What should I do if a message appears indicating that the battery pack is incompatible or has been incorrectly installed, after which my VAIO computer enters Hibernate mode?

• A battery error may have occurred.
  Push and hold the battery off button on the bottom of your VAIO computer for about three seconds with a thin, straight object (such as a paper clip). [Details]

• This problem could be due to the battery pack not being installed properly.
  To solve this problem, turn off your VAIO computer, remove the battery pack, and then reinstall it. [Details]

• If the problem persists, it is likely that the installed battery pack is not compatible with your VAIO computer or has failed. Turn off the computer, remove the battery pack, and then replace it with a new one specified by Sony.
