My Sony Walkman NWZ-A818 wont switch off Connecting to the PC I can see the device in explorer and delet items but the device is in limbo in that I cant switch it off from the welcome screen

The Sony NW LATER NWZ-A818 is a portable media player that was released in 2010. It may work with Windows 7 and 8, but it's officially supported only for Windows XP and Vista.
You can try to connect the device to a Windows 7 or 8 computer and see if it is recognized by the operating system, but if you run into any issues, it may be difficult to find troubleshooting solutions as the device is quite old.
It's always recommendable to check the device's official website or the manual to check the compatibility with the operating system you have.
It's also worth noting that newer versions of Windows may require additional drivers or software to be installed in order to recognize older devices like the NW NW LATER LATER NWZ-A818.

On the back of the player is a very small hole. Take a paper clip end and gently push into the hole to re-boot it. Try this and recharge for a while.

Use Windows Media Player 11 or the Media Manager for Walkman.
For the media manager from Sony see the downloads in the support page (first select your operating system to make the downloads appear)

Before transferring videos use the Content Transfer softwarein the downloads.

Press and hold the Back/Home button for several seconds - see if the Settings Menu appears. Go to Video Settings and turn off the On-Hold Display.

If you go onto 'my computer' when its connected, you should see a thing for the mp3 player, open that and you should see all the files you have stored on it, and you can delete them at will :)
