You need to update the BIOS of the computer. Log on to support.dell.com and look for the BIOS updates for your computer.
Once downloaded and saved on the computer run the update and leave the computer to complete the updated. It might restart a couple of times.
This should fix your issue.
First, go to control panel - > Audio devices, then right-click any empty spot on the sound device, and show disabled or disconnected devices. If "Speakers" shows up, right-click and choose set as default (or something similiar). If this does not work, just reinstall your audio drivers. Right-click my computer -> Properties -> Hardware - > Device manager - > Sound, then find the sound cards manufacturer name, and right-click an press uninstall.
Did you check the Device Manager, the audio driver, has it a yellow ? against it or is it OK and enabled? If it is has the MUTE button been ticked?
If it has a yellow ? against the audio driver then the correct audio driver was not installed. Go to the Gateway Support/download page to download the correct XP driver for your model laptop's audio device and install it.
If the sound still doesn't work check Device Manager to see if the driver was installed and working.
You need to set the internal mic as the default input device. To check this Right click on the sound icon next to the time and select Recording properties. In the Recording properties right click on Arrey Microphone and select set as default. If this does not help. Uninstall and reinstall the sound drivers. To uninstall the sound drivers click on start and type DEVICE. Open device manager from the results and then look for sound devices. Click on the Plus sign next to Saound and audio devices. Right click on the SigmaTel entry there and select uninstall. Put a check on remove this driver from the computer. Once done restart the computer and go to support.dell.com and click on Drivers and Downloads. Enter your system service tag and download the Sigmatel audio drivers and install them. Check if the MIC works after the restart. If the Arrey microphone is set as the default and you have uninstalled and resinstalled the drivers and it does not work in MSN try recording with the Windows sound recorder and see if it works there. To open the sound recorder click on start and type SOUND. Open sound recorder from the results. Incase the mic does not record even in the recorder it could be bad or have a loose connection. If in warranty call/chat with the Dell technical support. If the warranty has expired consult a local computer guy.
Download Driver Cleaner Pro v.15 from the link. Also, download, and save on your desktop, a clean version of your Sound Card drivers. Run DCPv1.5 and remove all of your audio drivers, plus any possible problem drivers (i.e., if you installed generic drivers to try and get your card to work). After you uninstall, reboot, install your downloaded drivers and reboot again. This should fix your problem, if not please post an update to this thread and I'll continue troubleshooting with you.
