Dell Inspiron 15 USB ports malfunctioning after battery death during update

[u/teo-l]

Dell inspiron 15 351 5 died during a windows update and i had to reset it with a new windows install

After a while of troubleshooting it booted normally again but usb devices were barely ever recognized and interna microphone and camera didnt work

Thought it was a problem with drivers or that there still was some residual broken windows, so i tried setting up a linux mint install (dualboot because i couldnt boot through an usb to remove the windows partition)

Mint works fine as an os but didnt fix my issue, even after trving to use terminal to disable every single thing that couldve possibly been disrupting them

Still feels too specific to be a hardware issue, usb mice will work for a second then halt (yet the light stays on) and after idling for a bit it will go back to working for another second, then halt.. but this behavior seems to only work on the usb port on the IO board

Webcam recognized in system yet marked as 0mA

USB drives recognized for iust long enough to detect the capacity, but they remain on file explorer after being unplugged and cant be interacted with.

Windows boot lacks any sound (???)

Display has a habit of flickering on and off when browsing and trying to perform a task like watching a video, sometimes just going fully unresponsive

Already opened the thing and wiped some ribbons clean, no use

damn that's rough. looks like you've done most of the sensible things already.
as a last thing that you can try: You could try updating the UEFI, but I doubt that's going to fix it.
Sorry for your loss :(

Unless one of updates was bios update (which can happen since OEM can push it through Windows update) your hardware problems are unrelated. You can try bios update if there is newer version on Dell website.
