Troubleshooting

Video works but your KVM keyboard or mouse does not? Check host cables, USB ports, wireless receivers and Mac permissions before replacing hardware.

New SSD missing from File Explorer or Disk Management? Identify the problem, check the slot or enclosure, and avoid erasing a drive that holds files.

Game audio turns muffled when a call starts? Check the Bluetooth mode, mic routing and LE Audio support before buying a new headset or adapter.

Steam Deck dock shows no signal? Try external display safe mode, isolate the cable and power path, and check the evidence before replacing your dock.

A KVM black screen is usually a signal-path, bandwidth, wake, or EDID problem. Use this order to isolate the fault without replacing everything.
