How to open / disassemble Sony Walkman NWZ – B133F

I was not using my Sony walkman for last 3 months.
After keeping it  idle for three months, finally one fine morning I pick it up for my exercise regime (which I was planning for the last 6 Yrs), to find out it was not working.
I think the battery discharged beyond its safe limit. As every cell requires a minimum residual charge to pickup the charge. Even though it was not switching on, transferring of files to the device or upgrading the software was not an issue, as it was getting detected on computer.
I searched internet for opening procedure of the device for disassembling it, as I could not find any screws or locking mechanism. After trying all the method and staring the device a lot, I got frustrated and break open it.

The green stuff sticking outside is the battery.

    Thanks. Mine was accidentally washed (in my pocket) this morning, and this helped me get it open so I could dry it out 🙂

    I really love this mp3 player (it fell from 4th floor on a concrete, dive into a bath and after all these adventures it still worked! I suppose that I’ll never find a player like that)
    but now i have o problem when trying to connect to usb – sometiomes it “disappear” – i guess i will have to check what’s going on inside, so thank for showing me how to get in there!

      As Per sony Repair Centre in Chennai they will not touch the device with the longest pole.They are also unhelpful to the core to know where the battery can be bought!
      Very poor after sale service for Sony Walkman even if you are a DIY buff.
      Therefore I recommend that you make a parallal connection outside the device by proper extension and proper supporting(Jugad) and connect a Li Ion Battery of any Mobile phone properly.That way you will have a long service between recharges,But slightly bulkier.That’s Swachch Bharath!
