I am still trying to find an industry standard for connectors and leads on modular computer power supplies (internal type) - and I doubt there would ever be an industry standard, because it is apparently specific to a manufacturer and/or series.

My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics. -
Re: Standardization for modular internal computer power supplies
Each manufacturer tends to standardize their own cables to a single format.
In the past it was no possible because everyone had to work around patents related to modular cables (I think Ultra had some patent on modular cable)
http://www.google.com/patents/about?id=w0ehAAAAEBAJ
http://www.google.com/patents/about?id=iOGqAAAAEBAJ
So they had to carefully make the modular connectors around what the patents claimed.
I'm not exactly sure but I think the Ultra patent was invalidated... but I may be confusing the patent with the one for 140 mm fans.. there was one for this stupidity, and because of this a lot of manufacturers advertised 139.5mm fans on the packaging.

Hello everyone,
I have a Lenovo V15-IKB that had a damaged motherboard. I replaced it with a motherboard from a Lenovo V15-IIL.
The board powers on, but it shuts down after about 10-15 seconds. This only happens when the internal display (LCD panel) is connected.
Here's what I've tried so far:- When the internal display is disconnected, the laptop works perfectly fine via HDMI.
- The laptop shows an image on the internal display for a few seconds before it shuts down.
- I tried swapping the LCD panel with a known good one.

Hi all.
I have an asus F505DV that has a smashed screen, broken hinges, bezel and top cover.
The customer cannot afford to repair it, so they wanted me to remove the top of the unit and will just use the base as a desktop and plug into a monitor via HDMI.
However, for some reason, with this model, it REFUSES to display on the external monitor unless there is also an internal LCD.
If there is a internal screen, then the external displays fine.
This is running the latest BIOS.
I have set the display properties in windows 10 using... -
Hello there,
I have a SF314-41 motherboard that i bought impulsively recently, the problem is that i only bought the motherboard only, nothing else. When i tried powering on the board with 19V (soldered on the DC IN port), and then shorting the pin 1-2 of the keyboard, the board is turning on (as indicated by the fan), however it seems like the board is displaying on the internal display as connecting to a display on the HDMI (external) does not display anything.
I tried connecting a USB keyboard, the keyboard is powered on, however pressing numlock do nothing (supposed to toggle... -
Hi! I have a Razer Blade 15 2022, with a RTX 3060.
One day, while using Linux, the internal display suddenly stopped working.
On Windows, it says that the internal GPU has stopped working (with error code 43).
I have tried removing the coin cell and the battery, and replacing the RAM, with no success on fixing anything.
I'm looking for directions to fix this problem, and, first of all, I would like to be able to access the BIOS and change some settings (which is currently impossible as it is always shown on the internal display). There is a setting...05-29-2025, 07:01 AM -
