system board. To reduce the risk of system board or component damage, always disconnect the power cord
from the power source before opening the computer.
If you encounter problems with the computer, monitor, or software, see the following list of general
suggestions before taking further action:
●
Be sure that the computer and monitor are plugged into a working electrical outlet.
●
Check to see that the voltage select switch (some models) is set to the appropriate voltage for your
region (115 V or 230 V).
●
Check to see that the computer is on (the power light is on).
●
Check to see that the monitor is on (the monitor light is on).
●
Turn up the brightness and contrast controls of the monitor if the monitor is dim.
●
If the system does not boot, press and hold any key. If the system beeps, then the keyboard is operating
correctly.
●
Check all cable connections for loose connections or incorrect connections.
