There's no rule, one way or another. I usually only shut down when installing updates. Otherwise, you can just use sleep whenever you're not using it. Many users here have uptime (time between shutdowns) from several days to a few months.I recall reading that if I don't use the MBP for up to 2 days, then it's best to shut it down.
You can leave it plugged in while sleeping. If you're on battery, you'll use somewhere around 1% of battery for every hour in sleep mode. YMMV.Is there a limit to the amount of time a MBP can be in sleep mode? (like before the battery gets completely drained)
Sleep drain: You may notice the battery in your Apple portable may drain up to 1% per hour (24% per day) while the computer is in sleep mode. This is normal behavior.
Reading a few posts into this link you provided, they mention that shutting down, can in the long run, wear out the hard drive a bit more than just letting it sleep. Any thoughts?
The hard drive is not affected differently between sleep or shut down. In both cases, the hard drive is not spinning.Reading a few posts into this link you provided, they mention that shutting down, can in the long run, wear out the hard drive a bit more than just letting it sleep. Any thoughts?
