Disconnect the battery by pulling out its connector from the motherboard.
Remove the 4 Phillips-head screws securing the battery to the laptop’s chassis, then lift the 57Wh battery away from the device.

Caution: Handle the battery and its connector with care to avoid any damage.

More info: The 57Wh battery provides up to 12 hours and 30 minutes of web browsing or 8 hours and 20 minutes of video playback, a commendable performance given the device’s specifications.
