Toshiba - interfering with external speakers power adapter laptop

Hello

I'm new here, I have a Toshiba laptop and I want to play music through my SOUND system. I connect one of my headphones, entrance through my itunes mixer - and - play, backing tracks, etc.

The only problem is when the adapter is plugged, it creates massive noises in my speakers, but when it is unplugged, IE, running on battery only, it's fine.

Do I need a new adapter and batteries or there at - it another way to solve this problem? And a new adapter solve the problem?

Thank you for your help in advance

Hello

It could be a ground loop. I'm don't know if this will help, but maybe the pre-amplifier might help.

    Hello Michael,

    There is a power button to render the sounds that are a hardware mute button. It seems that it is on, mute the sound at the level of the material, which is different from the mute of software that comes with the Windows sound Properties dialog box.

    Locate the mute button on the laptop (on Dell its usually on the top left row, near the display) to activate the sound at the hardware level, then check that your audio software is assigned to the properties through the external speakers.

    Let me know how you fare.

  • Load a X 220 with a T530 power adapter?

    I have a 220 X (which is, hands down, the best laptop I've ever owned). My wife recently bought a T530 for herself. Power adapters seem to have about the same thing, if the T530 has a much larger brick. Are the two compatible adapters, or if I'm out of power with only its adapter available would it FRY my machine?

    You can use a 65, 90 and 135 Watt with the 220 X adapter. T530, you've got have a 90 Watt adapter. The adapter is designed to provide only the current (voltage is fixed) and therefore the power only if required by the machine. It does not constantly 65, 90 or 135 watts, the maximum power.

  • Qosmio G10 - no sound with external speakers

    When I connect external speakers, no sound coming from them, on the built-in speakers. Could this be a hardware problem?
    Thanks for your help.

    Hello

    You didn't explain what happening exactly when you put the audio in Audio out port Jack. Now integrated speakers shouldn't be active any more. If they still work, I guess this little mixer of audio port which allows to switch between internal and external stakeholders can be damaged.

    If there is any attempt of trying to connect headphones or external speakers to make sure that no sound is at all.

  • The A7r will work with only the power adapter plugged

    I want to use this camera (once I have purchaced one) to copy photos and slides.  There may be a lot of time involved, and it would be nice not having to worry about battery life.

    Hello oldchas! AC adapter / CC of the A7R is not able to provide a continuous camera power while it is operating. Only a charged battery can power the device. Power must be turned off and the camera connected to the AC adapter to charge the battery. The battery is not charged if the switch is on when you are connected to the power adapter.
