resistors immediately after the two polarity protection MOSFETs (PQB11 & PQB12).

                  If I remove the PQW1 MOSFET, the 19V rail starts working, and I can turn on the unit - at least I get the fans, and the power light comes on, when I simulate the power button being pressed. No display.

                  I tried replacing the MOSFET with a new one, but again no voltage on the...

                  Gaming laptop Clevo NH79EP with short on 5VS-rail
                  by techrepairheide
                  Hello,

                  first of all I want to apologize for my bad English, but I try to give my best.

                  Customer brought me a laptop, which is charging the battery (when the dc-jack is connected) but don't power up when the power-button was pressed down. Only the white LED lights up, and you can hear a short noise in same interval when power-button was pressed and hold for longer timer. The customer changed already battery and dc-power-adapter.

                  For this laptop the correct shematic is the service manual "Clevo NH50ER NH57ER NH50EPS NH57EPS - 6-71-NH5S0-D02 Schematic"....
