Troubleshooting

This chapter shows you how to deal with common system problems. 
Read it before calling a technician if a problem occurs. Solutions to more 
serious problems require opening up the computer. Do not attempt to open 
the computer yourself; contact your dealer or authorized service center 
for assistance.
