Editing Psion Revo Troubleshooting Guide (section)

== Step 2: the case microswitch ==

'''A microswitch on the rear switches the Revo on and off as the case is opened and closed.''' It is '''easily broken by too much force when refitting the battery bay''' — which means it is very often broken on a machine that has already been opened once.<ref name="r3uk" />

| '''Does not wake on opening, or does not sleep on closing''' || Broken or displaced case microswitch. Frequently the legacy of a previous battery replacement.<ref name="r3uk" />
|-
| '''Machine will not open or close properly after a repair''' || '''The battery pack is not seated correctly.''' Check this before suspecting the hinges.<ref name="r3uk" />
