Re: 3 Dell 2208WFPF with bad lamp assemblies
I have one of these monitors and it also had crispy wire connections as shown in your pictures. Out of curiosity, what causes that white wire to cook at that particular end of the CCFL? The caps in the inverter section of the power board looked OK (superficially), but I ended up recapping the board before disassembling the LCD module, just to see if that was the problem (crappy Leion and Su'scon caps anyway). -
Re: 3 Dell 2208WFPF with bad lamp assemblies
Poor solder connection, if you look real close, the solder is crystalized and hard as a rock, it generated lots of heat due to poor connection (poor contact resistance) so it gets hot and burn.

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... -
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.

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.

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... -
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!
