Ugreen HDMI splitter missing a pulldown resistor

[spleenharvester]

Odd one I've found. This splitter likes to cut out - on my Xbox Series S the display/audio would randomly go to black for a few seconds - on my PC the monitor would flicker several times before eventually staying on. A few others have reported similar issues. Couldn't be bothered returning it for the sake of £8.

I pulled it apart and found it is driven by a Texas TS3DV642 mux/demux. There appears to be a missing pulldown resistor on the HPD line, it is just left floating. Adding a 100K pulldown to ground fixes the flickering.

(Not that this is worth the hassle for an...

My laptop has a GTX 1060 installed, but it is not recognized in the BIOS (see attachment). The chip gets warm and the fans spin. I think there is an error in the BIOS.
Could there be a switch to activate/deactivate the graphics card?
I am also unable to install an Nvidia driver in Windows.

Data about my motherboard:

S/N: 1TP670RP6310404
P/N: 6-77-P670RP6A-N02A-B#10

If anything else is needed, just let me know....

Hello,
I have a Lenovo IdeaPad 5 14Itl05 with a short circuit in component "UH1," an "S IC AP2330W-7 SC59." I haven't found any datasheets for this component online, but I have a similar one labeled "AP2331W-7."
Can anyone please tell me which component it is?
If a compatible one is available, and where?
Thanks....

Hi,

I got two HP Mini 800 G5 machines, both 65W mainboards (have all 12 FETs populated on the CPU power rail).

One board is always throwing errors in MemTest86, no matter which known good CPU/RAM combo installed. Board is fried. Period. Will be scrapped.
The defective board contains a Win10Pro license in BIOS.

The other board is working perfectly fine, but only includes a FreeDOS "license".
I want to transfer the Win10Pro license from the fried board to the working one. If that includes transferring S/N etc, I'm fine with that, will...

I have two of these mini PCs: TrigKey S5 with Ryzen 5700U, 32GB RAM, 1TB NVMe SSD, Win11 Pro. They work very well for most uses. They are powered by a HuntKey 19V 4.74A brick with a standard DC5525 tip, which feels decently heavy.

When the brick is connected to the system through a 1 meter DC female-male extension cord (18AWG so decently thick), the system will black screen and reboot when multiple objects are sliced simultaneously in PrusaSlicer. One object is OK. Literally any other activity on the PC is OK. It is just this one specific thing that causes a reboot. I tried running...

hi
i bought a defective legion, tested it had the IT8227E-192 CXA shorted.
I ordered on aliexpress, carefully changed it under microscope, and now when i plug the dc in, keyboard flashes in all colors in loop, on button is white, and nothing more
The battery led is charging, it seems is the only thing that works
Screen is off, nothing, not even the backlight
could it be a non programmed IT8227E ?
Awaiting for your feedback
Thank You
Stefano
