Should I leave my macbook on at night

Should I shut down my Macbook Pro when I'm done using it at the end of the day?

The total length of time my MBP has been shut down in the more than three years I've owned it is under 12 hours. It sleeps whenever I'm not using it, including when I'm traveling with it. The original battery has about 200 cycles on it (it's rated for 300) and 87% health. I've upgraded the hard drive once and the RAM twice, and never had any trouble at all with the machine.

    Should I leave my macbook charging cable plugged in when I'm not using it?

    It won't hurt anything (i.e., it won't overcharge). It isn't a good idea to leave it plugged in 100% of the time. One common recommendation is to use the battery at least one cycle per month without ever deeply discharging it. Ways to do that would be to use it on battery power until it is discharged to 50% twice during a month or to 80% 5 times during a month or some other combination that adds up to roughly 100% usage once per month at a minimum. Another way of stating that is that you should use the battery sometimes.

  • Is it better to leave your macbook pro in sleep mode during the night or have it shutdown all night?

    Is it better to leave your macbook pro in sleep mode during the night or have it shutdown all night?

    During sleep, your MacBook consumes a little part of the battery, so it won't harm leaving it in sleep mode. Also, you will be able to start using it quickly, as you don't need to wait until Mac OS X turns on.
    I only recommend you to turn off the MacBook if you are not going to use it for days in order to save battery, but apart from that, you don't need to turn it off

  • Should i shut down my macbook air each night

    how often should i shut down my macbook air?

    if youre not using it for a few hours
    leaving your macbook both ON charge AND in sleep mode is bad on the battery
    merely in sleep is another matter, which is fine.
    Considerations for the long life of your MacBook. Handling and environmental care tips
    General consideration of your MacBook battery
    Contrary to popular myths about notebook batteries, there is protection circuitry in your Macbook and therefore you cannot ‘overcharge’ your notebook when plugged in and already fully charged.
    However if you do not plan on using your notebook for several hours, turn it off (plugged in or otherwise), since you do not want your Macbook ‘both always plugged in and in sleep mode’.
    A lot of battery experts call the use of Lithium-Ion cells the "80% Rule", meaning use 80% of the full charge or so, then recharge them for longer overall life. The only quantified damage done in the use of Lithium Ion batteries are instances where the internal notebook battery is “often drained very low”, this is bad general use of your notebook battery.
    A person who has, for example, 300 charge cycles on their battery and is recharging at say 40% remaining of a 100% charge has a better battery condition state than, say, another person who has 300 charge cycles on their battery and is recharging at say 10-15% remaining on a 100% charge. DoD (depth of discharge) is much more important on the wear and tear on your Macbook’s battery than the count of charge cycles. There is no set “mile” or wear from a charge cycle in specific. Frequent high depth of discharge rates (draining the battery very low) on a Lithium battery will hasten the lowering of maximum battery capacity.
    All batteries in any device are a consumable meant to be replaced eventually after much time, even under perfect use conditions.
    If the massive amount of data that exists on lithium batteries were to be condensed into a simplex, helpful, and memorable bit of information it would be:
    1. While realistically a bit impractical during normal everyday use, a lithium battery's longevity and its chemistry's health is most happy swinging back and forth between 20% and 85% charge roughly.
    2. Do not purposefully drain your battery very low (10% and less), and do not keep them charged often or always high (100%).
    3. Lithium batteries do not like the following:
    A: Deep discharges, as meaning roughly 10% or less on a frequent basis.
    B: Rapid discharges as referring to energy intensive gaming on battery on a frequent basis (in which case while gaming, if possible, do same on power rather than battery). This is a minor consideration.
    C: Constant inflation, as meaning always or most often on charge, and certainly not both in sleep mode and on charge always or often.

  • Is it better to leave my macbook plugged it.... when.... read more!

