Annoying hum from extension speakers using Fujitsu laptop?
I am using a fujitsu siemens laptop for music, karaoke etc, and when I plug in extension speakers or link to an amplifier there is an annoying hum. This is worse when the graphics are changing and/or the laptop is performing commands.
The built in speakers are fine, and I have tried using a USB soundcard as recommended by PC World to no avail, thus eliminating a fault with the external socket. I have used different leads also.
Anyone with constructive help would be most welcome!
i had the same problem….and the only way you can get rid of the hum is to move the laptop & amp and speakers as far away from eachother as possible… them together causes a lot of electircal interference… and you’ll always have a humm of some sort, as long as u have power running through the wires..it’s extremely difficult to get rid of the hum.
i used 8000W worth of audio power with my laptop, amps and three power supplies. and i had a reli bad hum, and just moving the adio wire either made it better or worse…
u have to get the laptop away from the amp n the amp away from the speakers..try that 
but you can’t get rid of it completely, or at least to my knowlege
hope this helped xx
