    I tried to follow the steps that was listed as the solution. Truth, I didn't understand them. I have the ACS45.2 speaker system and don't know what to do.

  • Helplessblde Feb 13, 2008

    Wanted to expand on the problem. There are two volume buttons (up & down) and a power light on top of the main speaker. When you push both together, the power should turn on and off and when on you should be able to adjust the volume. The power button is on continuously (won't turn off) and the volume will not adjust. There is also a subwoofer, although that has it's own volume and seems to work. ANY help would be greatly appreciated.

    I have a similar problem with the Altec Lansing acs45.1. The down button to decrease the volume no longer functions, only the button to increase the volume. And I can't power the unit down since both buttons need to be pressed simultaneously to accomplish this. I opened up the speaker and everything looks ok. I've read on another forum that it might be the Electronic Volume Controller IC (PT2256) but I don't know how to check if mine is good and I haven't found a source for one anyway.

    the problem is in the board your volume control is defective. Just replace volume control IC PT2256 and it will be ok.

    the problem is on the circuit board your volume control is defective. Just replace PT2256 your volume control IC and it works fine.

Double check your connections. Still not working fine. Remove the input jack connector and try to touch or hold the tip of the connector, also adjust the volume of the speaker, you should heard loudly the 60 hertz sound of your body signal. Otherwise you have a defective amplifier in the speaker system.

Press and hold the "Fn," or function, key on your EEE PC-1000's keyboard.

Press "F3" while holding "Fn" to lower the brightness on your monitor.

The brightness on your computer decreases each time "F3" is pressed.

Press "F4" while holding "Fn" to increase the brightness on your monitor.

Each time "F4" is pressed, the brightness increases.

Press "F8" while holding "Fn" to decrease the volume from your EEE PC's speakers.

Each time "F8" is pressed, the volume decreases.

Press "F9" while holding "Fn" to increase the volume from your EEE PC's speakers.

Each time "F9" is pressed, the volume increases.

Press the "Ins" key while holding "Fn" to take a screen shot, or make a copy of what is currently on the computer screen.

How do I increase the volume on my Nokia 1661?

There are 2 types of volume in your nokia phone that you can increase or decrease.

The first one is the ring tone volume. You can either increase or decrease your ring tone volume by pressing the menu key then go to settings, go to profile, select any desired profile go to personalise go to ringing volume, then increase or decrease by using the navigation button to the right or left.

The second way is to increase or decrease the volume of the speaker of your phone which i think is the cause of your question (this volume enables you to hear clear and loud the person on the other phone). You increase or decrease the volume by making a call, as soon as the call starts ringing, press the navigation key to right to increase the volume or to the left to decrease the volume.
