    Dell 510m Laptop just squeels

    Hi everyone.

    I am a new member here but have often referenced posts that have helped me repair many things so thanks to you all for sharing your skills and knowledge on this excellent website.
    I really don't know if my current problem is related to bad caps or not as it is a Dell 510m laptop mobo with mostly SMT stuff.
    I have two of these that when power is applied and the 'On' button pressed the green power light blinks briefly and it make a low volume high pitched squealing type noise and shuts off in a few seconds.
    This can only be heard when the mobo is bare-bones and I am familiar with testing this way. I am using good ram, CPU etc and the PSU is fine and Dell branded.
    It is defiantly a board fault and I just wondered if anyone had any ideas before I scrap them.
    I cannot locate where the noise is coming from, it's quite deceptive on the ears!
    Thanks in advance for any advice.

    Phill.

      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 Inspiron 14-5448 - fan turns off and mobo keeps running
      by Felipe_Serra_83
      Hi, everyone. First post of an actual repair. I'm a technician but a complete newbie with laptops.

      So I got this Dell Inspiron to play with.

      No charger, so I connected to my bench PSU.

      The laptop also didn't include: hard disk (I added one of my own for testing, see below) and wireless PCB (but I doubt this could have anything to do with this particular failure).


      ------What it did (and didn't do)------

      1) I turned it on and it powered on. Powered down in 2 seconds by itself.

      2) Removed RAM, changed slot. Same...

      Dell G3 17 3779 - no display after mobo replacement
      by mrsith
      Hi guys,

      I have a friend's Dell 3779 that came to me with severely shorted mobo. Did not manage to isolate the cause, most likely that was a bga shorted. Went for a replacement motherboard. Got one from China, apparently it's been tested prior to shipping. The mobo starts up normally but I am getting no display whatsoever.

      Tried using external monitor, but being blind I am not sure if laptops goes as far as booting to Windows, a d without it I cannot get hdmi to work. Can't see boot menu options to make sure it boots to Windows. Went ahead and did a blind bios update,...

      by F R 2568
      Hello all,

      this is my first post, so if I make mistakes please do not hesitate to point them out, thank you in advance.

      I got a Dell Latitude 5420 (Service Tag: 7RFM6D3, Motherboard: GDF40 LA-491P Rev.: 2.0 (A01)) which does not start and I want to repair it. These are the symptoms:

      If the laptop is only connected to the AC adapter (battery removed):

      When I press the power button, the keyboard backlight and the display backlight are turning on. Caps key light is lightning, but key does not respond to pressing it.

      The power/battery...

      Looking for Dell Latitude 5520 / 5530 / 5540 RJ45 network connector replacement
      by diamon
      I have a Dell Latitude 5530 with a damaged RJ45 network connector. See the attached pictures.

      Have already searched on Farnell / Aliexpress / Ebay and had contact with several suppliers on Aliexpress and Ebay, but they cannot deliver this connector.
      Is there someone inside the EU, who has these connector(s) or perhaps defective motherboard(s) for these laptop models I have mentioned in the topic title.
