markop619, CEP2 is a special "opt-in" project that is this way due to it having special requirements - most notably, very long intervals between checkpoints (unfortunately, there is no way around this). Indeed, depending on your hardware, this could be 5, 6 or even 7 hours in length, during which, if you switch your machine off, no checkpoint will be made - thus, starting that phase of the procedure all over again.

One option that could circumvent this scenario from happening, is to use the Hibernate option to shut/move your computer as well as ensuring that you've got the box "Leave applications in memory while suspended" ticked.

Either de-select CEP or leave your PC running 27/7, it is the only way with these WUs I find

markop619, Hibernate is very similar to actually shutting your computer off (in a controlled manner) - except, an image of what was in it's memory is stored to disc, so that, when it's restarted again, everything is simply reloaded from disc (and hence, a lot quicker to restart). This could be used (as I did when I was moving my machine between home and work) when your machine is going to be in transit.

If you can leave your computer on 24/7, then that, as Scribe has alluded to, is the best way to run these particular WU's.

Thanks guys, I will leave my computer to work 24/7. Does anyone from you do like that?

Hello markop619,
The first checkpoint takes only a few minutes to reach. The second (or maybe third) checkpoint might take 4 hours. So you may have other problems. Make sure that your profile is set to keep running if at all possible. If something suspends your thread, be sure that "Leave Application in memory" is set to Yes. CEP2 requires long run time and maximum throughput profile settings.
