Battery Pack
Can my computer enter Hibernate mode while running on battery power? 
Your computer can enter Hibernate mode while running on battery power, but some software programs and peripheral 
devices prevent the system from entering Hibernate mode. If you are using a program that prevents the system from entering 
Hibernate mode, save your data frequently to avoid losing data. See Using Hibernate Mode (page 30) for information on 
how you can manually activate Hibernate mode.
 
Why cant I fully charge my battery pack?
The battery care function is enabled to extend the life of your battery pack on the VAIO Control Center. Check the settings 
on the VAIO Control Center.
 
What should I do if a message appears notifying of either incompatibility or the improper 
installation of the battery pack and my computer then enters Hibernate mode?
❑This problem could be due to the battery pack not being installed properly. To solve this problem, turn off your computer 
and remove the battery pack. Then reinstall the battery pack to the computer. For details, see Installing/Removing the 
Battery Pack (page 20).
❑If the problem persists, it means the installed battery pack is not compatible. Remove the battery pack and contact an 
authorized Sony service/support center. To find the nearest center or agent, see Finding More about Your VAIO 
Computer (page 5).

Built-in Camera
Built-in Camera
Why does the viewfinder show no images or poor-quality images?
❑The built-in camera cannot be shared by more than one software application. Exit the current application before launching 
another. On models with Media Gallery, you cannot use another camera application that uses the built-in camera while 
using the gesture function of Media Gallery.
❑The viewfinder may show some noise, for example horizontal streaks, when you are viewing a rapid-moving object. This 
is normal and does not indicate a malfunction.
❑If the problem persists, restart your computer.
 
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.
 
Why are captured images poor in quality?
❑The images captured under the fluorescent light may show reflections of light.
❑A dark portion in captured images may appear as a noise.
❑The area on and around the built-in camera is dirty. Clean the area. See Care and Maintenance Information (page 114).

Built-in Camera
What should I do if captured images contain dropped frames and audio interruptions?
❑The effect settings on your software application may cause dropped frames. See the help file included with your software 
application for more information.
❑There may be more software applications running than your computer can handle. Exit the applications that you are not 
currently using.
❑This problem may occur while your computer is running on the power saving plan, which reduces the CPU performance. 
See Selecting a Power Plan (page 102) to check the current power plan.
 
What should I do if movie playback shows dropped frames while my computer is running 
on battery power?
The battery pack is running out of power. Connect your computer to an AC outlet.
 
What should I do if captured images flicker?
This problem occurs when you use the camera under fluorescent lights due to a mismatch between the lighting output 
frequency and the 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.
