Should the computer fail to function properly, the troubleshooting steps below 
may be followed. 

•  Check AC/vehicle adapter, battery, and the power source. 
•  Minimize the configuration, i.e., remove extra peripherals and devices. 
•  Remove the modules one by one (HDD, CD-ROM, FDD, Battery, etc.).  
•  Remove the software suspected. 
•  Set BIOS fail-safe default. 
•  Re-install operating system and application software. 

If troubleshooting steps are unsuccessful, consult your dealer for service.  If it is 
necessary to send in your computer for repairs, a representative from your 
authorized technical support department will provide you with an RMA#.  Only 
after you have spoken with a technical support representative and received an 
RMA# should you send in your computer.
