Need help connecting Harmon Kardon Northbridge CA91329 to a Dell Inspirion 530. I have tried and when powered up, I get a high pitched tone out of speakers.

You need to set the device on the aux mode. Connect the cable at aux. Sign at the back of the device

good luck

I would try disconnecting the speakers, then turn it on. If protect still shows with no speakers connected, then it needs to go to the repair shop- Might be a blown power transistor.

I had the same issue, definitely check your cable. if that's good try a different outlet. i had mine in the surge protector when it was making the high pitch sound. when i just went straight to the wall outlet by it self it worked great. hope this helps.

The Dell Dimension 2350 Desktop PC motherboard, has an Intel 845GL motherboard chipset,
mounted to it. (System Information),

http://support.dell.com/support/edocs/systems/dim2350/specs.htm#1101572

Here we see that the Intel 845GL chipset supports processors, with a -> maximum <- Front Side Bus of 400MegaHertz, (FSB = 400MHz max.),

http://en.wikipedia.org/wiki/List_of_intel_chipsets#Pentium_4_chipsets

The Intel Pentium 4 model 530 (3.0GHz. Also has Hyper-threading Technology. HT), operates with a FSB of 800MegaHertz, (FSB = 800MHz),

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_microprocessors#Prescott_.2890.C2.A0nm.29_2

(Scroll down. Pentium 4 HT 530 )

You can't make the Intel 845GL chipset support a processor with an 800MHz FSB.
BIOS update or not, the voltage range will be too low. Therefore the FSB is low. Changing just the Multiplier will not do the trick either.

(BIOS Setup, Advanced Chipset Setup. Doubt the options of changing the FSB, and/or Voltage, and/or Multiplier, is available with that BIOS program))

Note your 3.0GHz processor is operating at 1.5GHz?

Max FSB supported is 400MHz, and your Model 530 needs 800MHz? (For max operation)

Post additional questions in a Comment.

[ Chip and Chipset are shortened terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit

The motherboard chipset technology used for your computer, has a Northbridge chip, and a Southbridge chip.

(Does not apply to motherboards that support the Intel Core i3, Core i5, Core i7, and Core i9 processors )

The Northbridge chip handles the faster capabilities of a computer.
Processor, Ram Memory, and High-speed graphics.

[ The AGP technology, and the PCI-Express technology, is High-speed graphics.
Using a graphics card in a PCI slot, or using Integrated Graphics, is NOT High-speed graphics ]

The Southbridge chip handles the slower capabilities of a computer.
Anything connected to the PCI bus, (Such as a PCI graphics card)
IDE (PATA)
SATA
USB
Ethernet
Audio (Sound)

http://en.wikipedia.org/wiki/File:Motherboard_diagram.svg

[ CPU stands for Central Processing Unit. Another term used is Microprocessor, or Processor for short ]

So it is first up to the Northbridge chip, of the motherboard chipset, whether it will support a certain processor, THEN if a BIOS update will help.

Hi sheawm. You can use your speakers as long they have the mini-plug connector such as ipods, blackberrys, laptops, desktops, etc. so it won´t matter. I hope this helps.

Turn off vista hybrid sleep and hibernation mode. It causes more problems then it helps.

If you go to the Harmon/Kardon website, you can find where to buy replacement parts.

http://www.harmankardon.com/

Select product support on the front page, then go to parts.

Then select your product as Harmaron/Kardon SoundsticksII and select your country.

Hope this helps,

Nathan.

"the PT-AE900U supports a full range of input sources, including DVD and video players, PCs and game machines. An HDMI input provides compatibility with HD digital sources, while component video input terminals deliver full-quality, detailed images from high-end, progressive-scan DVD players. The PC IN terminal can be connected to a game machine or PC. Other terminals include composite and S-video, as well as a serial terminal for connecting a touch panel controller or similar device." You can go to Dell support to either read your manual, but your laptop model's manual is there for the reading. It lists all the outputs. if you have a problem figuring which to use, they will tell you. your manual can be found at http://support.dell.com/support/dsn/dsnsearchresult.aspx?c=us&cs=19&l=en&s=dhs&Query=bWFudWFs&SystemID=INS_PNT_P4_9400&ServiceTag=&contenttype=-1&os=-1&component=-1&lang=-1
You may either have to connect the laptop directly to the Panasonic, or you may be able to connect it through the Harmon Kardon, but I doubt if there will be any advantage to doing that.
