    Okay, ordered it from China, will arrive until the 18th at the soonest. Will be a long wait. Will let you know when it's here.

      I replaced the part but no change. Pretty sure I soldered it properly too.

      I still don't have some of the vital signs we talked about. PCH is not being taken out of reset, RSMRST isn't going high. DNBSWON does not go down when I push power.

      I will go through the check list again tomorrow but in the meantime do you have any other ideas of what I could check?

      One thing I did discover is that the hall effect sensor looks to be shorted, when i put a magnet on it the state of the output will not change. I took it out of circuit and I'd like to hard wire it to be in the state it's in whenever the cover is open. Should it be high or low for it to be as if the laptop is open?

        The general rule with the lid switch signal is that an active state means the switch is being activated by the magnet (i.e. the lid is closed). Since the signal is named LID_EC# (with a '#'), the active state is 0 volts. Therefore, lid closed = 0 volts, and lid open = 3.3 volts.

        Worth checking.

        I'll have to think about other possibilities. After I've had sleep. heh

          Hello, any help will be apprecited!
          • Model: Dell G15 5511
          • MB: LA-K452P
          • Issue: Won't turn on at all, no leds, no keyboard light, no fan spin, nothing happens when pressing power button. NOTHING.
          • Customer reported it was turned off and left plugged in during the night and thats it...
          • No signs of liquid damage or burned components.

          I have checked so far:

          JS47A/JS57A/JS77A NM-E531 onboard ram disable
          by rex98
          hi i have this laptop IdeaPad 3 15ABA7 this is the boardview https://www.badcaps.net/forum/troubl...90#post3740490

          nm-e531 i tried all kinds of bios editing and it doesn't work. it doesn't have schematic but it has boardview with board ID details in it.
          maybe you could help me how to shift these resistors to disable its onboard ram.

          this is is the presents and not presents...

          Epson EB-U42 projector / Caps with 0.7 ohms ?!
          by narf
          hi all,

          first of all: i'm a (motivated) newbie, so please forgive me any stupid question i may or may not ask

          i'm currently repairing a projector: Epson EB-U42 that doesn't start (no lights, nothing).

          what i've found so far:
          - the PSU does its job and supplies 12V to the mainboard via the connector.
          - shortly thereafter, there is a mosfet (TS420-600B) where i can test 12V on the one side (in the data sheet this side is called Anode), Gate 0V, Kathode shorted to ground
          - not far away, there's the first cap with a resistance of 0.7 ohms....

          820-01521-A (MacBook Air A1932 2019) stuck on 5V
          by mferna14
          Hi all dear friend., today I am working on 820-01521-A logic board (MacBook Air A1932 2019) stuck on 5V .19 milliamps. The history of this logic board was liquid spill on major components. First gave a good cleanup & both CD3215C00Z were getting very hot, so I replaced both. Now on the 12V coil, there is only 5v present & 3.3V is perfect. In some area like PPVIN_G3H_P3V3G3HRTC , PPBUS_G3H_TPAD etc., 12V is perfect. On the 5v coil .2 volts only. I checked the enable signal on the regulator chip, enable is NOT present. The logic board is very clean, I do not see any signs of spill anymore....

          Dell 2007WFP resistors under white silicon blog
          by BustinCaps
          My beloved 2007WFP just died on me. It has a green blinking light that just cycles through various display numbers. For a while I noticed it would blink slightly like the refresh rate was off. Nothing I have done has been successful in turning it on. So I took it apart and looked at the USB board since many people have had problems with the resistors under the silicon blob. I looked at the various other boards for the obvious signs such as blown caps, bad fuses, burn marks etc. Nothing looked obvious. I also checked most of the caps with an ESR meter and they checked out good.
