The total watts is 30W RMS... watts = volts x amps Using 240v ac gives: 30=240xamps Amps=30/240 = 0.125 amp or 125 ma. Short answer is disassemble to check the wiring on the transformer.... a wire may be disconnected. Check using a voltmeter the input to the transformer and the output (if any). You have to do a bit of simple fault finding I afraid.

I need the driver for it, i have no sound


Anonymous,
There are no drivers for the A425 speakers. Make sure the power cable is attached to the speakers as well as the speakers plugged into the correct jacks. If your speakers are plugged in and powered on and u still have no sound; check to make sure the sound card drivers are installed.
Thank You,

Dell a425 disassembly


I found this URL for you that shows a Dell forum where you could probably get all the info you need. It also has specifications for all the internals should you need to replace something. Good luck and be safe. I learned to hate capacitors a long time ago. :-) http://support.dell.com/support/topics/global.aspx/support/kcs/document?c=us&l=en&s=gen&docid=DSN_E876EF53BCA3F058E030030ABD6260B2&isLegacy=true

My subwoofer and speakers wont draw power when i plug it in, could it be the fuse or something else?


The Altec Lansing A425 doesn't appear to have a fuse. Check for a circuit breaker on any surge protectors it might be plugged in to and make sure they haven't been tripped. Confirm that the power cord is firmly plugged in. Additionally, you could check the wall transformer with a multimeter to make sure it is providing the correct voltage needed by the speakers. Check the back of the subwoofer for a hidden power switch. If everything is plugged in and turned on, but you still don't have power, you will either need to open the device up and troubleshoot it or replace it.
