„
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 Boot 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 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 (see Section 3, “Disassembly and
Reassembly”).
If optional DIMM memory was added, check that it is correctly installed.
„
System password forgotten.
Clear the password and reset it. See “Clearing a Password” in Section 2,
“System Configuration.”
