Editing Psion Series 3c Hinge Repair (section)

== SSD doors on the way in ==

'''Open both SSD doors before lifting the mainboard.'''

On the 3c the doors are sensed by '''PCB tracks and a small metal connector on the door hinge''' rather than by microswitches, so you are not at risk of the [[Psion Series 3mx|3mx]]'s snapped-switch fault — but the contact is still delicate and the habit is worth keeping.<ref name="rc3mx">Richard Zealley, [https://www.retrocoding.uk/psion-3mx-ssd-microswitch-repair/ "Psion Series 3mx SSD door microswitch repair"], Retro Coding, 25 May 2020.

While the machine is open, '''clean those tracks and the metal contact''' — it costs nothing and cures a lot of intermittent SSD faults.
