The positions to drill mentioned in my last post follow:
8mm towards the front of the keyboard from the centre of each of the small round feet.
Draw a line connecting these two holes. Measure 60mm and a further 105mm from the hole nearest the on/off switch and 8mm forward and back at each of these points.
Try a 1-2mm drill so you can see where the screw is before drilling a bigger hole. The support that the screws screw into is 3mm in diameter so if you use a 3mm (1/8inch) drill you should disconnect the support from the cover. all that will be left is a rib running front to back.
Take this slowly.
Hi, there are 6 screws and 2 clips holding the cover over the main circuit pcb. You can lever the cover away from the main part of the keyboard and break the supports for the screws and probably break at least one of the clips. OR you could try drilling out the screws and save the clips. You will need to be accurate with the drilling or you will damage the wires to the battery possibly causing FIRE! Alternately leave these two for breaking off. You can effect required repairs and refix the pcb and cover to the main part of the keyboard with double sided tape or your preferred alternative.
One other hint, when replacing the striplines connect the trackpad (small) one first as the larger one is much easier to fit second than the other way around.
Do not attempt to open the keyboard from the top as super glue and disaster lurk on that path.
