Is it good to always shut down and then power on when needed? Or is it bad for a laptop
Is it good to always shut down and then power on when needed? Or is it bad for a laptop
A somewhat related note is keeping it plugged in. You do not want to run the battery all the way down and recharge it. If you have the ability to, you can leave it plugged in all of the time. The batteries do not need "training" like batteries of old.
Apple suggests that you do at least one drain and charge cycle per month though.
Turning a computer on, introduces stresses that aren't there by putting it to sleep. The only time I shut my computer down is when I put it in my travel bag. Other then that, I either leave it on, it put it to sleep.
Proof? I maintain that is complete nonsense and it doesn't matter whether you shut down or put the computer to sleep, especially with solid state drives.
Indeed, if you have filevault 2 installed I would recommend shutting it down. Putting the computer to sleep leaves the computer able to read the encrypted partition and have it accessed via the thunderbolt port. Not good if you have sensitive data and the laptop is stolen. Shutting it down means that without the password, the laptop will not decrypt the drive.
From man pmset:
The full command would be sudo pmset -a destroyfvkeyonstandby 1.Code:destroyfvkeyonstandby - Destroy File Vault Key when going to standby mode. By default File vault keys are retained even when system goes to standby. If the keys are destroyed, user will be prompted to enter the password while coming out of standby mode.(value: 1 - Destroy, 0 - Retain)
This would enable destruction of the FileVault key during standby for all -a power modes. That is UPS -u, battery -b and charger -c (wall power).
In older versions of Mac OS X, an attacker with physical access to the machine could plug in via Firewire (or Thunderbolt) and use DMA attacks to gain access to memory. This would let the attacker slurp out your password and thus defeat FileVault 2's protection. However, this vulnerability was fixed in Mac OS X 10.7.2.
I don't use FileVault 2, but in login options I have selected "Automatic login" to off, after wake up or turn on I have to write password. I don't think that "normal" people can read from FileVault or RAM when computer is in sleep mode.
Found on the Internet:
By the way, if you use your laptop every day, you better put to sleep. Sometimes you need to restart after upgrade. If you do not use it for a few days, you can turn it off.
If I put it to sleep should I always keep it plugged in?

Yea like making my 2000 dollar product last...
The only way to make it last is not to use it. There is no point in spending $2000 on something and then being to scared to use it how you wish.
I'm all for looking after your products but all this nit picking about turning them on and what to do about batteries etc is pointless nonsense will make no difference to the life of your machine and is bordering on insanity.
It doesn't matter how much it cost it is still just another PC and they fail when they fail.
Yea like making my 2000 dollar product last...
I use it believe me I just don't abuse it.. it's like everything else i dont buy a car and drive to the ground because I paid x amount of dollars for it.. I like to take care of my stuff.. Seems like some of you get offended by certain questions if that's the case stay off the post if what I say or others makes your granny panties bunch up
I'm not offended, if that's what you believe.
The computer will last as long as it will last, bar an accident like a spill or a malfunction.
My point was that no amount of fussing over it or anything for that matter will change that. Thus, it is my opinion that your time would be better off spent in another way.
If you disagree with that, and would rather spend time worrying about what you have no control over, then that's your choice.
Opinions are like ********** everyone has one don't worry about what I do on my time if I feel like asking a question about something I'm gonna do so and if you don't like it move on!
You're allowed to ask the question, just as I'm allowed to provide an answer. Nobody said anything about liking (or not) said question. No need to get angry if that answer doesn't suit you. If anything, you're the one "getting your granny panties in a bunch".
I wish you a good day nonetheless. Enjoy your mac!
