      Have you taken any of the voltages on the connector marked 28 (OR 2B) shown on Picture 2 and can you report what they were.
      Willing to help but I'm no expert.

          Macbook pro A1278 820-2936 No light/turn on
          by Adogabriel100
          Hey! how are you guys? i wonder if you could help me with this macbook 820-2936 that does not turn on. (Doesn't have green/orange light).

          History:
          this macbook came for a short on C6990 that blows D6990 and R6990 on his way. i re-placed the componets and it work again.

          A month later comes back again and has the actual problem (no green/orange light and dont turn on)

          The macbook can turn on with only the battery connected but in fact, dosent charge.

          Voltajes:

          PP3V42_G3H = 3.3v
          PPBUS_G3H = 12.2V

          PS5 Slim EDM-040 Only turn on 1 Sec, Blue light then immediate off.
          by dionzarek
          Hello everyone, I am new to this PS5 troubleshooting, I need help on diagnosing the problem. My PS5 Slim board EDM-040 that beep and only shows blue light then immediately turn off.

          I've checked the PSU its normal 12V. I've checked all the capacitors its all good no shorts, but there are 2 caps shorted, I think its near the SSD. You can look at the image attachment.

          When tested it only shows 0.003 while other caps show 0.4 to 1. WHen in continuity mode those 2 caps goes beep/shorted.

          Any help to where should I check on or suggestion would be very appreciated....

          HP Omen only do not turn on, only flashes white light
          by ruletero
          Hi everyone

          Please help me with this laptop

          HP Omen 15-dc0003la , MB DAG3DBMB8D0 REV. D

          It doesn't turn on, when I connect the charger with battery orange light appears on power jack and without battery white light appear, it is fine I think

          But if I press power button, power led flashes white once, only that, not consumes anything power, not start, nothing more.

          Bios was programmed with a working version, no changes.

          Voltages

          +3vS5 = 3v when I connect charger, next goes to 0 (I think is fine)...

          Asus X453MA won't turn on and green led light blinking
          by jxrepman
          Hi there,

          I have this ASUS X453MA Laptop that's not turning on. When I plug in the charger, the green light just keeps on blinking and pressing the power button does nothing.

          I have checked the charger and it is giving 19+ V

          I have disconnected the battery and pressed power button for 30 seconds.

          I tried another RAM stick.

          Tried disconnecting the keyboard and touchpad.

          Tried disconnecting the HDD and the wifi adapter.

          The problem persists.

          Hope you could help me out on this one. Thank you.
