    Dell n5010 dg15-09909-1 mb

    No apparent shorting on the mb. no 3v/5v present. I replaced PU4601(51125) and replaced sio still same. Pin23 of 51125 is not giving 3v powergood signal. I injected 3v from psulab , no componenet heated up.

    On ething i have noticed is that resistance connected to pin23 of 51125 shows 2.2k whwereas it should so 97k approx. If vi remove the ic resistance rating becomes 97.

    I have tried putting up 51125 from working mobo and after soldering the ic resistance shows 97k. the moment i give power to mobo resistance shows 2.2k.

    What can be wrong??

          Thanks for your reply razu. The problem is i dont have 3v/5v on this mobo. I have tried changing the following ic's
          01. 51125
          02. 51116
          03 charging ic
          04. Sio

          Still no 3v/5v. I have checked all the mosfets-nothing abnormal and my power board is tested ok.

          Checked resistors near all ic's and seems to match with schematics.

          Wondering why 3v/5v power ok signal is not enabled on 51125.

          Can anubody guide me the preconditions to enable 3v/5v pok signal on 51125??

              Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
              by Bowline
              My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

              Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

              My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
              The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
              I have tried multiple different Dell power adapters. My Dell...

              by minaedward
              Hi all
              I have a dell n5010 that shows black screen after the dell logo and freezes
              But when I remove the keyboard it works fine and boot the windows
              The keyboard is working as I can press F1 and F2 and inter the bios settings and change it
              But after the dell logo it causes the laptop to freeze
              Any ideas why ?

              GTX 1080 TI Gigabyte Aorus low resistance on vmem
              by cind12
              Hi guys, i was wondering, i've got 9Ohms on Vmem, one of the mosfet was shortet to ground, so i've desoldered hi and low mosfets nad still low res, then i removed all of the memory chips, and the resistance is still low, so did you had maybe a card with that low res on memories, and the card was working fine ?
              Removed the U1866Q and still without result, i dont have thermal cam so can't see where is hot spot when incjeting voltage.
              The resistance on core is ok 0.1Ohm ((Power 0.8V when on)
              Resistance on 12V 4K ohms (Power present when on)
              Resistance on 12V PEX 4K ohms...

              Dell Pro 13 Plus PB13250 Bios Unlock
              by Akhlz001
              Hi,

              Could someone help trying to unlock this BIOS, seems that Dell have changed the layout of new Dell Pro 8FC8 bioses from checking HXD - 4000 bits do not need changing, only 2000. However after FF the section starting from '01000' upto 2000 bits and then soldering the chip back it seems that the microchip on the motherboard is recovering the bios back to original settings after first boot. Has anyone found a way to crack this extra layer of security Dell have implemented? Seems both HP and Dell have upped bios security to match Lenovo by implementing extra measures on a separate...

              by master3112
              I would like to share my experience about charging issues with Dell power supplies with the tech community. I am working on a Dell Inspiron 5590, Mainboard 18778-1 with charging problems. The device can be switched on and works so far, only the message appears at startup:

              Alert! The AC power adapter wattage and Type cannot be determined. The battery may not change. The System will adjust the performace to match the power available.

              The power supply unit is not recognized in the Bios and the charging process is set to "idle". I use original Dell battery, type...
