DELL N5010 power on but no display

Put DC supply amp.  144 - 160 ( means core not generate)


Open this laptop 

Check my basic points 

  

Check all coil impidence 🆗

 Check all coil voltages


   Vin section 👍✅


    3v, 5v  coil voltage 🆗


Ram voltage 👌


    3v , 5v conversion ✅


  1.8 v 👍


   Check 1.05 v pch coil (❌) not generate 

 

Open schamatic and trace 


1.05 v ic requirment check


    Power -5v ✅

  Enable- missing 


      This board design by wistron 


  I know,

              1.05v enble signal coming 

    Ram supply power good + 1.8v section power good 

     After mixed both power good

Known as ,

                     RUN POWER OK

         

RUN POWER OK  supply goes 1.05v enable signal

   

I check then found ram ic power good not generate

     

 👉 I see this path 3.3v pull up resistor(PR5004)


     One side voltage okk but other side no voltage 

 Checking purpose  shot this resister

   My board is on


After this, 

                 I chage  resister 0 ohm

  

My board is proper on & give display

HOW TO DELL MANUFACTURE MODE DISABLE


 turning Off the Manufacturing Mode for the System Board

Your replacement system board is shipped with the manufacturing mode turned on. After thesystem board is installed, you must turn off the manufacturing mode for your system to operatecorrectly. If the manufacturing mode is enabled, the system may not boot correctly. In addition,changes to BIOS and CMOS settings will not be retained, and you will not be able to flash update the BIOS.To turn off the manufacturing mode, perform the following steps:

 Turn on or restart your system.

 Press <F2> immediately after you see the following message:

<F2> = System Setup

 From the main System Setup screen, press <Alt><F> to turn off the manufacturing mode.

 Review the various System Setup options and change them as necessary to your preferred


system configuration.

For details on the various options, see "Using the System Setup Program" in your User’s

Guide.

 Press <Esc> to exit the System Setup program.

Save the changes you have made and exit the program when prompted to do so.


As the system reboots, verify that the manufacturing mode is disabled.If the manufacturing mode is still turned on, the following message appears at the top of the screen:Manufacturing Mode is Detected If this message appears, repeat steps 1 through 5 to disable the manufacturing mode and restore the System Setup options.
