My NWZ-B152F walkman does not work

[sim1986]

Hello everybody! My NWZ-B152F walkman was working properly till today. I was listenig to music and I pressed the pause/stop button to turn it off. The screen read power off, but the player did not turn off. The screen continued to read power off and the buttons of the player did not function. I tried to connect it to the computer but it is not recognised. I tried also to reset it using the reset button but with no results. Now I can't use my player because the screen permanently reads power off and the player does not respond. I know this is quite an uncommon problem, but would anyone please help me?

I found walkman few days ago as dead condition in my old desk , i was tried so many times but no result, however i tried your given method and i m surprised that this is still working. Thanks again.
