You cannot charge your Walkman.
Charge the battery within the ambient temperature range of 5 °C to 35 °C (41 ºF to 95

There may be bad electrical contact in the connector. Disconnect your Walkman, and
then reconnect it.
Use the supplied USB cable.

computer are compatible with your Walkman.
The battery may have deteriorated if you have not used your Walkman for more than a
year. Contact your nearest Sony dealer.
