The CD or DVD drive cannot access a disc.
Check the following:
•
Make sure the disc is supported by the drive. If your computer 
connects to a CD-ROM drive, it can read CDs but cannot read 
DVDs. If your computer has a DVD drive, it can read DVDs in 
addition to CDs.
•
When placing the CD or DVD in the drive tray, make sure it is 
secure in the spindle on the drive tray.
•
Make sure the CD or DVD is free from scratches or smudges. If the 
CD or DVD is dirty, clean it using a disc cleaning kit. Remember to 
follow the instructions included with the kit.
•
If the problem does not lie with the disc, your CD or DVD drive 
may be dirty. Clean it using a drive cleaning kit. Follow the 
instructions included with the kit.
The keyboard does not respond.
Try attaching an external keyboard to the USB connector on the 
computer’s rear. If it works, contact your dealer or an authorized 
service center as the internal keyboard cable may be loose.
The infrared port does not work.
Check the following:
•
Make sure that the infrared ports of the two devices are facing 
each other (+/- 15 degrees) a maximum of 1 meter apart.
•
Make sure there is a clear path between the two infrared ports. 
Nothing should be blocking the ports.
•
Make sure you have the appropriate software running on both 
devices (for file transfers) or you have the appropriate drivers (for 
printing to an infrared printer).
•
During the POST, press F2 to access the BIOS Utility and verify that 
the infrared port is enabled.
•
Make sure both devices are IrDA-compliant.
