I NEED THE CHART FOR MY Z313 LOGITECH SUBWOOFER

https://www.logitech.com/en-ca/product/speaker-system-z313

The speakers have a 3.5mm stereo jack, does your tablet have a headphone output? Connnect a Male-Male 3.5mm stereo cable between the two, The Logitech does not have Bluetooth or USB, so if you do not have a headphone output, you can purchase a Bluetooth receiver, plug that into the Logitech with 3.5mm cable, and Bluetooth from the tablet to the receiver

Pretty much the same happened to me. There are two wires coming from the wired remote control. One has a green plug which plugs into your sound system (computer sound) and the other connects to the Sub Woofer assembly. Feel this later cable for a harden section. It will probably be closer to the Subwoofer, but may be anywhere along it. This cable will have been cooked by overheating (Playing sound at full volume for over long periods of time.) . You will feel probably a 6" to1' section that is a tad stiffer and the plastic will crumble. You will need to cut a few inches into the normal cable and remove the bad section. Then strip and tin, the cables and connect them individually . Connect (tin, solder and seal them individually: ground to ground, white to white, red to red, blue to blue, green to green, purple to purple). Depending on the electrical tape you use- there will be a thick bulge in the cord, but it should work fine... or you can connect the severed cable to the original source to avoid the bulge ... but I did not want to shorten my remote any more than I had to.

Phone jack on woofer goes into computer tower (should be color coded green) and power cable on woofer plugs into 120VAC. Speaker phone jack plugs into back of woofer. The speaker cable has an on-off switch and volume control as well as a phone jack for your headset.

Phone plug on subwoofer plugs into phone jack on back of tower! Plug and jack are color coded green. If you plug into wrong jack you get no sound or intermittent sound. Also speaker cables have an on-off swith so make sure you are switched "on" or you will not get sound.

Have you gone into your control panel and checked the speaker volume ???

The main reason why the rear speakers are not working because the sound you are playing are not surround sound or a not a stereo sound and check the setting of your speaker. There is an output sound in your speaker but to low because of the set up of your speakers. Try to set it in Hall, Church, or any set up you will notice that there is difference with there volume in every set up.
