Hello guys. I have a problem with a PNY XLR8 GAMING RTX3090 graphics card. The problem is that it displays and works fine, but the fans don't spin at all. The problem occurred when someone else removed the fans in order to clean it and broke one of the fan connectors. He replaced it himself and after that, it wasn't working anymore. I guess he damaged something else in the process. What i have done so far: I found 2 capacitors next to the connector that were in a bad shape, he must have touched them with his tools - they weren't shorted, but i replaced them with similar ones from a similar card....04-12-2024, 06:54 AM -
This audio chipset has been a pain to deal with, most of the time its impossible to find drivers for chinese laptops that have no name/brand, or generic rebranded laptops.
Huawei also started to use it BUT they no longer host drivers on their website since they want you to force their PC manager app that often refuses to install after bios flashing and apparently the generic drivers around wont work on some intel systems and others wont work on amd systems, the generic ones have worked only once and i think i have had this problem on 30+ laptops so far in the last year.02-21-2025, 12:33 AM -
Good Afternoon, Good People.
I know this will be an elementary little project for most if not all of you, but I thought I would write a post and get put on track, rather than bumbling my way through it with all kinds of trials and errors.
I REALLY would appreciate y'alls help.
This is the problem - My wife and I purchased a big ol Victorian/Colonial House in NYC two years ago. The kitchen is surrounded on 3 sides by exterior walls, there is also a 1/4 of the kitchen floor (ceramic tiles) that has a crawl space underneath, and the kitchen gets FREEZING cold... -
For the second time this week I received a Lenovo laptop with onboard ram and one sodimm slot. Both laptops run stable from their onboard 4GB RAM, but turn out to be very unstable when there's a sodimm inserted in the slot.
Both times it was a GS44D/GS54D NM-C711 rev 1.0 board.
Both times there were no loose pins on the slot and it did not matter what sodimm I put in. It just artefacts and crashes randomly when there's extra ram.
What I did notice is that almost all coils have very dirty phases one the mosfet side when checked with an oscilloscope. Not something I see very often....06-07-2024, 09:16 AM -
Hello Everyone,
I am looking for schematics of good quality laptops and tablet with 11th gen CPU.
I'm an engineer and I'd like to study them.
I can find:
- Macbooks
- Surface laptops
Does anyone have any schematics of 11th gen Dell XPS laptops, or other good-quality premium laptops and tablets?
it would be much appreciated!02-08-2022, 07:28 AM
