What is the condition of the battery? You can get the battery condition by Option-clicking on the battery icon on the menu bar. Any condition other than "Normal" or "Good" means the battery is either wearing out or has a hardware fault.
Have Apple or an Apple Authorized Service Provider examine the laptop to provide you with an estimate for the repair.
