Avoiding Standby While Using Infrared - HP Compaq NX7000 Reference Manual

Communications
Shield the ports from direct sunlight, flashing incandescent
light, and fluorescent light.
Be sure that signals from a remote control or other wireless
device (such as a cell phone, a headset, or an audio device)
do not aim at either port.
During the transmission, do not move either device and
do not allow objects or movement to disrupt the beam.

Avoiding Standby While Using Infrared

Standby is not compatible with infrared transmission. If the
notebook is in Standby, an infrared transmission cannot be
initiated.
If Standby initiates during an infrared transmission, the
transmission stops. To resume from Standby, briefly press
the power button. The transmission resumes when the notebook
resumes from Standby.
