I know what is the problem. Met it with replacing the mobo on another machine. IT IS THE RIBBON WIRES ENDS A THE CONNECTORS, FOR SURE ! Just very carefully cut off about a 1/16 at the end . Then the clamp will find fat trace wires and all will work just dandy. THEN to keep the ribbon from wandering around then tape it down with some really good tape, like duct tape. This WILL work.!

As suggested can you attach a ps2 mouse and keyboard, if as you stated reseated the keyboard and palm rest, were the connections good, not broken bent. The possibility of the key board and palm rest not working does not sound to me initially that the board is faulty. What type of machine is it? and what type of operating system are you loading. I may have missed that part forgive me. However this does not sound like a mobo failure, I am suspecting something minor than that, trouble shooting begins!!!

Have you tried an external keyboard & Mouse? If you have tried all above it is possible you have a problem with your motherboard keyboard controllers. Try resetting the Motherboard by removing the power / Battery and CMOS battery from the motherboard and press and hold the power button for few minutes.

Check in your device manger ensure that you have all the drivers for the machine. You can run this driver identifier and check and see what you are missing it will also tell where to get the drivers from.

I have the Arduino IDE installed on an older windows 10 laptop and all works fine. Today I tried using my new Windows 11 laptop and the Tools -> Port option is grayed out. I'm using verion 1.8.19 of the IDE, the most current I believe, and I'm trying to connect to a UNO. I've searched the Arduino forums for like issues but found none.
The Port option from the Device Manager has disappeared. The new procedure, as much as I can divine from YouTube videos, is to go the firewall manager and define an input and output rule, although I'm not certain this is the correct approach, and it didn't resolve the problem. Just to cover all bases, I ordered a new USB AB cable to rule out that possibility.
I'm looking for any hints or approaches to fixing this. Thanks in advance

I have the same issue on an Acer laptop (2019). I have the impression that the problem is in the serial io driver for the laptop (I don't see "ports" in device manager). If I look on the acer site, I only see the windows 10 drivers for this laptop and trying to install the serial io driver it says "not compatible with this platform (I guess windows 11 is meant here)

yes, I tried to install the win10 motherboard (Acer) driver. As said, it gives "not compatible with this platform" error, I guess because it is the win10 driver for serial io. There is no win11 serial io driver for this laptop.

So, one bit of information. In Win 11, the device manager has a VIEW option of "Show Hidden Devices'. How convenient of Microsoft to hide things you might want to see. Once I checked this option, I can see the Ports in the device manager and it shows Arduino Uno (com3). I also installed the CH341 driver from NanjingQinhengMicroelectronics as described in a previous post. The install runs successfully although I can not see any results in the driver description shown under the Port listing in the device manager.
The Device Manager in Win10 says "Standard Serial over Bluetooth link (com3)" , no mention of Arduino. Strange.
Anyway, My issue is resolved, I ran the blink sketch from my Windows 11 laptop and it works. I'm not sure which step solved the issue but I appreciate everyone's indulgence. Thanks

well, I found my issue...after I did everything logical I started to look at illogical things.
So the cable that I have been carrying around with my laptop for some time, to connect drives and camera's (and NodeMCUs and arduinos) apparently decided to fail at the same moment I switched to win11 . I changed the cable for another and everything worked fine again. Then tested that same cable to connect my camera to the laptop...and it works just fine. I test it again with the NodeMCU, it fails. Something odd is going on with that cable, I will dump it.

Reminds me of the time when I still worked for Ericsson and everybody said a serious problem we had to be a SW error and we checked everything 3 times and couldn't find it. At some point I said: "lets just change the hardware". Nobody agreed because all tests showed the HW was working fine but I managed to convince them to at least give it a try. As that HW was hard to get at that time we had to halt the test of another machine to get the right hardware. Et voila, everything worked fine after we replaced the hardware.We inserted the original board again and our SW failed again.The board was send to a special department to check it and nobody could ever find something wrong with it.
