    Dead laptop batteries are easily replaced, and trying to revive them is not cost-effective. If your battery is not charging anymore, it is just not a good battery, and you need to get a new one.

    Leaving your laptop plugged in all the time isn't always the greatest idea. You want to unplug the power adapter occasionally and let the battery run down to almost zero, and then recharge it. That helps the battery last a lot longer than if you keep it attached to the power adapter all the time. The battery is supposed to be used to power the equipment. If you have the power adapter plugged in all the time, the battery is not being used.
