Sony VGN-AW390 Battery
Your Sony VGN-AW390 battery makes your laptop portable which gives you the opportunity to use it where you want. More amps in a battery basically means the longer you will be able to use the laptop on a single charge. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the old one. Buying a battery with a higher milliamp rating is fine, as it signifies that the battery can last for a longer period of time on one charge. What really is critical to a battery fitting your laptop is the physical size of the battery as well as the connection.
Major symptoms of a faulty Sony battery
- The laptop does not last longer than 45 minutes before it dies
- The battery has its case swollen like its about to burst
- The unit is unable to boot up when it is not plugged in
