Gateway 400SD4 Battery
Your Gateway 400SD4 battery makes your laptop portable which gives you the opportunity to use it inside, outside or anywhere your heart desires. Not all batteries are the same, make sure and double-check the part number of the new battery and compare it to the old battery. Buying a battery with a higher milliamp rating is fine, as it just means the battery will last longer. What is truly important is the physical size of the battery as well as the connection. The more power the battery has, the longer it will last on one charge.
Major clues the primary battery is in need of replacing
- The battery has its case swollen and looks like it will explode
- The Gateway laptop refuses to turn on while not connected to the AC adapter
- The laptop does not last longer than 45 minutes before it shuts itself down
