Sony VGN-BX540 Battery
Your Sony VGN-BX540 battery makes your laptop portable so as to work or play anywhere in the house or even outdoors! 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. It is OK to buy a battery with more milliamps, it just means the battery will go further on a single charge. What is important is the actual size of the battery and the connection it has. The larger the battery, the longer you will be able to use the laptop on a single charge.
Major symptoms of a failing battery
- The unit does not turn on when not connected to the charger
- The laptop does not run longer than one hour before it dies
- The laptop battery has its case swollen and looks like it will explode
