Re: Computer Ac Adapter

Yeah all you need is a universal variable adapter that could match your old adapters power and amp's and then just use the switch to change the polarity

There is no power supply passing into the device. the green led is not at all lit. the volume controller does not show green light. i feel that the power supply is not getting into the device pls help

Get a multimeter and check its output voltage. it must give 11.5V AC as output. The current output in the multimeter must be 1.6 A .If it is not giving the output, your AC Adaptor has gone bad. there are 4 screws on the adaptor which you can open and inside you will find a single step down transformer. of rating 11.5V AC 111600mA(That is 1.6A) Aand 18.4VA rating. You can try to repair it at a transformer rewinding shop(IF HE DOES IT PROPERLY). or, try to get a new AC ADAPTOR OF THE SAME RATING.

Can i use AC Adaptor that has input: 230V-50Hz output: 9VDC to Creative SBS 2.1 370 Speaker?

The Creative SBS 370 Works on 11.5V AC (IT IS NOT DC) 1600mA (Means 1.6 Ampere) and 18.4VA. So, the Power Adaptor which you connect to the power socket behind the woofer is an AC ADAPTOR and NOT A DC ACAPTOR.

How to I install Benwin 3d surround and subwoofer speaker to my PC

I can't find my adapter (12v yamaha-model-yst-m7) , and I would hate to have to trash them. Can you help?


You will be able to buy yourself a multi-adapter at nearly any electrical store near you.

This is a very handy device, as it has numerous adapter heads, and aperages and voltages you can set it to accommodate the specific device. Go to your nearest electrical store, ask an assitant, and you will be sorted.

Best of all, this cost round about $10, so it is cheap as well.

Hope this can be of help.

Kind regards

Seems to be no power to speakers.

Disconnect green speaker jack from computer and see if you get a green power light on speakers. If the speakers indicate they have power, your sound card or circuit is shorting out the speakers. If you still have no power to the speakers when disconnected from computer, then no green light means no power to speakers. Either you’re A.C. adaptor is bad or the speakers are shorted out. You have 2 options:
1) Replace A.C. adaptor.
2) Replace speakers.
If you buy new speakers, make sure that they have their own power source (A.C. adaptor).

Acer apire 3000 a/c adaptor

Why did you have to buy a new adaptor? Did it suddenly stop working or was the problem intermittent?

It's my guess the adaptors are fine - very unlikely all three are bad - It's the connector in the laptop that's the problem - it's loose or was pushed too far in at some point so it can't make a tight connection. A good tech should be able to solder it on the inside. Hopefully, you can return at least one of the adaptors.

Good luck.
