SanDisk Sansa Fuze
If your SanDisk Sansa Fuze is under warranty, stop here and contact the manufacturer. If you open the SanDisk Sansa Fuze, it will void your warranty. If it is not under warranty then proceed with the steps below. As with most small electronics, changing the battery is not easy. It takes time and some patience. You will need a knife with a length of ½ inch or less, an eyeglass screwdriver set, or you could use a jeweler’s set and small needle nosed pliers.
On a flat, clean surface find the small clips on the side of the SanDisk Sansa Fuze. You will find these clips in the creases on each side and at the bottom crease. The bottom two clips may be glued down. With the knife, gently press the first clip inward and gently pry the case apart. Do this for all clips one at a time.
Pull the top panel upward very slowly and gently. When you lift this panel watch for the ribbon cable. This cable holds the top and bottom of the MP3 player together. Take the needle nosed pliers and grasp the bar of the cable that is attached to the top half of the MP3 player. Disconnect the cable from the socket. Make sure you only grab the bar on the cable and not the wires. At this point the top plate should be completely removed from your SanDisk MP3 player.
You should see the battery on the back plate of the SanDisk player. The battery is flat and rectangular in shape and has one red, black and white wire on one side. Use the jeweler’s screwdriver and very gently pry the battery off the sticky foam. Take the new battery, press it in the socket and reconnect the ribbon cable back into the socket. Next, line up the top and bottom of the plate and make sure the clips line up and press the plate down to the bottom plate. Do not be forceful but press gently. Snap the clips back in place one at a time.
