Sony VGN-FW378J Battery
Your Sony VGN-FW378J battery makes your laptop portable which gives you the opportunity to use it where you want. Because no battery is the same, make sure and double-check the size and model number in order to make sure it is similar to the one you are going to replace. The more power the battery has, the longer it will last on a single charge. It is OK to buy a battery with more milliamps, as it suggests the battery will last a bit longer 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.
What symptoms are present when the primary battery is in need of a replacement?
- The laptop does not turn on when it is unplugged
- The laptop battery gets puffy and looks like it will explode
- The laptop does not last longer than 45 minutes while unplugged
