Like any electronic product with a rechargeable battery, your laptop could use an update with a simple battery swap. Your laptop battery can be fully recharged about 1,000 times; that means when your battery is drained, it can be recharged back to full power. Sometimes that can be every few days or every few weeks. Look in your computer preferences to see your “cycle count” of how many times your computer has charged. If it’s over 1,000, take it to a service center and have your battery replaced. It’ll improve functionality of your computer, and the store will be sure to recycle your old battery.
