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 22) .
❑ If the problem persists after performing the above, it means the installed battery pack is not compatible. Remove the
battery pack and contact an authorized Sony Service Center. To find the nearest center or agent, see Finding More
about Your VAIO Computer
(page 5) .
Why does the System Properties window display a slower CPU speed than the
maximum?
This is normal. Because your computer's CPU utilizes a type of CPU speed controlling technology for power conservation
purposes, System Properties may display the current CPU speed instead of the maximum speed.
What should I do if my computer does not accept my password and returns a message,
Enter Onetime Password?
If you enter a wrong power-on password three times consecutively, the Enter Onetime Password message appears and
Windows will not start. Press and hold the power button for more than four seconds to check that the power indicator light
turns off. Wait for 10 or 15 seconds, then restart your computer and enter the correct password. When entering the password,
check that the Num lock and Caps lock indicator lights are unlit. If both or either of the lights is lit, press the Num Lk (or Num
Lock) key or the Caps Lock key to turn off the indicator light before entering the password.
