    DELL INSIPRON 14 No power blinking orange/white

    i have DELL INSIPRON 14 5410 2-IN-1 blinking orange and white when charger connected, i tried to find Boardview or schematics but cannot find. i opened the unit and the motherboard model number is 203071-1 Watchmen that i found written on motherboard. Where should i start because when i press power on, nothing happens. but i checked the main power rails voltages are enabled and the charging for battery LDO is 3.3 volts.

      In absence of schematics,always do basic things

      01.Observe the mb for corrosion/liquid spill etc under scope
      02.Check dc-in mosfets voltages and whether 19V reaches CLR
      03.Voltage on charging coil(should be 13V or similar approx as NVDC is being used very likely
      04.Check whether 5V/3V is generated or not?
      05.Check PS_ID is present or not.

          HP Elitebook 8460p battery led white and blinking orange
          by jorpec
          Hello everyone

          I have this Elitebook that wont turn on, only the battery led is white and blinking orange, does this even without battery.
          If this is a error code i couldn't find any info about it.
          Already tested with a another charger, measure the presence on 19v on the 19v rail, checked if there was capacitors in short-circuit

          Thanks...

          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...

          Dell XPS 13 9310 2 amber 4 white memory failure
          by Themi
          I have this laptop a dell XPS 13 9310
          Power on is ok, stuck at dell logo flashing 2 amber and 4 white (link dell service manual) 2,4 Memory or RAM (Random-Access Memory) failure​

          I believe this is the spec from using micron tool to decode marking

          Images of the ram


          I am thinking to replace but wondering if there is a possibility to test while in circuit to find the faulty module? I am doubting there is any reasonable test possible while in circuit as most ram ICs I have tested previously, I have done while off board / removed.

          Another...

          Board DAOP5HMB8F REV F
          Model OPSH
          No bios battery on board

          Power at cord 19.7, swapped cord 19.7V just to test, tested lid switch good

          Plugged in, battery in, charging port light on solid white, press power button, no fan spin, charging connector
          and power on light both blink white, not in sync, battery voltage 12.2 jumps to 13.0 for a second and then back and repeats.

          Not plugged in, battery in, press power button, no fan spin, power on only blinks white until battery removed, battery 12.7 - 12.1 for a second and then back and repeats....

          First one was not powering on when battery is connected the first n channel MOSFET was short and after changing the laptop started on power and battery and charging fine

          Second laptop has water damaged on ram ic after cleaning and changing the ic the laptop is working fine now

          But now I have power led continuously blinking 5 times in both the laptop even after shutdown and when it is powered on the led keeps blinking 5 times .both the laptop is charging and working on both battery...
