How do i hookup logitech speakers #z313 to my emachine e202hl

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

There should be a volume level adjustment on the speakers.

Verify the master volume on the computer is turned up as well as the volume of the app in use is turned up.

Your new moniter may not be compatible with your computer. I have an Emachines that won't take a flat screen. I have to use a big bulky moniter because it says not connected even thought the hookup fits the back of the tower. That might be your problem. Did your old moniter work correctly?

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 ???
Start, Control Panel, Sound

can you give more info if there is any sounds comming from the tower

plug these speakers
if your computer came with a motherboard disk the sound drivers could be on it
control panel sounds and audio,volume,advanced,speakers select appropriate speakers or
audio you will find 3 drop down lists make the necessary adjustments there or
control panel,administrive tools,computer management,device manager,sound video and game controllers could be a yellow question mark? right click to re-install drivers
hope this helps
