Checking the Basics
To solve some basic system problems, follow these steps:
Step 1 Was an alert message issued by the system software?
Yes. Check the component named in the alert message.
No. Go to Step 2.
Step 2 Visually inspect the chassis. Is the system wet or damaged?
Yes. Liquid spills, splashes, and excessive humidity can cause damage to the
system. If an external device such as an external drive gets wet, contact your
service representative for instructions. (See the “Obtaining Technical Assistance”
section on page xviii.)
