Sony VGN-CR290E Battery
Your Sony VGN-CR290E battery makes your laptop portable so as to work or play wherever you fancy. Because no battery is the same, be sure to check the physical connection and size and compare it to the old one. The more power the battery has, the longer you will be able to use the laptop when fully charged. 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 actual size of the battery and the connection it has.
Warnings of a dying battery
- The Sony laptop is unable to boot up when it is unplugged
- The battery gets puffy and looking like it is going to burst
- The laptop does not last longer than 45 minutes while using the battery only
