There are two screws holding the back panel in place. They are located below the two rubber pads at the back of the pc. They must be removed in order to open the back panel.

Just gone through this, but two problems surfaced. 1 it won’t connect to our usual WiFi router and can’t figure out why. Is it possible to damage the WiFi connectivity when removing battery? 2 there’s no indication of charge levels. It says 100% and doesn’t change. Thoughts?

Take all that back. Went back in and battery connector hadn’t clicked in far enough. Seems to be working fine now.
