I have 2 Dell 2408WFP monitors. For the past few days when I turn one of them on in the morning for the first time it appears to be 20-30% dimmer and within 10-15 minutes it gets brighter and remains that way until I shut it off for the night. I haven't opened it up yet. Just wondering what the symptom could be.

Re: Dell 2408WFP
Description suggests bad caps. With the back off try heating the boards gently with a hairdrier to see if you get it brighter quicker.

Re: Dell 2408WFP
Could also be old tubes. Room temperature also affect fluorescent tubes brightness at startup.
Try starting it and going to an all white screen. Notice any pinkish hue? If so, I'd bet on the tubes starting to weaken.
Not sure of the style used in the 2408, but the 2407 uses 6 "U" bend tubes @ $20 each.

Re: Dell 2408WFP
Sorry I havent had time to open the unit up. This morning when I was using the monitor it had green dotted horizontal lines and the screen was moving left and right. When I read a pdf with a gray background the green horizontal lines disappear but the screen still shakes left to right. What does this sound like?Comment

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... -

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.

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...
