Problem Cause and action
The computer locks or
does not accept any
input.
Your computer might lock when it enters standby mode during a communication
operation. Disable the standby timer when you are working on the network.
To turn off the computer, press and hold the power switch for 4 seconds or more.
The computer does not
turn off with the power
switch.
If the standby indicator is on and you are working under battery power, replace
the battery with a fully charged one or change your power source to ac power.
If you still have a problem, press and hold the power switch for 4 seconds or
more; this forces the computer to turn off.
The computer does not
start from a diskette.
Make sure that the startup sequence in the BIOS Utility is set so that the com-
puter starts up from the diskette drive (see Online User's Guide for more details).
