Solving System Problems   6-5

„

 

System does not maintain date, time, system
configuration information

Replace the battery (see “Battery Replacement” in this
chapter).

„

 

System does not boot from hard drive

The system tries to start from the diskette drive before it
starts from the hard drive. Remove the diskette from the
diskette drive.

Run the Setup Utility and check the Boot parameter
settings to verify that the initial boot parameter is set for
hard drive C and not for a diskette drive.

„

 

System performance appears sluggish

Check that your system is set for optimal operation. See
your operating system documentation.

Check the memory requirements of your software
applications. If required, install additional DIMM
memory.

If you added optional memory, check that you correctly
installed the DIMM memory.

„

 

System did not recognize additional DIMM memory

Be sure that the DIMM is correctly installed and that the
holding clips are locked in place.

„

 

System password forgotten

Clear the password and reset it.
