I have seen the same weird bug on three different Mini PCs from three different manufacturers. The problem was that normal letter keypresses would be converted by each PC to their control-key values. For example, a lower case "s" would be converted into a "control-S" value. This substitution occurred about once every 200 characters typed, but not consistently. Sometimes it was in the same sentence and I even saw it happen twice in a row. It would happen for any character. When typing in Notepad, this is very disturbing because a lot of control keys pop up windows like open-new-file, search-and-replace, select-all, etc. It would happen in any application where I was typing some input. In Chrome, Edge, and Firefox.
The first PC was from Kingdel, the second was from Minisforum, and the third from Geekom. All three had to be returned to Amazon after trying to find a solution with the manufacturer's technical support team. I know I wasn't accidently hitting a control key, because I built small shields to cover them! PowerToys was not installed, so there was no key remapping. In the last case, I even built a Windows 10 iso flash drive to load Windows 10. The bug was still there. Tried multiple good keyboards. Tried changing USB ports. Finally, I just gave up on mini PCs, and bought a Dell Inspiron. I've been running that for several days now, and I have not seen a single instance of this bug.
All three were generation 11 or 12 Intel i5s. Was this a bug in the chipset all of them were using? Was it because my cellphone was too close to these little mini cases? How come I don't see it with the Dell?
