What should I do if my VAIO computer does not turn on or the power button does not work (the charge indicator light blinks fast)?
Your VAIO computer may not recognize the battery pack.

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