Sony VGN-FS840 Battery
Your Sony VGN-FS840 battery allows you to move freely about which gives you the opportunity to use it wherever you fancy. It is OK to buy a battery with more milliamps, as it signifies that the battery can last for a longer period of time on one charge. What is truly important is the actual size of the battery and the connection it has. Not all batteries are the same, be sure to check the physical connection and size and compare it to the one you are going to replace. The more power the battery has, the longer it will last when fully charged.
What signals that my primary battery is almost going bad?
- The laptop does not run longer than one hour while unplugged
- The battery has its case swollen and looks like it will explode
- The unit does not turn on at all when unplugged
