Diagnosis during operation
●
Look for blinking LEDs on the side of the computer. The blinking lights are error codes that will
help you diagnose the problem. Refer to the
Diagnostic LED and audible (beep) codes
on page 92 section of this document for information on interpreting diagnostic lights and
audible codes.
●
Check all cables for loose or incorrect connections.
●
Wake the computer by pressing any key on the keyboard or the power button. If the system
remains in suspend mode, shut down the system by pressing and holding the power button for
at least four seconds, then press the power button again to restart the system. If the system
does not shut down, unplug the power cord, wait a few seconds, then plug it in again. If it does
not restart, press the power button to start the computer.
●
Reconfigure the computer after installing a non–plug and play expansion board or other option.
●
Be sure that all required device drivers have been installed. For example, if you have connected
a printer, you must install a printer driver.
●
If you are working on a network, plug another computer with a different cable into the network
connection. There might be a problem with the network plug or cable.
●
If you recently added new hardware, remove the hardware and verify if the computer functions
properly.
●
If you recently installed new software, uninstall the software and verify if the computer functions
properly.
●
If the screen is blank, plug the monitor into a different video port on the computer if one is
available. Alternatively, replace the monitor with a monitor that you know is working properly.
●
Upgrade the BIOS. A new release of the BIOS might have been released that supports new
features or fixes your problem.
●
Press the caps lock key. If the caps lock LED toggles on or off, the keyboard is operating
correctly.
