The Computer Locks Up
If the computer does not respond to your keyboard entries, try the
following:
1.
2.
Wait a few seconds. Remember that some operations the
computer performs take longer than others. For example, it
takes the computer much longer to recalculate an entire
spreadsheet than to record one figure. Also, GW-BASIC
programs involving many calculations can take several
minutes, or even hours, to complete.
If the computer remains locked up after you’ve waited a
reasonable amount of time, follow the steps in Chapter 4 to
reset the computer.
Note
Changing
the execution speed while running an application
program could cause the computer to lock up. Always exit
the program you are working on before your change the
execution speed.
Low Battery Problems
If the battery runs low, recharge it according to the instructions in
Chapter 4.
The battery inside the Equity LT-286 should last as long as the
computer does. However, if the battery seems to run low sooner
than it should after being recharged, you can test it by following
these steps:
1. Turn off the computer.
2. Connect the AC adapter to the computer and to an electrical
outlet and let the battery charge for at least 12 hours.
