Keyboard
If the keyboard response is poor, something may be trapped under
the keys. Turn the keyboard upside down and shake it; do not
probe between the keys as this may cause further damage.
If you spill something on the keyboard and it stops working:
♦
If the liquid is viscous, unplug the keyboard and call your
supplier or an authorised maintainer.
♦
If the liquid is thin and clear, try unplugging the keyboard,
turning it upside down to let the liquid drain out, and drying
it for at least 24 hours at room temperature. If the keyboard
still won’t work, call your supplier or an authorised maintainer.
Expansion cards
If an expansion card does not work, check that all internal cables are
securely connected, that the card is configured correctly, that its use
of system resources does not conflict another card or motherboard
component, and that legacy resources (if it is an ISA card) are
properly declared in the BIOS Setup utility. Check also that the
software which drives or uses the card is correctly configured.
System BIOS
Use the BIOS Setup utility to ensure that the settings are correct. If
the settings appear to have altered, there may be a fault with the
CMOS battery which may need to be replaced (see the
Motherboard
Features & Upgrades
chapter for instructions).
Diskette drive
If you have problems accessing a diskette, check that it is inserted
correctly, that it has been correctly formatted, that it is not write-
protected, and that the diskette drive controller is enabled. Some
application software also may not allow you to read or write to
diskettes during certain other operations, or until you are about to
exit the program.
