What is the soak test?
WARNING: INITIATING THE SOAK TEST WILL CAUSE THE LOSS OF USER DEFINED GROUPS AND USER INSTALLED SOFTWARE!!! It has long been known in the computer and electronics industries that electrical components, for the most part, fail either shortly after they are first activated or after many years of service. Because of this fact the concept of the soak test or burn-in or life test was invented. Simply put, the machine (in this case a computer) is put through a repetitive testing loop for several hours (24 for the Psions to be more precise). This procedure would then filter out most of the bad batches and prevent them from reaching the hands of the general consumers. To activate the soak test on the Psion series 3, press (See warning at the beginning of this section) Control-Shift-Psion-K on the System screen. This procedure will cause a soft-reset of your Psion.
