Toshiba Satellite laptops use rechargeable batteries for power when they're not plugged into electrical outlets. This allows you to take and use the laptops anywhere. Rechargeable laptop batteries have a lifespan of one to three years. After this time, the efficiency of a battery may decrease or the battery may die and not charge. However, prior to spending money on a costly replacement battery, you should troubleshoot the battery and power cord to ensure the battery is indeed dead.
Power down the Toshiba Satellite laptop. Unplug the power cord.

Remove the battery from the laptop. A Toshiba battery is located on the bottom of the laptop. Slide the locking mechanism to the right. Hold the mechanism in place with one hand while lifting the battery upward with the other hand. Release the locking mechanism once the battery is removed.
Plug the power cord into the right side of the Toshiba laptop while the battery is removed. Press the "Power" button to turn the laptop on. If the laptop turns on, the power cord is properly working. If the laptop doesn't turn on, ensure the electrical outlet is working by plugging in another device. If the electrical outlet is working but the computer won't turn on, the power cord is dead and needs to be replaced. If the power cord is not properly working, it will not charge the battery. Turn off the laptop and remove the power cord.
Examine the battery. Look for signs of damage, such as corrosion, dents or dings. If you see damage on the battery or battery contacts, replace the battery with a new one.
Clean the laptop battery. Pour a small amount of rubbing alcohol into the rubbing alcohol cap. Dip a cotton swab into the rubbing alcohol. Rub the swab onto the battery contacts, located on the battery and in the battery bay, to remove dust and grime. Dirt can prevent the battery from properly charging, so the battery should be routinely cleaned.
Push the laptop battery back into the battery bay. The battery will snap into place.
Plug the power cord into the side of the laptop. Allow the battery to charge for 8 hours or overnight. Do not use the laptop during this time, as it can slow down the charging process.
Remove the power cord. Press the "Power" button. If the laptop will not turn on, the battery is dead and should be replaced.
