Don't switch off notebook, hibernate or sleep, which stores intermediate progress to disk or keeps it in memory. Notebooks have a configuration you can set to do this automatically when closing lid.

The reason cep2 returns to zero is because it has very long job intervals before it saves progress. In between is prohibitive because the job would constantly save 1-2 gigabyte to storage causing you to have a hiccup experience while using. This project is really targeted at devices that are on large parts or all day, desktops, but if you use the hibernate/sleep functionality, no reason to not run these. One at the time is recommended for notes.

Laim, 'leave application in memory when suspended' on or off, is completely irrelevant to the resuming of the task after hibernation or sleep from where it left off. Hibernation and sleep simply write a copy of memory/ram+vm to storage respectively keeps the memory under power, so the computer basically continues where it was after powering up again. Personally do not favor sleep as when there is a power blip you loose what was in memory.

Laim is relevant to interrupting a task so that another can compute, such as the agent may do autonomously during prioritization conflicts. This function is recommended for the cep project as standard to be switched on. This will -not- protect against power off / boot cycles. Then the task will always skip back to the last checkpoint save the program has made.
