Acer Iconia W510 Unplug the Tablet Battery Prerequisite

Carefully insert your metal pry tool between the back cover and the frame at an angle as shown.

Give the tool a twist to the left to start separating the clips.

Work your way to the corner, prying and twisting to pop the clips as you go.

Insert an opening pick to make sure the clips don't close down again as you round the corner and start working on the right side of the tablet.

Continue as before, prying and twisting to release the catches.

Continue along the top edge as before

Unclip the left side of the tablet.

Back to the bottom side again, this little part by itself is a little finicky to get unclipped, just follow the same procedure as with the first one.

And finally the home stretch between the keyboard/power connector and the right hand guide pin, back to where you started.

The rear cover is removed.

Peel back the tape securing the battery connector.

Grasp the plug by the tabs on either side and pull it straight out from the connector.
