    Check RTCRST# and SRTCRST# voltage. No power should be attached to mb(adapter+battery removed), only 3V cmos cell inserted.

        Dead Dell Latitude 5420 not receiving 20 volts from USB-C charger
        by BTubbs200
        Hello,

        Dell Latitude 5420 P137G
        Board: LA-K491P REV A01

        I have received this laptop which was described as "does not power on or accept charge." Battery shows no sign of charging when charger is plugged in, nor does the board show any signs of life when battery is unplugged and charger is plugged in. No light from the LED at all or any other indications of activity.

        Board seems to have no shorts, all power rails are fine and show high resistance.

        When charger is plugged in, voltage is present in 3.3V rail but absent in others....

        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.

        Pictures of these boards:

        Dell 5410 greyed out BT
        by OntarioTL
        Well I've learned something new today. Of all the Dell laptops I've come across I have never seen bluetooth greyed out, and only to learn this is during the build from Dell factory. I've tried to pull the original BIOS and fix with another dell with the same issue on the forums, however the original was not recovered from the forum upgrade so I cannot do a comparison to attempt the fix on my own.

        If someone could help me out with this unit and I'll try the next one as so far I have 2 on my desk with this issue. Thanks in advance!

        Dell G5 SE 5505 - "Invalid memory installed" after BIOS update.
        by lalle-
        Hello!

        I have a problem with a Dell G5 SE 5505 laptop that I hope someone can give me a few pointers on.
        [OK, it's not really a laptop, I'm running the motherboard on my desktop with only cooling, RAM and an M2 drive attached.]
        I had some performance issues, so I decided to update my BIOS from 1.7.0 to the latest version, 1.20.0.
        The computer restarted and the update dit not want to continue without a battery connected, even though I used dell's method of bypassing this requirement.
        I tried updating to a custom BIOS from Reddit user Satori_Nori https://www...
