Alienware Area-51 m5750 Technical Reference

Your computer has been fully tested and complies with the system specifications before
shipping. However, incorrect operations and/or mishandling may cause problems.
This chapter provides a reference for identifying and correcting common hardware and
software problems that you may encounter.
When you encounter a problem, you should first try to go through the recommendations
in this chapter. Instead of returning the computer and waiting for repair, you may be
able to easily solve the problems by considering the following scenarios and possible
solutions. If the problem continues, contact your reseller for service information.
Before taking further actions, consider the following suggestions:
• Check to see if the problem persists when all the external devices are removed.
• Check to see that the green light indicator on the AC adapter is lit.
• Check to see the power cord is properly plugged to the wall outlet and to
the computer.
• Check to see the power indicator of the computer is on.
• Check to see if your keyboard is operational by pressing and holding any key.
• Check for any incorrect or loose cable connections. Make sure the latches on the
connectors latch securely onto the receptor end.
• Be sure you have not assigned an incorrect setting on the hardware devices in
the BIOS Setup utility. A faulty setting may cause the system to malfunction. If
you are not sure of the changes you made, try to restore all the settings to factory
defaults.
• Be sure all the device drivers are installed properly. For example, without the
audio driver properly installed, the speakers and microphone will not work.
• If external devices such as USB camera, scanner, and printer do not function
correctly when connected to the system, it is usually a problem with the device,
not your computer. Consult the device’s manufacturer first.
• Some software programs, which have not gone through rigorous coding and
testing, may cause problems during routine use. Consult the software vendor for
problem solving.
• Legacy peripherals are often not plug-and-play capable. You may need to restart
the system with these devices powered up and connected for proper operation..
• After BIOS re-flash, be sure to go to the BIOS SETUP and load DEFAULT SETTING.
• Be sure the Quick Key Lockout Switch on the bottom of the computer is not
engaged; otherwise the quick keys will not work.
