I want to say first, thank you to this site and all it's members for the wealth of free and shared information. I am brand new to this site and new to electronics. I found a Dell 1905fp monitor at the junkyard, it looked good so I took it home. I found it would not turn on at all. I did an internet search found this site and replaced (3) 1000uf 10volt caps that looked bad that I ordered from digikey (they were awesome, received my order in 2 days). Put the monitor back together and when I plugged it in the screen turned right on, the analog test box floats around the screen and the monitor will show a display when hooked up to a analog signal but not through the DVI. My main issue is that the Control buttons do not work and the power led does not light up. I have checked all connections and everything looks good. Could other caps be responsible for this, or is it most likely the control button panel. Thanks to all.

Dell Latitude 3510 (Intel Core i7-10510U) CPU Overheating
Issue Description:- CPU Overheating to 100°C
- When I start the laptop from a cold state, it takes about a minute to reach temps around 80-90-100°C, and CPU thermal throttling triggers.
- When the CPU fan is running at full speed (by disconnecting PWM and TACH cables), CPU temperature stays around 50-60°C.
- However, when the fan is connected normally to the motherboard, it does not kick in at high temperatures.
- I also noticed a few times that the fan kicked in for a very short time, but it does not stay on consistently.

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 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:

Hello all,

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:
