    Dell latitude 10-st2 not charging and not powering

    Greetings....
    The above tablet is not turning on nor charging. I noticed a diode close to the battery connector has blown. The number on the 8-legs diode is "3EEHG"

    I'm having problem identifying this part for replacement.

    Please help

        There is schematic for this, but only on paid sites like vinafix, I couldn't find anything free.
        I don't provide help for people using CH341A and a clip.

          See attached. Mystery solved. Do not ask me to explain the trail that got us here but it makes perfect sense.

          This is an ESD protection array for the HDMI section that Dell / Wistron likes to use.

          Datasheet is attached. You should be ok to find these on Aliexpress and also possible to replace with others.

          The real p/n is on the TOP LINE which was damaged and is '118'.

          The 2nd line that is visible = datecode for the actual part.

          Here is one store of many that can supply this part:

                Dell Latitude 7430 - LA-L581P: not powering on, not charging.
                by djtaotao
                Hello guys, I need some help for troubleshoot my personal laptop. It's my first attempt to repair a laptop, I have good soldering skills and basic electronics knowledge.

                Dell Latitude 7430 - not powering on, not charging.
                The USB charger is negotiating the voltage and the USB meter shows 19.98V and 0.08A on both ports.
                When I plug in the charger the led on the power button lights up and stays on for 30s, turns off for 1s and turns on again for 30s and so on.

                The main power rail is done by ISL9538, without battery I have +8.6V and with the battery plugged in...

                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...

                Dell Latitude 3500 not charging
                by SarcasticOP
                Greetings,

                I am working on a Bolt-L UMA MB 17938-1 board for a Dell Latitude 3500 and it is not charging. Plugging in the barrel jack and USB-C both results in about a .1a draw at 20v. I probed around and checked every capacitor I could find, as well as the inductors, and I got no shorts, so I checked to see if anything was happening under the thermal camera when plugged in and I see a slight bit of heat being generated by the Intersil 9538H IC, which appears to connect the battery to the charging line, but I may be wrong about that, I am not very strong on reading schematics, I mostly...

                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.

                Pictures of these boards:
