Troubleshooting 8-3
„
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 “CMOS Battery Removal” 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 “Delay for HDD” in the CMOS Setup Utility “BIOS Features Setup”
menu can be changed to a lower setting. (If a message “operating system
not found” appears after changing the setting, the delay is at too low. Set
the 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 (see Section 3, “Disassembly and
Reassembly”).
If optional DIMM memory was added, check that it is correctly installed.
„
System does not boot after processor was replaced.
If the system does not boot (as might be the case if you are replacing one
processor with a slower one), press the power button a second time.
If the system still does not boot, clear CMOS (see “Clearing CMOS” in
Section 2).
