Connect the Walkman to a computer or AC adaptor and charge it for about 10 minutes. If the problem persists, restart the Walkman.
- The charge lamp lights up in red soon after the Walkman is connected to a computer or AC adaptor, but the Walkman screen may not turn on if the battery level is insufficient.
- If you wait for about 10 minutes with the Walkman connected to the power source, the Walkman will turn on and enter the standby mode automatically.
- If the Walkman does not turn on even 10 to 20 minutes after the charge lamp lights up in red, restart the Walkman:
Hold down the (power) button for 8 seconds until the Walkman restarts.
NOTE: The procedure may differ depending on the model. For details, refer to the Help Guide of your Walkman.
