replaced.

NOTE: Connecting the computer to a live AC

outlet prolongs the life of the RTC battery.

First, reset the date and time under Control

Panel (Computer Setup can also be used to

update the RTC date and time). If the problem

persists, replace the RTC battery. See the

Hardware Reference Guide for instructions on

installing a new battery, or contact an authorized

dealer or reseller for RTC battery replacement.

in Computer Setup.

Cause

Solution

Processor is hot. 1. Make sure airflow to the computer is not

blocked. Leave a 10.2-cm (4-inch) clearance

on all vented sides of the computer and above

the monitor to permit the required airflow.

2. Make sure fans are connected and working

properly (some fans only operate when

needed).

3. Make sure the processor heatsink is installed

properly.

Hard drive is full. Transfer data from the hard drive to create more

space on the hard drive.
