    Lite-ON made Dell SX280 PSU

    Just fixed/modded one of these. Filled with OST and L-Tec caps. No bulging but a lot of mediocre (in case of OST) and bad readings on some of the Ltec caps.

    A weird mix of Nichicon PW, HD, HM and UCC KZE was used to recap it. Mouser's stock was funny this time.

    The main switching MOSFET isnt very good and has a drain-source on resistance of almost two ohms. Swapping this for something more modern results in a cooler running supply. You can FEEL the difference! 2SK2654 was swapped for a Fairchild FQA8N100C.

    Fan was good, unlike the other version of the supply I'm used to (Hipro IIRC). The Lite-ON uses a 60x15mm fan, the other takes a skinny 60x10mm.

    The mobo is weird on this one...all Rubycon MCZ and Panasonic FL except for three Nichicon HNs. Why didn't they go all the way?

          Had me going with the thread title....was thinking to myself that I've never seen a bad DA-2 PSU (sx280 external, also used on the gx620usff). Made more sense after seeing the gx280 correction.

              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.

              Dell Latitude 5420 does not start (no post) need help to find the reason why
              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...

              Dell XPS One 2720 AIO Liteon PS-3261-9DA not starting up immediately
              by cheeky2
              I suspect the issue is with the power supply Liteon PS-3261-9DA as apparently they are notorious for issues with them. Has anyone else had similar issues where the PC tries to boot up a few times before finally booting up. Now I have opened up the PSU which shows no signs of any capacitors failing. I did remove one capacitor that looked to have an issue however with my peak meter it showed it was within the limits with good very low esr values which was somewhat disappointing!
              I am going to put a Meter leads across the outputs to see how stable they are when it occurs to see what they are...

              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.

              Dell Inspiron 5590 Board 18778-1 no charging, charging not possible
              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...
