Ledger Button Not Responding | Entry Check, Screen State, and Service Record
If a Ledger button is not responding, start with a narrow check: confirm the page or app entry, observe the device screen, and record the visible state before changing several conditions at once. The goal is to separate a connection or prompt issue from a device-control issue.

Direct Answer: Keep the Check to Device and Entry State
A button that does not respond should be checked in the same order each time: entry page, cable or port, device screen, then the local record of what changed. This keeps the answer tied to observable state instead of turning one symptom into several guesses.
Confirm Cable, Port, and App Prompt
Use a stable entry and check whether the host app can open the device. The connection path in Ledger Wallet cannot open the device helps separate permission, cable, and device-screen checks without mixing them together.
Use the Device Screen as the Decision Point
The device screen is the place to read the prompt and decide whether the button is being asked to confirm, cancel, scroll, or wake the device. For the hardware boundary behind screen confirmation, compare the state with Ledger Secure Element basics.
Prepare a Service Record if the State Stays the Same
If the same screen state remains after one cable, one port, and one restart check, stop changing variables and prepare a concise record: device model, entry path, screen text, cable type, and the next step. The daily flow in organizing a daily Ledger use flow gives a clean format for that record.
Do not write down PIN digits or recovery phrase words in the record. Keep the note limited to the entry source, visible prompt, physical button behavior, and whether the same result repeats after one controlled change.
