Shutting down a laptop when not using it longer than a few hours is much better to extend the lifespan of the laptop and protect it.
On my laptop computer if I'm gonna need it during the day and plan to return to the laptop within 30 minutes to an hour or 2 hours then I leave the laptop on in sleep mode and close the lid.
If I plan to be away from the laptop for more than 3 hours then I shut the laptop down to prevent it from overheating.
I don't use the computer all the time and mostly use my laptop when I'm in the living room, outside etc.
I also have my desktop computer that I leave on 24 hours per day 7 days per weeks so if I really need the computer sooner than expected I can go into my home office and get on the desktop computer to do something that needs done.
