This Intersil IC - ISL88550AIRZ on Dell Latitude E6400 (RAM IC) has 19v, but no output - 1.8v. It causes the laptop not to display because of the voltage lacking on the RAM modules. Please, assist me to know the replacement equivalent for this IC. I have two laptops of same make with the same issue. Thanks

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'm working on an old Dell XPS410 with burst capacitors. I'm trying to source either an equivalent replacement, or a replacement that will work. It's been suggested to me to use Poly caps as a replacement, but I have no idea what to order or what will work.
If anyone has a link to where I can buy what I need that would be even better.
These are the caps that have burst:
Board location: C8BV, C26BV, C43BV
Brand: United Chemi Con
Series: KZG
Size: 10mm dia X 25mm height
Impedance: (ohms max/20c, 100kHz) .012
Ripple: 2800... -
Hi everyone,
I've got a little "problem child": my Dell Latitude 7420 2-in-1, which had a faulty mainboard.
I replaced it, but ever since, the touchscreen no longer works — and honestly, I’m running out of ideas…
In Windows Device Manager, I just see an I2C HID Device with error code 10. Sporadically, the touchscreen is recognized correctly for just a few seconds, but I haven’t been able to determine under which circumstances this happens.
The touchscreen also doesn’t work in UEFI/BIOS, although it’s enabled... -
Hi
I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.
1. FR950 - blown fusible resistor - 0.2 Ohm 1W
2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
3. R835 - Blown Resistor - 20KOhm SMD resistor
4. D930 - Shorted Schottkey Diode...
