Better sleep or shut down to reduce battery power lost for MBP?

better sleep or shutdown the MBP late 2011 because it seems that sleep will make battery loss percentage even a fews...

Shutdown will preserve the battery charge level for the longest period of time.
Rechargeable batteries are subject to self discharge so it will still lose charge but at a much lower rate than while in sleep.

Macbook Pro shut down because the battery power ran out. Now I cannot start it and the battery will not charge. Only one green battery charge light lights up and blinks.

My Macbook Pro shut down because the battery power ran out. Now I cannot start it and the battery will not charge. Only one green battery charge light lights up and blinks on the left side. I am running Lion. How do I get this to charge and turn on? Thanks

If your model Macbook Pro is the calibrating model, let the battery calibrate.
If not, and are still under warrant or have Apple Care, give them a call and get a case number. Otherwise, take the computer to an Apple store or an AASP. Whichever is more convenient for you.

Macbook Pro (Mid 2009) Shuts down at 24% battery power

For the past few days my Macbook Pro, the one I've had since the summer of 2009, has been shutting down at random times. Not only does it shut down without warning but it restarts my clock to March 24 2001, at 7:30pm every time. What the heck? Especially since this week is finals week, I have to trust my computer to hold out for four more days before it can stop working, but until then I just want to know what the problem could be.

Time to recalibrate your battery meter .....

Computer Shuts down when on battery power at 80%

The battery power indicates anywhere from 80% to 90% and will shut down the computer.
No warning, No Low Battery indicator, No error messages.
The only way to boot up is to use the power adapter.
I have tried to reset the computer
I have tried to update the latest battery update, but it tells me it is already installed.
This computer is 8 months old.
Is there anything else I can try?

I had/have this exact same problem after I installed the battery update 1.3 on Macbook Pro a few days ago.
I tried a SMC reset & a PRAM reset, all to no avail.
I called Apple today & talked with 2 different agents explaining my problem. One askked me to do another PRAM reset, which I did, again, to no success.
So, they are sending me a new battery, which I am really hoping will solve my problem (Macbook Pro shutting down instantly on an almost full battery at around 84% while not attached to the power cord).
Thing is, I never had a problem with the battery before I installed this update, so this battery update 1.3 somehow corrupted my battery/settings, and unfortunetly once you run this update, your stuck.
There is no way to undo this update as it changes the firmware permanetly.
Ugh.
Next time, I am not going to be so quick when installing "updates", I apparently really don't need. This battery update 1.3 has just caused me headaches & problems on my new Macbook pro.
Heed my advice. Research firmware updates carefully before subjecting your computer to these unneeded "fixes".
My advice is to call Apple & let them know of this problem. Get a new battery. They were apparently unware of this problem update when I called today, and more people need to be vocal about this & complain about this apparently corrupt battery update.
Good Luck.

Ipod mini- 3/4 battery shutting down with "no battery power remaining"

After fully charging my ipod mini, while it still has 3/4 battery on the battery meter in the corner will shut itself down due to "no battery power remaining" if i push the NEXT button too many times in a row. This is a consistant problem and always happens when i have a half battery power or more. I do keep it in Shuffle mode, and i am fully aware that will drain the battery quicker, however there should be no reason a freshly charged ipod with 3/4 battery should not be able to shuffle a few songs without shutting down. Has anyone else ever had this problem or knows of any solution for fixing it? Any help would be appreciated!!

my ipod is doing the same thing...except when I turn it on it will say i have 3/4 battery for only about 10 seconds, then it turns off. All the other forums I have read say to get the battery replaced, but Apple can and usually does send a faulty battery so it might be time for a new ipod.

IPhone 5 shuts down at 37% battery power...

This has happened 6 times now - all random times (twice when using FaceTime, twice when taking pictures and twice when texting/emailing). When I try to reboot phone I get screen that shows no battery power remains and that you need to plug in phone. I then plug it in and it powers back on and jumps to 47% battery power. Anyone have this experience??

I, too am seeing this happen lately. I'd guess it's because my phone is a year old now but I'd prefer it to be something else. :)
I should mention that I'm still running OS6. I did the "upgrade" to OS7 on my iPad and I HATE it! I figure that eventually I'll have to move up to the new OS sooner or later but I'm holding off as long as possible!
Has anyone had any success in tracking down what the problem actually is?

