Troubleshooting
What should I do if a message window, notifying of incompatibility or improper installation
of the battery pack, appears and my computer enters Hibernate mode?
❑ This issue could be due to the battery pack not being installed properly. To resolve this issue, turn off your computer and
remove the battery pack. Then install the battery pack to the computer again. For details, see Installing the Battery Pack
(page 24).
❑ If the issue 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 Sony Support Information
(page 205).
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 CPU's current speed instead of the maximum speed.
What should I do if Windows does not start, showing a message, when I start my
computer?
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 goes
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 indicator and Caps lock indicator are off. If any are lit, press the Num Lk (or Num Lock) key or the
Caps Lock key to turn off the indicator before entering the password.
