Using the Battery Pack
✍
If your computer does not recognize the battery pack, turn off your computer and push and hold the battery off button for three seconds with a thin,
straight object (such as a paper clip). If this does not solve the problem, remove the battery pack and install it once again.
If an extended battery pack is attached to the computer, turn off the computer and remove the extended battery pack. If this does not solve the problem,
push and hold the battery off button for three seconds. If the problem persists, remove both battery packs and install them once again.

For your safety, it is highly recommended that you use genuine Sony rechargeable battery packs and AC adapters that meet the quality assurance
standard, supplied by Sony for your VAIO computer. Some VAIO computers may only function with a genuine Sony battery pack.
