Realtek Hd Audio Drivers - Dell Latitude 3300 Owner's Manual

• Press down on the palm rest on first the left side of the touch pad and then the right. See if the cursor starts moving on its own.
• Run ePSA Diagnostics and try to recreate the problems there. If either of these situations occurs, replace the palm rest.
No Pointer Movement
No pointer movement from the touch pad (or track stick, if available) usually is the result of one of two things: The touch pad has been
disabled in the driver interface, or the touch pad cable is damaged or disconnected. Follow the steps below to determine the problem.
1 Connect an external mouse - In either situation, an external mouse should still function. If it does not, try booting into Safe Mode and
testing both devices again.
2 Enable the touch pad in the driver settings - Using the external mouse (or key strokes if no mouse is available), go into the Dell
Touchpad Properties. Go to the Device Select section and enable the touch pad. If already enabled, get the latest driver from Dell
support site.
3 Test the device in Dell ePSA Diagnostics - To eliminate a potential software problem, run the Dell ePSA Diagnostics and test the
device here.
4 Check for mechanical problems - As a last resort, press down on the palm rest where the touch pad connector is located on the
system board. If the pointer reacts in some way, then the cable may just need to be reseated. Otherwise, replace the palm rest.

Troubleshooting audio issues
This topics details the troubleshooting steps in resolving audio related issues specific to IDT92HD87 audio chip
No Audio
Determine if the problem is only on the internal or external speakers or both.
1 If the problem is external only, try reseating the speakers or headphones. Also try another set of speakers or headphones if available.
Check the speaker connector for damage. If the problem does not happen with different speakers, then the problem is related to the
external device. If it persists, then there is a problem with either the audio connector or the audio controller. Confirm this by running
Dell Diagnostics.
2 If the problem is internal only, try shaking the unit and see if the sound returns or plays intermittently. If it does, then a connection for
the speakers is loose and the unit needs service. If there is still no sound at all, then try deleting the hardware profile (if possible) and
recreating it. Test the speakers using Dell Diagnostics both internally and externally. If the problem only happens on the internal
speakers, then the speakers and possibly the system board need to be replaced.
If there is no audio from either internal or external speakers, then check the following:
1 Adjust the volume controls. Some systems also have an external volume control in addition to the one in the Windows® operating
system.
2 Check Device Manager and ensure the audio driver is installed correctly. Any problems indicated here can normally be resolved by
reinstalling the audio driver from the ResourceDVD or from dell.com/support.
3 If the audio is installed correctly in Windows but there still is no sound, run Dell Diagnostics on the audio controller. If these fail or no
sound is heard, then replace the system board. If audio does play during this test, then the problem is most likely software related.
