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?

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

• If the problem persists, it is likely the installed battery pack cannot be used with your VAIO computer, or may have failed. Turn off the computer, remove the battery pack and replace it with a new one specified by Sony.
