Solution
Consult the manufacturer of the adapter for help. Be sure
that the memory card is one of the supported types:
CompactFlash (1, 2, and Microdrive), Memory Stick,
MultiMedia, Secure Digital, or SmartMedia memory cards.
Make sure that the memory card is fully inserted into the slot.
Shine a flashlight into the empty card slots. Check whether
any pins inside are bent. Disconnect the computer from
power and straighten the bent pins with the end of a
mechanical pencil. If a pin has bent to the point where it is
touching another pin, replace the memory card reader or
have the computer serviced.
Solution
Turn on the monitor and check that the monitor light is on.
Try a different monitor.
Check the cable connection from the monitor to the computer
and to the electrical outlet.
Press any key or click the mouse button and, if set, type your
password.
Be sure that the monitor can accept the same horizontal
scan rate as the resolution chosen.
Press the power button to resume from Standby mode.
CAUTION: When attempting to resume from standby
mode, do not hold down the power button for more than four
seconds. Otherwise, the computer will shut down and you
will lose any unsaved data.
Check that the monitor is plugged into an active connector
on the rear of the computer.
Solution
Restore the monitor settings to factory default.
