Note:- As a general rule, replace the Top Cap Seal and Piezo Seal whenever they are
removed for servicing.
3 Remove the Expansion FFC if fitted. Ease the FFC out of the case by sliding it backwards
and forwards length-ways and pulling it gently up out of the insertion slot in the SSD
Drawer moulding.
4 Remove the SSD Back. This is clipped onto the SSD Drawer at the top end. To remove it:
a) Remove the two securing screws.
b) Remove the SSD Back by lifting its free end out by about 10mm and then prying the
top left-hand corner away from the SSD Drawer moulding until it becomes unclipped.
Take care not to damage the Lithium Battery Contacts on the FFC.
5 Release the Piezo. The tail that connects the Piezo to the Main Power FFC is quite thin
and can be damaged if not handled correctly. Take care to release the strip of the FFC
attached to the Piezo at the same time that the rest of the Main Power FFC assembly is
eased out of the SSD Drawer.
6 Remove the Fuse Contacts.
The Drawer Assembly is now fully dismantled.
