    Dell 2408: standby mode, orange light

    Hello Everyone,

    Last week, my Dell 2408 stopped to working. Now the only sign is turned orange led light. Pressing on it and any other buttons doesn't change anything. There isn't also any picture on the screen.
    It happened several times lately and solution was to unplug the power cable.
    Additionaly, when I turned the monitor on after e.g. whole night, there was one vertical line in the middle of screen, which disappered after 2-3 minutes.

    What I have alredy done:
    I changed the capacitors (8 in total) and KA431 on the middle PCB but without any results.
    I based on other topics here, however I couldn't find similar issue to this one.
    I hope it is not related with BGA chip soldering and still can be repaired.

    My equipment:
    Soldering station 936DH and simple multimeter

      Yesterday I heated up heatsink on the second motherboard and monitor turned on. After cooling it down, it came to the previous status.
      So unfortunately, BGA chip is somehow broken.

      Maybe I will follow the workaround described here: https://www.badcaps.net/forum/showpo...5&postcount=76

          Strange! Acer laptop not powering on but charging the battery (orange light on when charger and battery plugged in).
          by serious_electron
          Hello Everyone!

          I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died.          ...

          Dell Latitude 5420 / GDF40 LA-K491P REV 3.0 / Amber / Orange light when power button is pressed
          by zwect
          I have this Dell Latitude 5420 with ST: CMF62F3, board GDF40 LA-K491P REV 3.0 that does not power on, i already searched for some clues about this problem that happens on mine but no BIOS i downloaded and flashed did anything.
          Only when the power brick is connected, when pressing the power button an amber light lights up at the front and slight decreases its brightness, the RAM and the CPU seem to heat up if the laptop is left connected but nothing else, other than USB devices getting powered.
          Here is the original BIOS dump from the 25R256JVEN chip.

          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...

          LED TV Samsung The Frame 55 inch QE55LS03RAU Standby Light only
          by ChristianBr01
          Hello everyone,
          I got a Samsung The Frame 55 inch TV for free from uncle cause it is not turning on anymore. I am in the second year of training as an electrician so I have knowledge already but I am far away from to be a pro.
          The TV has Standby but ist not turning on. A Friend of mine owns a 50 inch Frame TV so I checked the One Connect Box and the One Connect Cable there. Both are good and working normally. I have opened the TV case and measured some voltages on the Board.
          What I already found is that the 12.8V are not an the connector to the main board connector to the power...

          macbook A2918, orange light off when shut off
          by mosfetratus
          When i fully shut off mac, orange light goes off and wont react to power button. I have difficult time resetting with combination "shift+control+option and power button", because it rarely works (reason unknown), when i manage to get orange light and then press power button macbook wont turn on and orange light goes off. When i hold combination with power button it turns on, and works fine if put it to sleep mode.

          Works with battery and charges, but when i shut off i get this problem.

          It had liquid spill. Board has no corrosion, keyboard is working, power button...
