Built-in Camera
What should I do if movie playback shows dropped frames when my computer is running
on the battery?
The battery pack is running out of power. Connect your computer to an AC power source.
What should I do if captured images flicker?
This problem occurs when you use the camera under fluorescent lights due to the mismatch between lighting output
frequency and shutter speed.
To reduce flicker noise, change the direction of the camera or the brightness of camera images. In some software
applications, you can set an appropriate value to one of the camera properties (e.g. light source, flicker, etc.) to eliminate
flicker noise.
Why is the video input from the built-in camera suspended for a few seconds?
The video input may be suspended for a few seconds if:
❑ a shortcut key with the Fn key is used.
❑ the CPU load increases.
This is normal and does not indicate a malfunction.
What should I do if my computer becomes unstable when it enters a power saving mode
while the built-in camera is in use?
If your computer automatically enters Sleep or Hibernate mode, change the corresponding power saving mode setting. To
change the setting, see Using the Power Saving Modes
(page 127) .
