Acer 3000 User Manual page 59

I want to eject the optical drive tray without turning on the
power. I cannot eject the optical drive tray.
There is a mechanical eject button on the optical drive. Simply insert
the tip of a pen or paperclip and push to eject the tray.
The keyboard does not respond.
Try attaching an external keyboard to a USB 2.0 port on the computer.
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 metre 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.
