Starting several months ago, my X220 either goes into bootloop if docked, or it boots but doesn't recognize USB devices. I've gone into BIOS and changed any setting i thouight might be related - boot order, USB setting UEFE/Legacy settings, etc. UI've gone back to defaults, then tried other combinations. No luck.
If I boot untethered, all is well and it recognizes USB devices once docked.
Anyomne have any ideas?
