    The process took me about 30 minutes. If I were to have to do it again then I could probably do it in 10 minutes now that I know what is involved!

    I lift more than the last photo shows. Dark rubber with plots, visible on photo are blocking the opening.

    This was a bit more fiddly than expected given the speaker arms are stuck to the battery

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.

The bottom of the pictured device may feature Phillips #00 screws, but I also have this laptop and the screws around the edge of the bottom panel are Torx T5s on my device.

Same here, they are really small Torx on my Asus UX303U!
