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....

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 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...

**Need Help Unlocking BIOS and Hard Drive on Dell Precision 5820 Tower**

by federalhouse

Hi everyone,

I'm in need of assistance with a Dell Precision 5820 Tower. The BIOS is locked with "Dell Security Manager," preventing access to the HDD-1 hard drive.

**Background:**

I recently purchased this Dell Precision 5820 Tower from a recycler who salvages equipment from abandoned office spaces. The computer was left behind by its previous owner and was password locked. Given that it can run Windows 11, I saw this as an opportunity to upgrade my setup.

**What I've Tried So Far:**
