Question about Dell Latitude E6400 Notebook
I connected a Lipo charger to one of the right side USB ports and it caused a short to ground which has caused all USB ports to stop working. I am also getting an error that the Audio has stopped working. I found that the latitude has this "Precision M2400 IO Circuit Audio Board for UMA Motherboard Integrated Intel Video - D810N" board and it has the USB ports integrated onto it that was shorted. What are the chances that replacing only this board fixes the problem? I thought that it was the mother board but now I'm thinking either this card or both it and the MB need replacing.

SOURCE: memory module
Your motherboard supports 533MHz memory modules, no more. If you put anything higher in, it will work, but only at the speed of 533MHz, so there's not much point in aiming any higher. Just make sure what you're buying is a DDR2 533MHz memory module, and it's best to get them in increments of 2. If you have 4 slots on your motherboard, get another 2x512MB modules of RAM. If you're running Windows Vista, it might be worth considering 2x1GB modules. I think that pretty much covers your question, if you have anything else to ask, feel free to reply.

SOURCE: USB Port Malfunction
There is no power option in XP to shut off a USB port to preserve power so dont worry about that. I would try to use a different USB device such as a USB Flash Drive or printer etc. to test. If the flash drive for instance does not say it is disconnected after 2 minutes, then you know that the problem is with the wireless card. If it does the same thing as the wireless card, then you know that its not the card. I would say it would most likely be a motherboard at that point which becomes a rather expensive problem. Hopefully this helps!

in the Dell BIOS you can disable on-board LAN by going into the BIOS (hitting F2 at the Dell splash screen), scrolling down to Integrated Devices, and then selecting "Network Interface Controller" (keep hitting left/right until "OFF" is selected.)
Save changes and exit.

You will have to take the machine apart somewhat, or at least to the point of being able to disconnect and remove the usb port. Here's a link to the D600 service manual download. It will guide you through the breakdown process.

A105 motherboards are available on EBay
At least one of those looked like an entire bottom plastic assembly.
Unless you are pretty computer savvy, you'll want a computer pro to replace teh motherboard.
