The DC jack soldered to this board. The laptop is working great, but no sound. How do we get to the jack to replace it? Test the laptop with each memory module separately. Even though this laptop has a separate audio board, I believe the audio chip located on the motherboard.

This cable is plugged into connectors on the motherboard on both ends. I have tried to remove the case on the bottom and I have removed the wireless card, the hard drive, the battery and everything I can find, but there is still something holding it together in the area of the fan? Start separating the top cover assembly from the bottom assembly.

Try the chipset driver for Vista x64, which should also install the drivers for the wired NIC. Or if i wait for even half an hour it doesn nothing.

Mine will be forthcoming asap. You can use either one.
