Evening all

So I have a Dell laptop (inspiron 5415) that I use for mainly docking and doing light CAD work on when I dont need my PC

However recently its developed a very strange behaviour on the USB C. If I plug in a USB C dock/charger when the laptop is on nothing happens. but if i plug it in while the laptop is powered off it will charge and if I then turn the laptop on the dock will work if its already connected whilst being powered on. I did install some software that wanted some net framework thing (typically did not read what it was) installing and it seems to coinside with that being installed but for the life of me I cannot remember what the softare said it needed to update. I have tried Dell update and windows update and everything is Up to date. However the USB port is dead as a door nail if its not plugged in whilst turning it on. Im loath to reinstall windows but I do feel that will resolve it. any ideas?
 
Would really need to know
What you installed/updated
Do you have system restore turned on?
Could try rollback to before you installed it
If its on
Otherwise it's look in add/remove programs features
And see if you can figure out what it was
And remove it

You should have some sort of image backup
So much faster than reinstall windows
Then reinstall all your software etc
Literally under 3 minutes for me as got all m2 nvme drives

Yea I cannot for the life of me remember the software that it installed. I know the main bit of software but I have tried to remove that with no luck. It was some soft of .net or something driver that the software called for but cannot remember and reinstalling the software its not asking for that module again. :(

My guess would be
Netframework 4
Programs like AS SSD require it
And open the dialogue box to download it
 
Not sure if it's worth trying to do a BIOS reset(?) Not been mentioned, but not sure if it's been one of the updates which might have been done?
 
So reset the bios to deault settings, also updated the bios, formatter the HDD and resinstalled a fresh W11 install and still have the same issue. USB C totally dead once windows is loaded. However if a device is plugged in when you power up the laptop its fine. Can only assume this is a hardware fault now on the USB controller. just got to decide if its a fault I can live with or not.
 
Have you tried looking to see what or if it's even detecting what you plug in when the laptop is on?

Best program I've come across for troubleshooting USB problems is...
With that running when you plug in the device it should auto-refresh/detect what you've just plugged in
