    Gateway NE56R10U CPU VCORE missing

    Shematics:

    This laptop originally had a shorted cap near PQ31 and also PQ6 and PQ7 were short. I removed the cap and replaced the FETs and now the laptop will turn on briefly.

    When you hit the power button it comes on for 5 seconds then shuts off and repeats 5 times.

    I measured for CPU_CORE on PL19 and PL20 and it never comes up.

    The schematics are kind of messed up on the page that I need (page 54) and I am also a noob, so I am finding it difficult to troubleshoot why the CPU_CORE voltage is not present. Can someone look at page 54 and interpret that mess for me?

      Check the datasheet:


      What about PL21?

          CPU vcore missing in HP workstation Z2 Mini 4G
          by Francisco.s
          Hi, have a HP workstation Z2 Mini 4G for repair with CPU vcore missing.

          The resistance at the output of CPU vcore coils, is less than one ohm so I think CPU could be damaged, but no mosfet are damaged.
          It mounts an i7 8th gen, and have only i5 7th gen for test, but I think it is not compatible.

          Without CPU in the socket there is no short, but there is no vcore voltag, and it emits a beep like no detecting ram.

          The controller chip for cpu vcore is a MP2949A, and has no enable voltage at pin 37.

          I wonder which circuit generates this enable...

          RTX 2080 ti (Zotac - triple fan) - No video output / Vcore / Vmem missing
          by T4H
          Hi,
          I have an RTX 2080 ti (Zotac - triple fan) with no video output.
          So far I have measured the following:
          • PS_FBVDD_PH3_SW = 40 ohm to ground (Micron ICs) - Memory should be fine right?
          • 12V power rail present
          • 3.3V power rail present
          • 5V power rail present
          • 1.8V power rail present
          • Vcore power rail missing --> PS_NVVDD_VREF is present. (from uP9512P / U812)
          • Vmem power rail missing --> Not there because Vcore power rail is missing.

          Any idea? I have already tried to flash the BIOS chip (backup got created) - sadly no changes.

          MSI Z390-A PRO missing VCORE voltages
          by karlp028
          I've got an MSI Z390-A Pro motherboard that starts up fine, but it's missing the VCORE (and VGT) voltages. All of the other voltages are present (e.g. VCCSA, VCCIO) and I know the CPU (i7-9700k) is good. Now, the original PWM controller (UP9521P) had an internal short and I replaced it with a new one. All of the enable signals look good. The problem seems to be the PWM signals going to the MOSFET drivers. I checked them with an oscilloscope and they are all flat 1.5V with no pulses. I don't know why this would be and I'm not sure where to look next.

          Z170 Pro Gaming missing Vcore after cleaning
          by brusli009
          I bought it used and was filled with dust, but was working fine, took the heatsinks off and gave it a quick clean with ipa and a soft brush.
          The next day it starts but the vcore is missing, also the qled dont light up, from what ive seen on the boardview (posted on the forum) i think im missing the vcore enable, but not sure. Also if the 8pin cpu is removed when the board is started,it dosent do anything, feels like the board dosent know that its connected.
          Maybe someone has some ideeas or something.

          HP 17-cn0234ng - RAM and VCORE voltage missing
          by chbalnuweit
          Hi all,

          I got an HP 17-cn0234ng and I am hitting a wall diagnosing it.

          When I first got it, it wouldnt turn on at all and no lights were active.

          I found a shorted capacitor on the 3.3V powerrail near the lid sensor. Once I removed the shorted capacitor, the power and charging light on the DC connector started working and the Laptop reacted to the powerbutton.

          When I press the powerbutton, current consumption goes up to about 50mA and just stays there. Chipset and 3.3V regulator getting a bit warm under thermal camera, but not really noticeable...
