  - The battery pack may not be installed properly.

    Remove the battery pack and reinstall it properly. To install or remove the battery pack, see Installing the Battery Pack (SVF143/SVF153) or Removing the Battery Pack (SVF143/SVF153).

  - If the problem persists, it means the installed battery is not compatible with your VAIO computer.

    In this case, push and hold the battery off button for three to five seconds with a thin, straight object (such as a paper clip).

    If the problem persists, contact an authorized Sony service/support center and replace the battery pack with a new one specified by Sony.
