Sony VGN-FJ290P Battery
Your Sony VGN-FJ290P battery makes your laptop portable which gives you the opportunity to use it wherever you fancy. The larger the battery, the longer you will be able to use the laptop on one charge. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the one you are going to replace. Getting a battery with a higher amp rating is OK, it simply means it is a stronger battery. What is important is the actual size of the battery and the connection it has.
Key symptoms of a defective primary battery
- The battery has its case swollen and looking like it is going to burst
- The Sony laptop will not turn on when not connected to the charger
- The laptop lasts under 20 minutes while unplugged
