Sony VGN-Z790Y Battery
Your Sony VGN-Z790Y battery allows you to move freely about so that you can use it wherever you fancy. The larger the battery, the longer you will be able to use the laptop when fully charged. Because no battery is the same, make sure and double-check the part number of the new battery and compare it to the old battery. Buying a battery with a higher milliamp rating is fine, it just means the battery will go further on a single charge. What is truly important is the physical size of the battery as well as the connection.
Important signs the primary battery is going out
- The laptop lasts under 20 minutes before it shuts itself down
- The laptop battery has its case swollen like its about to burst
- The Sony laptop is unable to boot up when not connected to the charger
