I am making computation on SageMath 9.3 (console) on my laptop (Huawei, Intel Core i7, Windows 10). Closing the clamshell puts the laptop to sleep (and so puts the running computation to stop). Then reopening it puts the computation to continue from where it stopped. Is it safe to do so? I mean for the computation (not for the laptop). I did some tests, and it seems to be ok (I mean I got the same output with or without closing the clamshell in the middle of the computation), but I would like to know whether it should be always ok.
