How do I get the battery out to replace. player

Hi chasruthdorm,
The battery can be changed only at Sony service centers, as per the manual. Please take it to a nearby Sony center to evaluate if you indeed need a battery change, and get them to do it right away.

Kendogaruru is incorrect.You CAN change the battery in a Sony Walkman NWZ-S616F MP3 Player yourself.I just successfully did it myself today.You just need a set of jewelers screwdrivers and a sharp point tweezers - and a small pocket knife with a thin blade might help too - and a fair bit of patience.And if you have older eyes, a set of reading glasses.....

Order a 'Cameron SinoCS-SA615SL' battery (eBay / Amazon).Once you get the battery, to start, remove the oblong Sony label at the bottom back of the MP3 player.It covers the two screws that hold the front of the case on.If you are careful, you can re-use the label with the MP3 Player ID #, and maybe tape it back on later.

Use your smallest phillips screwdriver, or a very small flat blade, and remove the two screws from the back.Place them in a cup or bowl so you don't lose them. Take your small flat blade screwdriver, or small pocket knife blade, and starting at the bottom, gently pry up the top half of the case till you get to the top corners - STOP THERE!!!Then, gently lift the bottom of the top case between your fingers - and slide the case up. DO NOT LIFT the top!The top corners have lips on them to hold the top case in place. You will snap them off if you try to lift or pry the top of the case up - and then you are pretty much done. The top case may be somewhat stuck with a little copper strip on the screen like mine was. It's not glued, and with some gentle rocking, it should separate. Be VERY CAREFUL removing the top cover as it is connected with a very small ribbon strip, and you don't want to yank it or rip it. Leave the ribbon strip connected.Fold the top cover over, exposing the screen and circuit board in the bottom half. The battery is below the circuit board that the screen is on. Also, be careful not to lose or misplace the plastic screen protector in the top case.

There are 5 very small screws to remove now. Four of them hold the screen down at the corners - remove them and put them into the cup. The fifth screw is at the top center and holds the circuit board in place. Remove it and put it in the cup also.The screen will fold over to the bottom, but be careful not to scratch it. You don't need to fold it over, but it's ok if it does. Again, be careful and gentle with it.It is also attached with a thin long ribbon strip that you don't want to rip or remove.

To remove the circuit board - gently lift the bottom of the circuit board and while lifting and rocking, pull the circuit board to the bottom of the lower cover to get the headphone jack out of its hole. Be careful not to lose the 'volume' and 'hold' switches from their places. It's pretty obvious how they go back in if they fall out though (hint - the rounded corners go down). Also, there is a plastic frame piece that goes below the circuit board at the bottom where the usb charger cord plugs in - and a metal one on top. It's a good idea before you start trying to remove the circuit board to make sure you will remember how they go back on. Again, it's pretty obvious though.

Once the circuit board is out, you will have exposed the battery in a recess in the lower case. You will want to use the tweezers to gently remove the battery connection - male end. Make sure to check which color wire goes where for when you reassemble. The wire connections should be on the top of the connector.Also, the battery wires may be taped down onto the circuit board. Using a small jewelers screwdriver and the tweezers, remove the wires from the tape. This will help you to be able to remove the circuit board too.

The battery is securely taped in with some sticky goop. You will need to gently but firmly pry the battery up using a combination of a flat blade screwdriver and your small pocket knife blade. Be careful!If you bend it or puncture it, being a lithium battery, it could catch fire. I bent mine a bit, and it started getting warm. This will be the most difficult part of the battery change. And you don't want to pry too hard as you don't want to snap off any of the little plastic prongs in the lower case, or puncture the back of the case. Remember - it's somewhat soft plastic.

Also, there are silver rim edge pieces that you will need to keep track of. If they have fallen out, during reassembly, there is a right and a left one. They are not interchangeable.They have little lips that go around the corner pieces of the lower case, and they go under the circuit board.

Reassembly is essentially the reverse of the disassembly. Just remember that when you plug the new battery into the circuit board, to keep the + & - wires on the correct side. And make sure to pull the battery wires with your tweezers straight down under the circuit board and do not let them jut out to the side. If they do, it will prevent reassembly.I didn't tape mine back down. I just folded them back into the same space they were under the tape.

You will probably want to wipe down the screen with a clean soft cloth before you put the top case on. You probably got a bunch of finger prints / smudges on it during disassembly.

DO NOT force anything during reassembly!It does all fit back together pretty well. If it doesn't seem to be fitting, back up and take a break, and check out how things are going together. There are a couple of little plastic guide pins that need to be lined up for some of the frame items. Also, my new battery had a plastic covering that was a little bit thicker at the bottom than the original. It eventually did compress enough though.Just take your time.

I hope this helps someone. I had to figure this all out myself, but my NWZ-S616F Walkman MP3 Player is working just fine now with its new battery!
