How to add something like hibernation mode to a bot?

Question

Python

Hello everyone
I am writing my bot, personally for myself. I added a bunch of all sorts of goodies to it, such as finding out the weather, news, movie screenings, etc. But suddenly a question arose. How can I add hibernation mode to it (deep sleep, hibernation, work in the background) And so that it wakes up on a command like "bot init'. I explain why I need this
1) Firstly, I want to add the keylog function, i.e. keylog
2) Secondly, this bot works as a server, so I can connect to it from my phone.There are only a couple of functions in the client.And I would not want the bot to heavily load the entire system with all its functions.3
) My bot listens to my VK, and if a message arrives, he responds with something like “wait 5 minutes.” Again, I would not want the process to constantly hang on the command line.
4) It monitors the consumption of my RAM and if the load is more than 80% it tells me about it.
Thanks to everyone who answers
PS if anyone knows, tell me how to add it to autorun (start when you turn on the PC)
