how to turn on macbook air without power button

Looking at the specs for a typical 2.5', internal HDD these days yields the following: Environmental (operating) Shock (half-sine wave) 400 G/2ms, 225 G/1msĮnvironmental (non-operating) Shock (half-sine wave) 1000 G/1ms If that happens, though, all hope is still not lost. However, some software may, intentionally or unintentionally, keep your MBP from entering stand-by mode. If the MBP is in 'stand-by', the HDD will not be spinning and is therefore very safe to transport.

If you are not using something like 'Caffiene', or some other 3rd-party tool to keep the MBP (Macbook Pro) actively running while it is closed, your MBP should enter stand-by within a minute or so, when the lid is closed to put into your backpack. If you're like me, however, you'll just suspend the machine and let the rest of the human race fall with you. All because you left the machine in a state that left the battery charged. If you're in constant fear of zombie apocalypses (like me), then you may be happy to know that your laptop in its powered-off state may end up having enough juice left in it, that when some survivor takes it from your corpse, they may manage to use it enough to solve some key problem and save humanity. Ultimately, the practical difference is so superficial that you may as well just do whatever you 'feel' is best. I think it also provides unnecessary (though trivial) wear-and-tear on your hard drive. I think it's a serious waste of your time to power-off.

I am trying to decide if it's worthwhile to take a few minutes to power it off properly daily before leaving office or doing it is virtually meaningless. Unless you're doing something really weird, it's not harmful. Anything that would generally damage the machine in a suspended-state would also damage it in an off-state. It could only be harmful if the machine is being woken up (and thus spins up the hard drive while the machine is being vibrated hard). Is it harmful to its hardware? If so, how and how much harmful?Īpple encourages people to use their machines like that. If you're going to run on battery for a while at home too, then the power cost of shutting down and booting up may end up being more than being suspended. Obviously being suspended will consume battery power slowly (very very slowly). Short answer: No, it's fine, don't spend another mental cycle on this.ĭo I need to power off my Macbook Pro during commute between home and office?Įither approach is fine.