    Hi guys,
    do you think its better that i just leave my macbook plugged in all the time *if i can* ... or should I just use the battery whenever I feel like it? I know that your supposed to do at least one full drain with your computer at least once a month... but If i'm going from room to room and just feel like not dragging around an adapter, is it bad for the battery? or is it good becasue I'm using the battery more and keeping the parts moving and warmed up rather than just never really using it?
    Like right now my battery status is "not charging" even though its not plugged in!
    the only reason I like to keep it plugged in a lot is because I record music a lot, and can't really do that on a low battery power (if the macbook shuts off I could lose data)
    or is all of this really that big a deal?

    Hey lyssa, that does help a bit. What about how my battery drains to under 95 % even when it's plugged in... and then it charges back to 100% in like 20 minutes... is that bad for the battery, because it happens when its plugged in (it slowly drains to below 95%... will that add battery cycles onto my laptop?
    That's inevitable and not particularly bad. What would be bad would be that it went down to 99% and tried to top off the charge to 100%. That would mean more attempts to charge up to 100%. It's not that you don't want it to charge up to 100%, but it's going to degrade slightly every time the battery capacity gets to 100%. Near 100% is where it generates a lot more heat and tends to degrade battery capacity the most. Taking it down below a certain capacity also seems to degrade the battery. However - if you want to actually use the battery, these are normal things and the battery is considered a replaceable part.
    I won't bore you with the details, but hybrid car batteries are designed to stay between 40-75% of theoretical capacity. By avoiding the extremes of charge and discharge, they can go through hundreds of thousands of these partial charge-discharge cycles while a standard use battery might go through maybe under 1000. The overall amount of energy cycling through a hybrid car battery would be maybe 30-50 times more than a standard use battery. Of course MacBook charging system isn't designed for that kind of use.
    Charging a lithium rechargeable battery is an exercise in careful management of heat generation and battery life. Some of the earlier lithium rechargeable charging systems weren't very good and didn't slow down the charge as it approached 100%. You'd get overheating batteries as well as a few that caught on fire (the Sony factory fire in the 90's took out most of the world's Li-ion battery production at the time). Fortunately lithium battery charging technology has improved to the point where fires are extremely rare.

  • Should I shut down my iPhone every night? Sleep vs shut-down.

    Hi, If I never use my phone during the night, should I shut it right down every night? How much energy is used when the iPhone "sleeps" for 8 hours?
    Thanks for your thoughts on this!

    My battery will loose about 10% (polling email every hour, and push IM left on) over 7.5 hours.
    You can leave it on and I think Apple intend people do, because otherwise alarms will not go off, I use the alarms to wake me up The best option is to leave it on and plugged in.

  • When should I purchase a MacBook Air, and what upgrades are worth it?

    My MacBook Pro (early 2011) is moving as slow as a dinosaur... we are hoping if I get a MacBook Air for school and we only use one account on the Pro (instead of leaving both logged on and switching back and forth), we can get by for a few years without the cost of a new Pro. (I am a grad student. Money problems make it almost tempting to even get a PC at this point.)
    With a minor "refresh" rumored in the upcoming days for the MacBook Air, and the 12" Retina coming a few months down the road... and with my next school term starting in May-- when should I get a MacBook Air?
    I will be getting the 11" since it is cheapest.
    Also, when considering the question of extending the lifetime of the computer (hoping in 4 years it doesn't slow to a crawl like our Pro has), what is more important-- upgraded processor, or RAM?

    While it may be that the hardware you have is responsible for the slow performance, it is also possible that third party software incompatibility is the cause.  If you run EtreCheck and post the results here, someone might be able to spot something.

  • Should i leave charge plug when it is fully charged?

    Should i leave charge plug when it is fully charged? I read that my macbook pro with retina display (Early-2012) has 1000 charge-cycle. If i do not unplug it when it is fully charged, it won't count plus for charge-cycle. However, is it beneficial?
    Thanks a lot.

    You can leave it plugged in whether using it or not. It will not harm the battery:

  • Should I leave my imac turned on all of the time?

