Troubleshooting 7-3
System emits continuous beeps.
Turn the system off, wait at least five seconds, and turn the system on. If
the beeps continue, call the NEC CSD Technical Support Center.
System does not maintain date, time, system configuration
information.
Change the battery (see “Battery Replacement” in Section 3,
“Disassembly and Reassembly”).
System does not boot from hard drive.
The system usually 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 (see Section 2, “System Configuration”) and set the
initial Boot parameter to Hard Drive instead of Removable Device.
System does not boot immediately after hard drive spins up.
The “Hard Disk Pre-Delay” in the BIOS Setup utility can be changed to a
lower setting. (If a message “operating system not found” appears after
changing the setting, the delay is set too low. Set the hard disk pre-delay
slightly higher.)
System performance appears sluggish.
Check that the system is set for optimal operation. See the operating
system documentation.
Check the memory requirements of the software applications. If required,
install additional DIMM memory.
If optional DIMM memory was added, check that it is correctly installed.
System password forgotten.
Clear the password and reset it. See “Clearing the CMOS and Password”
in Section 4, “System Board.”
Microsoft Windows does not recognize the Pentium III processor
Windows incorrectly identifies the Pentium III processor as a Pentium II
or Pentium Pro on the General tab of the Windows System Properties
sheet. This does not effect in any way the performance of the Pentium III
processor. The system BIOS correctly detects the Pentium III processor at
startup. A patch can be obtained to fix the identification in the General
tab. Check for the patch at Microsoft’s website (www.microsoft.com) or
the NEC CSD website (www.nec-computers.com).