Should I put it to SLEEP or SHUT DOWN?

Greeting everyone. I recently purchased my first Macbook, my first laptop ever. I've pretty much grown up using a desktop pc. I turn it on when I get home, put it on sleep mode when I leave it to watch tv or what not. If I'm done with it for the day, I turn it off.
Now before everone jumps on me for probably doing the wrong thing please note that I come from a "Turn it off when you're not using it kind of family". Can someone give me some pointers in using my new mac? For example, someone told me that I can actually leave my macbook in sleep mode the entire day even when traveling to and from school/work. Is this safe for my macbook? I apologize if this is such an elementary question.

I have found that my machines respond better when I just close the lid (sleep). It is important to understand that the laptop caches everything in memory to the hard drive before it goes to sleep, so you want to make sure you allow the extra time for that to happen (wait until the sleep light starts pulsating) before you move the laptop if you can. Otherwise you're moving the machine while the hard drive is still spinning. I know that the newer laptops typically have a Sudden Motion Sensor that will automatically park the heads under certain conditions, but why tempt fate? Depending on how many applications you have running, and how much RAM you have installed, going into sleep mode can take longer than you might expect. Whether you adapt a sleep or shut down operating preference (I prefer sleep- only shutting down every once in a while for OS installs, restarts due to problems, etc.), it is much more important to follow Apple's guidelines for calibrating the battery. Not only does following these instructions allow the computer to more accurately report the battery charge level, it also runs the lithium ion battery through a complete cycle - something that is needed every once in a while to keep it operating in tip-top shape. The instructions for the procedure are found here:

Macbook Pro random shut down whilst using battery

My Macbook Pro randomly shuts down whilst using battery power even though their is plenty of charge in the battery.
Any ideas??

does it do it when plugged in?
Also it sounds that there's a power failure and causing it to shutdown, I would get it serviced asap, the battery connector might be faulty.

Is it better to sleep or shut down at night?

Is it better to sleep or shut down when I'm through with my iPad for the night?

I have been letting mine sleep when not in use since buying it new almost a year and a half ago...has never caused any issues with it. Only time it has been shutdown is for aircraft take off and landing.

Sleep or shut down at night?

Hi, it just occurred to me that in summer with frequent lightning storms especially during the night, might it be a good idea to shut the computer down and disconnect the power adapter at night?
I tend to use the computer plugged in during the day, with short periods of battery use, and then at night I leave it plugged in and just close the lid. Even with old PC's I did this without a problem, but with my new MBP I don't want to take any chances!
Thanks,
Karen

Thanks.. re. shutting down at night, I thought there was an issue of wear and tear from starting up so often.. otherwise it would certainly be simpler to shut down and not worry about nighttime power surges.
I don't worry about wear and tear, because although technically it might be better to run your computer at full power 24/7 to avoid premature wear from thermal and power cycling, realistically nearly every Mac user either sleeps or shuts down their laptop at least once a day whether that's at night or merely to transport it (since it is a laptop after all) and therefore powering off is the norm, and it is not causing mass early laptop deaths.
We are also weighing leaving the computer plugged in versus the potential damage from a lightning strike, and we're saying the potential damage from sleeping or shutting down at night is assumed to be less severe than that of a direct lightning hit.
Re. sleeping the computer all night and draining the battery, I do that once a month to calibrate the battery, but isn't it recommended to not drain deeply too often?
You are right that is is recommended to not do deep discharges too often. But an overnight sleep does not drain the battery that far, maybe a few percent. What I didn't mention is that if your battery is new and fully charged, it will probably last around a week in sleep mode. One night off the charger isn't going to drain the battery unless, as I mentioned, it's an old battery with a fraction of its original capacity.

Sleep or shut down the laptop?

Is it better to sleep or shut down the laptop? I mean in general for the laptop, not necessarily to save battery or anything. Thank you!

No need to shut down unless perhaps the laptop is going to be in a travel bag for a while.
I just close the lid to stop using; open the lid to use.
I've been doing this routine since OS X 10.0.

Does it shut down with the power adapter attached? What color is the power adapter led?
Have you tried a SMC reset?