    Should I leave my imac on all of the time....and if so why?..Thanks

    The debate is as old as computers themselves.    The most important thing to remember, is lightning is a machine's worst enemy, and no surge protector can defend against all lightning strikes.  As the proverbial Clint Eastwood said:  "Do you feel lucky today?"
    Look at your energy usage on your electric bill on a similar month weather wise with and without the computer on all the time.  
    See if you can run with Energy Saver on without freezes, as many third party devices don't support Apple's low power mode.  
    Once a month it is good to run in Screen Saver instead of Energy Saver as cleaning up happens on the system upon wakeup from sleep, or in the middle of the night if only Screen Saver or nothing is running but applications.   Energy Saver delays that cleanup.  You can get Macjanitor or Anacron to run that cleanup when you want.

  • Does it harm the battery to leave the MacBook pluged in all of the time?

    Does it harm the battery to leave the MacBook pluged in all of the time?

    It is OK to leave your battery hooked to the charger most of the time. The only time I unhook mine from the charger is when I calibrate. You should calibrate your battery once a month. This keeps your battery healthy for when you need to use your MacBook portable.

  • I updated to MacBook pro last night and now safari won't open

    I updated my MacBook Pro last night and since I did this I can not open Safari.  It crashes and sends a report to Apple.  Not tech smart enouh to figure it out can anyone give me simple suggestions?

    Please elaborate on what exactly you mean by it "won't open".
    Do you try to launch it and get an error message from the Finder (for example, something like "This application is damaged and cannot be launched....")? Does an icon for the application ever appear in the Dock when you try to launch it? Does it start to launch and then immediately crashes (Finder will display an "unexpectedly quit" dialog)? Or does it start to launch and never seems to "finish" launching (in other words, it basically hangs and is unresponsive)?
    If the application crashes, please post the contents of the crash log here.
    Otherwise, if the application seems to be hanging, can you, before attempting to launch it, open the Console.app application (it's in the /Applications/Utilities/ folder), and see if anything is reported when you attempt to launch it? If so, please post it here.

  • How can I set up Cinema Display as a main screen and leave my macbook pro as a second screen instead?

    How can I set up Cinema Display as a main screen and leave my macbook pro as a second screen instead?

    I learned that the Dock is positioned at the chosen edge of whatever Display is positioned farthest to that side.  E.g. for the Dock to be positioned on the right side of the Cinema Display (instead of the right side of the MacBook), the Cinema Display must be oriented (by dragging) to the right of the MacBook monitor on the "Arrangement" tab of the Displays Preference Panel.

    Hey Clintonfrombirmingham
    I called Apple technical support in Denmark, but with no positive reply.
    She couldn't do anything, and said that They had sent a recall Email about the problem and with their offer to repair the Macbook Pro, but I'd never recieved an Email about the problem. She wasn't in power to make an exception. It can't be true that i paid a lot of money, for a product that can't barely stand on its own feets, Apple didn't tell me that the product I was about to buy, would restart every 5 minute. and now when  they know the problem, they wont repair it? it just don't make sense for me. If a car seller discovers that all the brakes in a car he had sold, will crash after some years he will call all the cars back to repair no mater what. i just don't understand how Apple will make good service for their custumers, by extending the warranty from 2 to 3 years, but wont take the computers there is a little bit to old, 4 months will make the difference. i can't believe it.
    What can i do now? 
    best regards Oskar

    I have a 2 year old Air with 1.8 GHz i5 4 GB that is more than adequate and extremely fast for the uses you describe.
    Is battery life a factor in your decision? If so, knowing that may help someone else give you some more input.

  • How long should I leave my iPhone in rice?

    My younger sister accidently spilled water on my iphone 4. It seemed okay but it kept trying to turn itself off so I put it in rice and its been in there for about 3 days now. How long should I leave it in there to insure that it will be OK?

    you can't be sure if it's ok
    But three days should do the trick. Good luck
