Re: Dell
A American's bug: Mark II computer at 1947,
A British's bugs: Mark 1 1943. Colossus was the world's first programmable electronic digital computer. British codebreakers used Colossus to help to read German coded radio messages during World War II.
The first machine, Mark 1, worked in December 1943. It solved its first problem at Bletchley Park on 5 February 1944. Colossus Mark 2 was even better. It first worked on 1 June 1944, just before the Normandy Landings on D-Day.
PS: "Colossus" used many vacuum tubes (valves).
PS: Mark I was designed in 1937 by a Harvard graduate student, Howard H. Aiken. It that possible US helps UK build the Mark 1 and 2 to codebrake Germans code? Anyway, We are bodies in WWII.

by BowlineMy 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... -

by diamonI 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.

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... -
by trix11I have a Dell Precision T1650 MT workstation (of the following spec.) that was bricked yesterday when attempting to update the BIOS from A27 to A28 per:
- https://www.dell.com/support/home/en...-t1650/drivers > Dell Precision T1650 System BIOS
- Dell Precision T1650 mid tower Workstation
- Xeon E3-1225 V2
- 32Gb PC3-12800E RAM
- 4Tb SATA HDD
- motherboard: Dell part: 0C3YXR CN-0C3YXR-72200-39C-01GR-A02
I see now that others have experienced like issues e.g.:
