If you are using SONY's Walkman NW-A45 and your battery (battery) is stuck in the battery, or if the power is no longer turned on, it may be improved by replacing the battery.
I will publish the decomposition method, so I think that you can refer to it if you want to repair it yourself, but solder work is necessary to remove the battery.
In addition, since soldering of the battery will be a dangerous work, check the decomposition process and it is severe for yourself!If you think that repair shop, manufacturer, etc. it is recommended to consult.
The battery of the iPhone and the smartphone can be easily replaced with the battery because there are many cases of connector connection rather than solder, but the battery replacement that requires soldering is often more difficult to repair, so be careful.
When we checked the manufacturer's (SONY) Walkman repair price (battery replacement, battery replacement), the NW-A45 was 6800 yen (excluding tax).

The battery of the NW-A45 is internal and must be disassembled before it can be removed.
It is very stylish because there is no screw on the outside, but you need to find a place to trigger the disassembly.

This is the upper side (SONY logo), but there is a seal and cover of the same color body, so I will open it from there.
Let's peel off a little by using the tool as shown in the image.
If it is a little hard, it is easy to peel off if you lightly apply heat with a dryer or heat gun and then disassemble it.

If you can float even in one place, let's try to peel off by sliding carefully.
Please note that if you proceed with the decomposition forcefully, it may break because of the plastic.

I was able to remove the upper lid, but you can see that it was fixed only with double-sided tape.
[Walkman NW-A45 battery replacement 5]
It becomes the lower side (dock connector side) opposite to the previous, but it is also fixed with tape, so i will peel it off by the same procedure as before.
[Walkman NW-A45 battery replacement 6]
Let's insert and peel off the tool as shown in the image.
[Walkman NW-A45 battery replacement 7]
The upper and lower sides are only affixed with double-sided tape, so you can easily peel them off.
[Walkman NW-A45 battery replacement 8]
It is not on the upper side, but there are two screws on the lower side.
Let's use out the thin Phillips screwdriver at the tip.
[Walkman NW-A45 battery replacement 9]
I'm opening the cover a little bit, do you understand?
[Walkman NW-A45 battery replacement 10]
I took a picture from a different angle, but I put a spatula into this gap and disassembled it.
[Walkman NW-A45 battery replacement 11]
The back cover is fixed with double-sided tape and plastic claws, but it slides a little bit.
[Walkman NW-A45 battery replacement 12]
Since there is a double-sided tape from around the middle, let's insert the spatula while checking the inside.
[Walkman NW-A45 battery replacement 13]
I was able to remove the back cover.
[Walkman NW-A45 battery replacement 14]
I don't see the battery yet, but there is a battery under this silver plate, so I will proceed with the disassembly.
There is a screw in the part surrounded by a red frame, so let's remove it.
[Walkman NW-A45 battery replacement 15]
It is opposite to the previous, but let's remove the screw of two places.
[Walkman NW-A45 battery replacement 16]
Remove the plate by inserting the tool into the gap and lifting it.
[Walkman NW-A45 battery replacement 17]
Let's float because the cable of the battery enters the gap of the part.
[Walkman NW-A45 battery replacement 18]
Place the cable on top.
[Walkman NW-A45 battery replacement 19]
Remove the orange wiring, but pull the connector claws to 90 degrees before sliding the cable.
[Walkman NW-A45 battery replacement 20]
You can remove the cable in this way.
[Walkman NW-A45 battery replacement 21]
The part where the connector was stuck earlier is attached to the silver plate with double-sided tape, so let's insert the tool down and peel it off.
[Walkman NW-A45 battery replacement 22]
If the tape is hard, it is easy to peel off by using a dryer or heat gun and warming it.
[Walkman NW-A45 battery replacement 23]
Remove the silver plate, but gently lift it from the bottom.
[Walkman NW-A45 battery replacement 24]
I was able to remove the plate, but the battery does not come off completely because it is soldered to the base.
[Walkman NW-A45 battery replacement 25]
Because it is soldered to the base, it removes it using the solder.
[Walkman NW-A45 battery replacement 26]
It is in the state that the distribution has been removed.
[Walkman NW-A45 battery replacement 27]
I cleaned the base using the solder suction line.
After that, if you prepare a battery to be replaced and incorporate it in the original procedure, the battery replacement will be completed.
Summary
How did you like it?
I think that it is possible to respond without problems if there is a thing that the solder repair of the base was done even once, such as a personal computer, but it is not recommended for those who use solder for the first time.
I apologized and exploded the battery!Please check various risks so that it does not become a thing.
