Update a Mesa 3 Battery for Use in a Mesa 4 Tablet
11 Jun 2024
The Mesa 4 uses the same battery as the Mesa 3 (JSPN 28000). You can use a Mesa 3 battery in a Mesa 4 tablet if you have updated the battery firmware to version 7A. The Mesa 4 cannot recognize a battery with firmware older than version 7A. (The battery that is included with your Mesa 4 will work with no additional battery firmware updating. It comes from the factory with the latest battery firmware.) The battery firmware update must be completed with the battery installed in a Mesa 3 Windows device. You cannot update the battery firmware using a Mesa 4 device.
To update the battery firmware,
- Install the battery you want to update in a Mesa 3 tablet.
- Update the firmware on the Mesa 3, which also updates the battery firmware.
- After the firmware update finishes, verify the battery firmware version.
- Go to the Start menu and select Device Info.
- View the firmware version in Battery Status.
- Close the Device Info app.
- Shut down the Mesa 3. (The red LED must be off.)
- Remove the battery.
The battery can now be used in a Mesa 4 tablet.
