I am using sony vaio laptop for 2 years, from last one year it doesn't work if charger is not connected to it. it shows battery status as excellent with green light but there seems some issue of connection between battery and laptop.

If laptop shuts down instantly after removing the adapter, then it could be that DC/DC converter that takes power from the battery and converts its voltage to the suitable one for powering the laptop is failed.
