I have a question about using "keep" with "charging". I've heard people say
keep your laptop off to save energy.
But can you use the structure with "charging"? I am not sure if it can be used like "on/off".
Don't keep it charging overnight to save energy.
Is this how you would use "keep" and "charging"?

Don't keep it charging is perfectly comprehensible, but it's not exactly how I'd say this.
This has the same meaning as charging, but I think it's a more common way to say it.

Obviously that's not what you mean, and everyone would know that, but semantically what you're saying there is "Charging it overnight saves energy. I don't think you should save energy, so don't do that."
If you wanted to use charge, you can, I just wouldn't pair it with keep:
(The semicolon here has the same function of clearing up the ambiguity.)
If you want to use saves energy, you could say something like these:
